The LM3559 is very similar to the LM3560, but it operates at much lower
currents. This may result in incorrect current selection if LM3560 ranges
are applied to the LM3559. Implement driver data matching to use
device-specific current configurations.
Since the driver no longer supports platform data and device configuration
is performed more granularly, move the remaining enums from the header
into the driver file and remove the header.

Since there are no users of this driver via platform data, remove the
platform data support and switch to using Device Tree bindings.
Converting to Device Tree assumes dynamic and independent registration of
LEDs. To monitor the configured LEDs, a bitmap has been added. This makes
LED cleanup more robust and less context dependent.

The existing driver does not call media subdev registration, making it
invisible to the media framework. Since the LM3560 supports two
independent LEDs, register each LED as a separate media entity.
Because registering LEDs before device initialization may cause access
attempts before the hardware is ready, lm3560_init_device has been moved
before the subdevice initializations.
An additional helper, lm3560_subdev_cleanup, was added to release LED0 if
the initialization of LED1 fails, and to deregister both LEDs in the
remove function.

sun4i_csi_start_streaming() returned -EINVAL when no matching CSI

vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued

rtl2832_sdr_start_streaming() had multiple error paths that hit this
trap: two direct early returns (-ENODEV, -ERESTARTSYS), plus six
`goto err` paths covering subdev s_power, tuner setup, ADC setup,
stream-buffer allocation, urb allocation, and urb submission failures.
None of them returned the queued buffers.
The original function had no distinct success exit and fell straight
through into the err label, which previously only did mutex_unlock and
"return ret". Adding queued-buffer cleanup at err must therefore be
paired with an explicit success return; otherwise every successful
start would also drain the buffer queue and kill streaming. Add that
success return, then add rtl2832_sdr_cleanup_queued_bufs() at the err
label and before each early return.
The cleanup helper takes a vb2_buffer_state argument so that the
start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as
expected by userspace on start_streaming failure) while stop_streaming
keeps its existing VB2_BUF_STATE_ERROR semantics.
This mirrors the uvcvideo fix in commit 4cf3b6fd54 ("media: uvcvideo:

The err label still does not roll back power_ctrl(), frontend_ctrl(),
the POWER_ON flag, or stream/URB allocations that may have happened
before the failing step. Those are pre-existing leaks of a different
class and are not addressed here.

vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued

msi2500_start_streaming() had five error paths that all hit this trap
and were further tangled by ret-overwriting between calls:
- -ENODEV when the USB device was already disconnected
- -ERESTARTSYS when mutex_lock_interruptible() was interrupted
- msi2500_set_usb_adc() failure: ret was silently overwritten by
the next call (msi2500_isoc_init), so the error was lost entirely
- msi2500_isoc_init() failure: cleanup_queued_bufs was called, but
the function then fell through to msi2500_ctrl_msg() and again
masked the original error by overwriting ret
- msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all,
leaving isoc URBs submitted with no way for the driver to consume
them
Consolidate the error paths into a small goto chain. Every failure
now stops the function, drains the queued-buffer list, and returns
the real error code. The ctrl_msg failure path also rolls back the
preceding msi2500_isoc_init() via msi2500_isoc_cleanup() before
unlocking and draining.

Add an in-tree AVMatrix HWS PCIe capture driver. The driver supports
up to four HDMI inputs and exposes the video capture path through
V4L2 with vb2-dma-contig streaming, DV timings, and per-input
controls. Audio support is intentionally omitted from this
submission.
This patch also adds the MAINTAINERS entry for the new driver.
This driver is derived from a GPL out-of-tree driver.
Changes since v6:
- v6 accidently contained legacy history, resubmitting with latest
- remove an unused mode-change label reported by W=1
Changes since v5:
- keep queue_setup() and alloc_sizeimage on the logical sizeimage value
- drop the dead queue_setup() fallback that rebuilt pix.sizeimage
on the fly
- clarify that hws_calc_sizeimage() models the packed-YUYV-only path
- add Assisted-by attribution for Codex
Changes since v4:
- replace plain 64-bit elapsed-time divisions in debug logging with
div_u64() so i386 module builds do not emit __udivdi3 references
Changes since v3:
- fold the MAINTAINERS update into this patch so per-patch CI sees the
new file pattern
- wrap the validation text for checkpatch
Changes since v2:
- keep scratch DMA allocation on a single probe-owned path
- avoid double-freeing V4L2 control handlers on register unwind
- drop the extra per-node resolution sysfs ABI
- turn live geometry changes into explicit SOURCE_CHANGE renegotiation
- report live DV timings and reject attempts to retime a live source
- stop advertising RESOLUTION source changes for fps-only updates
- keep live fps state across harmless S_FMT restarts
- stop exposing an unvalidated DV RX power-present signal
- clean the imported sources for checkpatch and W=1 builds
Validation:
- build-tested with W=1 against a local kernel build tree
- compiled the driver with ARCH=i386 allmodconfig and verified the
resulting hws_pci.o, hws_video.o, and hws.o do not reference
__udivdi3

The only users of the non-PAS setup on SC7280 platform are the ChromeOS
devices, which were cancelled before reaching end users. Iris, the
alternative driver for the same hardware, does not support non-PAS
setup. It is expected that in future both Venus and Iris devices will
use different ABI for non-PAS (EL2) setup.
In order to declare only the future-proof hardware description drop
support for non-PAS setup from the SC7280 Venus schema (breaking almost
non-existing SC7280 ChromeOS devices).
The dropped iommus entry reflects the extra stream, which should not be
treated in the same way as the main one (which doesn't match the usage
described by the iommus definition).

On SM8250 most of the video clocks are powered by the MMCX domain, while
the PLL is powered on by the MX domain. Extend the driver to support
scaling both power domains, while keeping compatibility with the
existing DTs, which define only the MX domain.

First of all, on SM8250 Iris (ex-Venus) core needs to scale clocks which
are powered by the MMCX domain. Add MMCX domain to the list of the power
domain to be used on this platform.

Now as all UBWC configuration bits were migrated to be used or derived
from the global UBWC platform-specific data, drop the unused struct and
field definitions.

The UBWC max_channels spreading is specified in the Iris driver, but it
also can be calculated from the platform UBWC config. Use the platform
UBWC configuration instead of specifying it directly in the source.
