Char/Misc/IIO/others driver changes for 7.4-rc1
Here is the big set of char/misc/android/iio and other small driver
subsystem patches for 7.4-rc1. Loads of stuff in here, larger than
normal. Highlights include:
- removal of the C binder code, the rust version is stable and will be
used going forward in a few billion devices. Great job by those
developers.
- loads and loads of IIO driver updates and feature additions
- speakup driver fixes and updates
- mhi driver updates
- mei driver updates
- xillybus driver fixes
- comedi driver fixes
- lots of coresight driver updates
- Interconnect driver updates
- nvmem driver updates and fixes
- slimbus driver updates and fixes
- spmi driver updates and fixes
- lots of tiny misc and char driver fixes based on people scanning for
things.
All of these have been in linux-next for a while with no reported
issues, other than a merge conflict with one of the rust tree files,
which should be simple to resolve.

bus: arm-cci: Drop cci-control-port node reference in __cci_ace_get_port()
__cci_ace_get_port() looks up the device's "cci-control-port" node with
of_parse_phandle(), which returns the node with its reference count
raised, and only compares the pointer against the probed ports. Neither
the match nor the no-match return releases it.
Drop the reference on both paths once the comparison is done.

cci_ace_init_ports() looks up each possible CPU's node with
of_get_cpu_node(), which returns the node with its reference count
raised, but never releases it: neither when the CPU has no ACE port nor
after the port has been recorded. Before the commit below the loop used
for_each_child_of_node(), which manages the references itself.
The node is only needed for the port lookup, so drop the reference right
after __cci_ace_get_port().

bus: mhi: ep: clients: Add loopback driver for data path testing
When an MHI endpoint device runs Linux, there is no firmware to implement the LOOPBACK channel echo that real modem firmware provides. Without an endpoint-side driver, the host loopback test has no software echo partner and cannot exercise the full end-to-end MHI data path. Add an endpoint-side loopback driver that binds to the LOOPBACK channel and echoes received data back to the host. An ordered workqueue is used for asynchronous processing to preserve packet ordering. Together with the host-side loopback driver, this enables complete MHI data path validation for Linux-based endpoint devices.

bus: mhi: host: clients: Add loopback driver with sysfs interface
The MHI specification defines a LOOPBACK channel. The endpoint firmware echoes back whatever the host sends on this channel. Without a host-side driver, there is no way to exercise this channel to validate MHI data path integrity between host and endpoint. Add a host-side loopback driver that binds to the LOOPBACK channel and expose a sysfs interface for data path testing. The sysfs interface allows users to configure TRE buffer size and count, trigger a loopback test, and read the result. The new sysfs ABI is documented under Documentation/ABI/testing/, not stable/, since this is a new interface without established API guarantees yet. It is unrelated to the existing stable MHI sysfs ABI documented in Documentation/ABI/stable/sysfs-bus-mhi, despite both being covered by the same MAINTAINERS entry.

bus: mhi: host: pci_generic: Add Quectel RM500Q-AE support
The Quectel RM500Q-AE (SDX55) enumerates with the Qualcomm SDX55 ID 17cb:0306 and subsystem ID 17cb:5002, so it binds to the generic qcom-sdx55m entry. That configuration expects QMI on channels 14/15, which this module's firmware does not answer: the modem probes, but every QMI request over the control channel times out and no data session can be set up. Users of this module have had to fall back to Quectel's out-of-tree driver. Like the other Quectel modules, the RM500Q-AE provides MBIM control on channels 12/13 and data on IP_HW0_MBIM. Add an entry for its subsystem ID, which no other entry in the table uses, that reuses the Quectel em1xx channel configuration. The EDL image name is the one the generic SDX55 entry already uses. Tested on a Xunison Exigo D50 5G (IPQ5018) with modem firmware RM500QAEAAR13A03M4G: the modem probes as quectel-rm500q and exposes wwan0mbim0, wwan0at0 and an MBIM network device. A data session set up with mbimcli and with OpenWrt's umbim reached 160-180 Mbps, the limit of the cell.

bus: fsl-mc: drop the fwnode links of the dpmacs nodes
A DPMAC node under dpmacs/ is never the fwnode of any device: the fsl-mc bus creates dpmac.N objects without one, then dpaa2-mac finds its node in dpmacs/ at connect time. fw_devlink therefore attaches the supplier links of those nodes (phys, ...) to the nearest ancestor device, the fsl-mc bus, as SYNC_STATE_ONLY proxies. device_link_add() refuses such a link once the consumer has probed, and fw_devlink logs the refusal as an error. On an LX2160A board with 4x25G DPMACs for which phys = <&serdes_1 N>, the Serdes PHY binds after the bus and then at every boot it shows: fsl_mc_bus 80c000000.fsl-mc: Failed to create device link (0x180) with supplier 1ea0000.phy for /soc/fsl-mc@80c000000/dpmacs/ethernet@3 once per port! To fix it, when the root MC bus probes, purge the fwnode links of every child of its dpmacs node, so fw_devlink has no supplier link left to proxy to the bus and no longer tries to create those device links.

bus: mhi: host: pci_generic: Fix runtime PM imbalance for no_m3 devices
mhi_pci_probe() drops the runtime PM reference taken by local_pci_probe()
only when the device supports both PME from D3hot and M3, but
mhi_pci_remove() re-takes it based on PME capability alone, without
checking no_m3.
For a device that is PME capable and has no_m3 set, probe therefore never
drops the reference while remove takes an extra one, leaving the runtime
PM usage count one higher after every bind/unbind cycle. That is benign
for the device being removed, since the PCI core resumes it to D0 on
unbind regardless, but the struct device outlives the binding, so the
count accumulates across repeated cycles and can end up preventing
runtime suspend altogether.
Cache no_m3 in the driver's private data, as is already done for
reset_on_remove, and gate the removal side on it as well. Unlike
reset_on_remove it is cached for virtual functions too, because the probe
side gate tests info->no_m3 for physical and virtual functions alike.
QDU100 is currently the only device that sets no_m3.

bus: fsl-mc: register the object drivers after misc_class exists
Unbinding and re-binding the root DPRC fails with:
sysfs: cannot create duplicate filename '/dev/char/10:256'
misc_register / fsl_mc_uapi_create_device_file /
dprc_setup / dprc_probe
It happens when the fsl-mc bus probe is not deferred, without SMMU:
- the dprc driver is registered at postcore_initcall,
- the DT node is populated at arch_initcall_sync,
- the root DPRC probes right there, before misc_init() has
registered misc_class at subsys_initcall.
misc_register() still succeeds but the device gets
no class, so misc_deregister() at unbind cannot find it:
the minor is freed while the device and its /sys/dev/char/ link leak,
and then the next bind collides on the same minor.
Let's move the dprc and allocator drivers registration, and
platform_driver_register(), to subsys_initcall_sync, after misc_init()
at subsys_initcall.
bus_register() and the platform-bus notifier stay at postcore_initcall
so that fsl_mc_bus_notifier() still pauses the MC before the SMMU is probed.

Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

MHI Host
-------- - Add SAHARA channel support in the pci_generic driver for Foxconn products. This allows capturing crashdump (ramdump) using the in-kernel sahara client driver. - Add support for devices with no M3 state. Some devices do not support the M3 power state due to hardware issues. For those devices, MHI bus will now run the full host-side suspend/resume sequence but skip the device-side M3/M0 handshake, so any transfer queued by clients during suspend is deferred until resume. - Set 'mhi_cntrl->no_m3' flag in the pci_generic driver for the QDU100 device so that the MHI bus also skips the M3 transition during system suspend. Earlier, the flag was only used to disable runtime PM, but the system suspend path was still transitioning the device to M3. - Fix sys error transition latency by polling for the state transition in mhi_pm_sys_error_transition() instead of waiting up to 24 seconds for an interrupt from the device. Since a device that has been reset (e.g., via AT!RESET) is not guaranteed to raise one. - Flush the posted write after writing to MHI_SOC_RESET_REQ_OFFSET in mhi_soc_reset() so that the reset actually reaches the device before the caller's post-reset delay begins. - Fix controller cleanup on EDL sysfs failure in mhi_register_controller(). The error path was leaving the device registered when sysfs_create_file() failed. MHI Endpoint ------------ - Add mhi_cntrl->flush_async() callback to drain the in-flight async DMA read/write operations issued through the MHI controller driver. This is used by the MHI EP stack before disconnect to avoid UAF where a late DMA completion could invoke a now-invalid xfer_cb(). - Implement the flush_async() callback in the PCI EPF MHI controller driver by waiting for the in-flight DMA operations to complete and then flushing the DMA workqueue. Since I'm the maintainer for this PCI EPF driver, I'm taking this patch through MHI tree due to dependency. - Flush the in-flight async transfers before notifying disconnect in mhi_ep_abort_transfer() to fix a UAF, where a success callback delivered after the -ENOTCONN notification could reference resources already freed by the client. - Fix device refcount leak in the error path of mhi_ep_create_device() when dev_set_name() or device_add() fails. Common ------ - Clean up kernel-doc warnings in include/linux/mhi.h. - Add Jeff Hugo as the Reviewer of MHI bus. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEZ6VDKoFIy9ikWCeXVZ8R5v6RzvUFAmp1ccAACgkQVZ8R5v6R zvX0JwgAhBLZ58NVLu194k1Y5CuSje6qOz0BwP33eLJcjzahkOtwue9Z7M4qZaxQ RlPQ6Eugqw6StN0orAiYjpitTS9efQ6MidJHYTDXb3f+9LvOoYwW7UquYKdxKs/3 qf9nY3ITeBWa/yOaKnkOjK8hb6LQYccMcS0J8t0BojqN0ReT8hzxHPekS50xlTsa ltUGC4J7gsLWzjuxbQXwL/xOjoRorF+fqDDTdAFBo3CqiAWe0fBVIIqifKH36m5U SRNNVNRcsGMHR4fTPBieLxgp28d5Von1Dqj4+Qh3IN2vECYAdvCX9SvGim0vsvXD j3FwrEmQniNNtndJ9Zrk20ismlN2rA== =491M -----END PGP SIGNATURE----- Merge tag 'mhi-for-v7.3' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mani/mhi into char-misc-next Manivannan writes: MHI Host -------- - Add SAHARA channel support in the pci_generic driver for Foxconn products.

bus: mhi: ep: Flush async transfers before notifying disconnect in mhi_ep_abort_transfer()
mhi_ep_abort_transfer() notifies the client drivers about the channel disconnect using -ENOTCONN and only then flushes the ring workqueue to drain the in-flight transfers. But the async DMA transfers issued by the ring workers can still complete after the notification. And the completion handlers trigger the client xfer_cb() as long as it is set. So a transfer completing during the flush can deliver a success callback to the client even after it has been notified about the disconnect. This can lead to UAF (Use-After-Free) issues as the client can free its per-transfer resources in response to the -ENOTCONN notification and the trailing success callback would then reference the freed resources. So to fix this issue, disable all the channels first to prevent new transfers and then drain both the ring workqueue and the in-flight async transfers before notifying the disconnect. The completion and queue paths bail out once the channel state is not MHI_CH_STATE_RUNNING, so disabling the channels upfront makes sure that no new transfer sneaks in during the drain and all the pending completions are delivered while xfer_cb() is still valid.

bus: mhi: ep: Add mhi_cntrl->flush_async() callback to flush the async read/write
MHI EP stack makes use of the MHI controller drivers like MHI EPF to do read/write to the host memory. And that driver is free to use mechanisms like DMA to offload the read/write operations. So if DMA is used for offload, then there is no guarantee that those DMA operations would be completed by the time mhi_ep_remove() gets called. This can lead to UAF (Use-After-Free) issues as the DMA callback can trigger xfer_cb() even after mhi_ep_remove() has returned. So to fix this issue, introduce the mhi_cntrl->flush_async() callback and call it in mhi_ep_remove() to drain all the in-flight async transfers before disconnecting the channels. The completion handlers keep triggering xfer_cb() as long as it is set. So flushing the transfers after notifying the client about the disconnect (-ENOTCONN) would still let a success callback slip through afterwards and lead to the same UAF. So disable the channels first to prevent new transfers, then flush the in-flight transfers so that their completions are delivered while xfer_cb() is still valid and only then notify the disconnect and clear xfer_cb().

bus: mhi: host: Fix controller cleanup on EDL sysfs failure
mhi_register_controller() adds the controller device before creating the
optional trigger_edl sysfs file. If sysfs_create_file() fails, the error
path only drops the device reference and leaves the device registered.
Hence, call device_del() in the error path before put_device().

bus: mhi: host: Add support for devices with no M3 state
MHI bus transitions the device into M3 state during suspend and back to M0 state during resume. But due to hardware issues, some devices do not support M3 state. To support these devices properly, MHI bus needs to skip transitioning the device to M3 during suspend and back to M0 during resume. For this purpose, introduce the 'mhi_cntrl->no_m3' flag and allow it to be set by the MHI controller drivers. Once set, this flag lets the MHI bus skip transitioning the device to M3/M0 during suspend/resume. But, simply skipping suspend/resume for such devices is not sufficient, as it leaves the MHI host in M0 state with device access enabled. Client drivers that do not implement PM callbacks (for instance, the non-freezable rx_refill worker in mhi_net driver) could then keep ringing channel doorbells and issue MMIO to the device even after the controller driver has disabled it and moved it to D3 during its own suspend, resulting in access to a powered down device. So instead of skipping the entire suspend/resume operation, run the full host suspend/resume sequence but without the device-side M state handshake. During suspend, only transition the host to M3 without sending the MHICTRL M3 command or waiting for the device M3 event. During resume, bring the host back to M0 through mhi_pm_m0_transition() without sending the MHICTRL M0 command. With the host in M3, all device access is gated by MHI_DB_ACCESS_VALID() and MHI_REG_ACCESS_VALID(), so any transfer queued by the clients during suspend is deferred until resume, where mhi_pm_m0_transition() rings the pending doorbells.

bus: mhi: host: Flush the posted write after writing to MHI_SOC_RESET_REQ_OFFSET
mhi_soc_reset() tries to reset the device by writing to the
MHI_SOC_RESET_REQ_OFFSET register. But it doesn't do a read-back to ensure
that the write gets flushed to the device before returning to the caller.
This may lead to the delay (if implemented) on the caller to be
insufficient, if the posted write doesn't reach the device before the
delay.
So add a read-back after writing to the MHI_SOC_RESET_REQ_OFFSET register.

bus: qcom-ebi2: use managed resources for clocks and children
qcom_ebi2_probe() enables the EBI2 clocks manually and populates child
devices manually. Several later failure paths can then return without
disabling the clocks or without relying on the driver core to undo child
population.
Use devm_clk_get_enabled() for both clocks and
devm_of_platform_populate() for children. This lets the driver core
unwind the resources automatically and removes the hand-written error
labels.

bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation
mhi_ep_create_device() takes one device reference for the UL channel and
another for the DL channel after allocating the transfer device. These
references are normally released by mhi_ep_destroy_device() before the
device itself is removed.
If dev_set_name() or device_add() fails, the error path currently drops
only one reference. The remaining channel references keep the device
from being released and leave the channels associated with a device that
was never registered.
Route both failures through a common unwind path that drops the DL
channel reference, the UL channel reference, and the initial reference
from device_initialize().

bus: mhi: core: Fix sys error transition latency
Bring forward the idea to fix the power down latency in mhi_pm_disable_transition() further to mhi_pm_sys_error_transition() so that the transition into system error (triggered by AT!RESET) in the modems won't have to return only after the timeout of up to 24 seconds. Once the device gets reset, there is no guarantee that it will send an interrupt to indicate the state transition. So polling is the sensible option here.

bus: qcom-ebi2: Fix clock leak on probe failure
qcom_ebi2_probe() enables the EBI2X and EBI2 clocks before it walks
child nodes and populates child devices. If reading a child node's reg
property fails, or if of_platform_default_populate() fails, probe returns
without disabling either clock.
Route those failure paths through the existing clock cleanup labels so a
failed probe does not leave the clocks prepared and enabled.

bus: ti-sysc: Fix /chosen node reference leak
sysc_init_stdout_path() gets the /chosen node with
of_find_node_by_path() to read stdout-path. The function then overwrites
the local node pointer with the stdout-path lookup result, or exits on
error, without dropping the /chosen reference.
Keep the /chosen node in a separate variable and put it after the
stdout-path value has been used for the lookup. The successful stdout
node lookup remains referenced by the cached stdout_path pointer.

Allwinner driver changes for 7.2
Mostly changes to the SRAM driver to allow for one SRAM region to be "claimed" by multiple changes. When a region is "claimed" it is removed or disconnected from the CPU's view. This is needed on the H6 and H616, which have one alias region seemingly shared between the video codec engine and the display engine. One minor fix for the RSB driver is also included. -----BEGIN PGP SIGNATURE----- iQJEBAABCgAuFiEE2nN1m/hhnkhOWjtHOJpUIZwPJDAFAmod2AsQHHdlbnNAa2Vy bmVsLm9yZwAKCRA4mlQhnA8kMCUND/4h+xocrSMz4T+gHAvffsGItDQrtyLreXem GNIdY7whCRo+6KgipnTgXtvqRCzBhiQx9PYM3BTLNLUCURdM0NAcooE/f1kidVOI BHOTvfX1cy9eoGVJpZnfMAdMT/MlIw6LC7C1n1y8H14q1ERWkAOeO+k1VE9lMbIj jI9YWCFPvq29F+gEZAlCZXZnMWkgrJiLixnVYyi32P1k/u3ykqoNx7TKHWPsWaj5 /lS22YJUkcf0ARAJhcTElxYLytuhUCE68KKYVD7cN8uojebbcTAJLSkO7INtEdD/ USkY5sdq1cmDQ42ejgSPkcaL3etwBAha1NceKFLEAYVto6GUziOmXaGw8TLJVMD7 8ILjzOVj28iUADqy43tvwkqzDNDgn1xy+wmZSiSb6b9N+htDNKHh37R8NeJd0EwY 8YC/r5H5JqwBFQ0PWXHnjeFNlp6lBZ3G/QWU9ztnsCaDKp8P4jtl8wCF843lACtj BKPFCQ/+dkAlxExClaUo1JewJqhjyghpLmoWRMy/azbkdx7B100hH3DabAicN7JH 1lJ+rvIgTmmlwmGYceQ6sdg//M1b+3emTQ2kX3cgPCra8srKnp5ZkJzwtK0J9OHv XEFzB9rtvBPYvKt0dk/eaQAKAZIq82j9vdrtMzI1A5LeUF3VMEr7BxXxplBdwAH6 TSIElm0ktA== =n5X7 -----END PGP SIGNATURE----- Merge tag 'sunxi-drivers-for-7.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into soc/drivers Allwinner driver changes for 7.2 Mostly changes to the SRAM driver to allow for one SRAM region to be "claimed" by multiple changes.

bus: ts-nbus: drop unneeded dependency on OF_GPIO
OF_GPIO is selected automatically on all OF systems. Any symbols it controls also provide stubs and are private to GPIOLIB anyway so there's really no reason to select it explicitly.

bus: sunxi-rsb: Always check register address validity
The register address was already validated for read operations in
regmap_sunxi_rsb_reg_read before being truncated to a u8. Write operations
have the same set of possible addresses, and the address is being truncated
from u32 to u8 here as well, so the same check is needed.

bus: mhi: ep: Protect mhi_ep_handle_syserr() in the error path
All the callers of mhi_ep_handle_syserr() except mhi_ep_process_cmd_ring()
are holding the 'state_lock' to avoid the race in setting the MHI state. So
do the same in mhi_ep_process_cmd_ring() for sanity.
