We try to avoid to create and look up parent domain hierarchy, which is
a normal way we need because it's indeed is a hierarchy. Instead we set
affinity via parent irq by using irq_set_affinity API.

Wlan devices support for RK platform has changed as the function driver
would cut down the power before host driver take place. So L2 must fail
now. We don't need to waste time for waiting for L2 to happen.
Meanwhile, given that the L2 handshake is a MSG TLP level operation, we
don't need such a long time to wait for timeout, in case some buggy devices
wouldn't support it.

Rockchip platforms supported outband msi routine via GIC ITS.
If msi irq is set, that means we start to support inband msi on
some specific platforms.
For inband msi support, we need SoC to provide msi specified interrupt
and MSI message can be interpreted by PCIe controller to manage MSI
routine.

It's better to force link into L2 before we power off devices,
especially if link is in L1. L2 routine is fully defined as:
1) host brings all downstream components back to D0 and L0 before
PCIe stack set D2hot to all devices.
2) send PME_Turn_Off to downstream components and wait for PME_To_Ack
3) check if we are ready to enter L23
4) check if link is already in L2
5) release all kinds of resources including power, #PERST, etc.
6) reset controller when resume
7) brings all downstream components to L0s and L1 after resume

gpiod_get_value would take gpio active state into count. So
the default pattern should be like prsnt-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>
to indicate that 1 means no devices. If we need 0 to indicate no devices,
we should use GPIO_ACTIVE_HIGH instead.

prsnt-gpios can be defined in DTS for showing if PCIe device is present
or not. By default, low voltage means device is present defined by PCIe
ECM spec. However, some buggy board may invert this voltage level. So
if you need high voltage to show the device is present, please add
rockchip,prsnt-active-high as well.

The current ATU setup only supports a single memory resource which
isn't sufficient if there are also prefetchable memory regions. In order
to support multiple memory regions, we need to move away from fixed ATU
slots and rework the assignment. As there's always an ATU entry for
config space, let's assign index 0 to config space. Then we assign
memory resources to index 1 and up. Finally, if we have an I/O region
and slots remaining, we assign the I/O region last. If there aren't
remaining slots, we keep the same config and I/O space sharing.

We move all the probe stuff to kthread so that it won't block
the system to go on probing other drivers. But that introduced
a bug that PM calls would not be removed by driver core. As each
platform driver uses the same PM callbacks for all device instances.
So add device_release_driver if it fails to probe devices.

1. support buffer_size set by user
2. support assigned chn
3. support udma read
4. support buffer address set by userspace
Need to update test_pcie and test-pcie-ep-new.
New test command:
1. run ./test-pcie-ep-new 500 1024 chn_num buffer_address both on RC and EP first
Release buffer use dma channel number = chn_num.
if buffer_address = 0
pcie_dma_buffer_address get from DT reserved memory
else
pcie_dma_buffer_address = buffer_address
2. run ./test-pcie 1 1000 1024 1 chn_num on RC
The last "1" means enable PCIe udma read, "0" means write.
RC read from EP use dma channel number = chn_num.
3. run ./test-pcie 2 1000 1024 1 chn_num on EP
EP read from RC with offset = buffer count * buffer size.
4. check version by:
cat /sys/kernel/debug/pcie/pcie_trx | grep version
5. 1024 means set buffer size to 1MB.

tegra_pcie_ep_raise_msi_irq() shifted a signed 32-bit value left by 31

Replace the shift by BIT(), which is well-defined.

[ Upstream commit 655832d12f ]
The legacy PCI interrupt lines need to be enabled using PCIE_APP_IRNEN bits
13 (INTA), 14 (INTB), 15 (INTC) and 16 (INTD). The old code however was
taking (for example) "13" as raw value instead of taking BIT(13). Define
the legacy PCI interrupt bits using the BIT() macro and then use these in
PCIE_APP_IRN_INT.

[ Upstream commit 2dc0a201d0 ]
The interrupt affinity scheme used by this driver is incompatible with
multi-MSI as it implies moving the doorbell address to that of another MSI
group. This isn't possible for multi-MSI, as all the MSIs must have the
same doorbell address. As such it is restricted to systems with a single
CPU.

Commit fc54bae288 ("PCI: iproc: Allow allocation of multiple MSIs")
introduced multi-MSI support with a broken allocation mechanism (it failed
to reserve the proper number of bits from the inner domain). Natural
alignment of the base vector number was also not guaranteed.

[ Upstream commit 3cf5f7ab23 ]
An IRQ handler may be called at any time after it is registered, so
anything it relies on must be ready before registration.
rockchip_pcie_subsys_irq_handler() and rockchip_pcie_client_irq_handler()
read registers in the PCIe controller, but we registered them before
turning on clocks to the controller. If either is called before the clocks
are turned on, the register reads fail and the machine hangs.
Similarly, rockchip_pcie_legacy_int_handler() uses rockchip->irq_domain,
but we installed it before initializing irq_domain.
Register IRQ handlers after their data structures are initialized and
clocks are enabled.
Found by enabling CONFIG_DEBUG_SHIRQ, which calls the IRQ handler when it
is being unregistered. An error during the probe path might cause this
unregistration and IRQ handler execution before the device or data
structure init has finished.

[ Upstream commit 94d2276320 ]
On removing the device, any work item (hv_pci_devices_present() or
hv_pci_eject_device()) scheduled on workqueue hbus->wq may still be running
and race with hv_pci_remove().
This can happen because the host may send PCI_EJECT or PCI_BUS_RELATIONS(2)
and decide to rescind the channel immediately after that.
Fix this by flushing/destroying the workqueue of hbus before doing hbus remove.
