Instead of always using a function pointer (and initializing it to our
default), just call the default function if the flash didn't set its own
one. That will make the call flow easier to follow.
Also mark the parameter as optional now.

Devices can also be child nodes when we also control that device
through the upstream device (ie, MIPI-DCS for a MIPI-DSI device).
drm_of_find_panel_or_bridge can lookup panel or bridge for a given
device has port and endpoint and it fails to lookup if the device
has a child nodes.
This patch add support to lookup for a child node of the given parent
that isn't either port or ports.

not has ports and has child panel node.

Arm SCMI firmware interface updates for v5.18
Few main additions include:
- Support for OPTEE based SCMI transport to enable using SCMI service
provided by OPTEE on some platforms
- Support for atomic SCMI transports which enables few SCMI transactions
to be completed in atomic context. This involves other refactoring work
associated with it. It also marks SMC and OPTEE as atomic transport as
the commands are completed once the return.
- Support for polling mode in SCMI VirtIO transport in order to support
atomic operations
- Support for atomic clock operations based on availability of atomic
capability in the underlying SCMI transport
Other changes involves some trace and log enhancements and miscellaneous
bug fixes.

Someone on IRC once asked an innocent enough sounding question: Why
with xf86-video-modesetting is es2gears limited at 120fps.
So I broke out the perfetto tracing mesa MR and took a look. It turns
out the problem was drm_atomic_helper_dirtyfb(), which would end up
waiting for vblank.. es2gears would rapidly push two frames to Xorg,
which would blit them to screen and in idle hook (I assume) call the
DIRTYFB ioctl. Which in turn would do an atomic update to flush the
dirty rects, which would stall until the next vblank. And then the
whole process would repeat.
But this is a bit silly, we only need dirtyfb for command mode DSI
panels. So track in plane state whether dirtyfb is required, and
track in the fb how many attached planes require dirtyfb so that we
can skip it when not required. (Note, mdp4 does not actually have
cmd mode support.)

The kerneldoc for usb_get_dev() and usb_get_intf() says that drivers
should always refcount the references they hold for the usb_device or
usb_interface structure, respectively. But this is an overstatement:
In many cases drivers do not access these references after they have
been unbound, and in such cases refcounting is unnecessary.
This patch updates the kerneldoc for the two routines, explaining when
a driver does not need to increment and decrement the refcount. This
should help dispel misconceptions which might otherwise afflict
programmers new to the USB subsystem.

This cleans out the remaining board files from IXP4xx and
makes it an exclusive device tree subarchitecture without any
special weirdness in arch/arm/mach-ixp4xx.
The biggest noticeable change is the removal of the old PCI
driver and along with that the removal of the special DMA
coherency code and defines and the DMA bouncing.
I tried to convert the IXP4xx to multiplatform on top of
this but it didn't work because IXP4xx wants to be big
endian and multiplatform config creates a problem like
this:
../arch/arm/kernel/head.S: Assembler messages:
../arch/arm/kernel/head.S:94: Error: selected processor does not support `setend be' in ARM mode
I think this is because MULTI_V5 turns on CPUs that cannot
do big endian, and IXP4xx turn on big endian. (It crashes if
I try to boot in little endian mode, sorry. It really wants
to run big endian.)
But before fixing multiplatform we can fix all of this!
The networking patches are dependencies so I am requesting
ACKs from the network maintainers on these.

Samsung pinctrl DTS and driver changes for v5.18
Conversion of Samsung pinctrl bindings to dtschema followed up with
alignment of DTS files to the dtschema.
The entire work consists of three parts but everything should be merged
at once to avoid dtschema check errors:
1. Samsung pinctrl driver change necessary to accept new DTS (driver
depends on node names and this has to be adjusted because of dtschema).
2. Conversion to dtschema which brings requirement of different naming
of the GPIO nodes.
3. DTS commits depending on driver (1) above, which convert all GPIO pin
bank names to new naming, required by dtschema.
This also includes few cleanups around DTS which are here to avoid
any merge conflicts.
The Samsung pinctrl driver changes are backwards compatible. However
the DTS changes (renaming nodes) could cause problems in out-of-tree or
other project implementations of the driver.

store the bo reference. Try to keep both working. The mock_bo is a hack
so we can interface directly with the ttm managers alloc() and free() hooks for

moves, etc.

Remove old RPC implementation and add a new native kernel implementation.
The old implementation uses ARM SMC API to issue RPC calls to ARM Trusted
Firmware which provides real implementation of PHY configuration.
But older versions of ARM Trusted Firmware do not provide this PHY
configuration functionality, simply returning: operation not supported; or
worse, some versions provide the configuration functionality incorrectly.
For example the firmware shipped in ESPRESSObin board has this older
version of ARM Trusted Firmware and therefore SATA, USB 3.0 and PCIe
functionality do not work with newer versions of Linux kernel.
Due to the above reasons, the following commits were introduced into Linux,
to workaround these issues by ignoring -EOPNOTSUPP error code from
phy-mvebu-a3700-comphy driver function phy_power_on():
commit 45aefe3d2251 ("ata: ahci: mvebu: Make SATA PHY optional for Armada
3720")
commit 3241929b67d2 ("usb: host: xhci: mvebu: make USB 3.0 PHY optional for
Armada 3720")
commit b0c6ae0f8948 ("PCI: aardvark: Fix initialization with old Marvell's
Arm Trusted Firmware")
Replace this RPC implementation with proper native kernel implementation,
which is independent on the firmware. Never return -EOPNOTSUPP for proper
arguments.
This should solve multiple issues with real-world boards, where it is not
possible or really inconvenient to change the firmware. Let's eliminate
these issues.
This implementation is ported directly from Armada 3720 comphy driver found
in newest version of ARM Trusted Firmware source code, but with various
fixes of register names, some added comments, some refactoring due to the
original code not conforming to kernel standards. Also PCIe mode poweroff
support was added here, and PHY reset support. These changes are also going
to be sent to ARM Trusted Firmware.
[ Pali did the porting from ATF.
I (Marek) then fixed some register names, some various other things,
added some comments and refactored the code to kernel standards. Also
fixed PHY poweroff and added PHY reset. ]

Port number is encoded into argument for SMC call. It is zero for SATA,
PCIe and also both USB 3.0 PHYs. It is non-zero only for Ethernet PHY
(incorrectly called SGMII) on lane 0. Ethernet PHY on lane 1 also uses zero
port number.
So construct "port" bits for SMC call argument can be constructed directly
from PHY type and lane number.
Change driver code to always pass zero port number for non-ethernet PHYs
and for ethernet PHYs determinate port number from lane number. This
simplifies the driver.
As port number from DT PHY configuration is not used anymore, remove whole
driver code which parses it. This also simplifies the driver.

Add check for zero usable stolen memory before calling drm_mm_init
to support configurations where stolen memory exists but is fully

Also skip memory test in cases that usable stolen is smaller than
page size(amount mapped and used to test memory).

- skiping test if available memory is smaller than page size (Lucas)

Checking by >= DISPLAY_VER(12) made sense when the support for Tiger
Lake was added. However now it only leads to wrong behavior when adding
more platforms since it's expected they either don't have DMC to load

wfx_bh_request_tx() send HIF request asynchronously through bh_work().
Then the caller will run wfx_bh_poll_irq() to poll the answer.
However it useless to burn CPU cycles for the polling while the request
has yet been sent. Worse, wfx_bh_poll_irq() may get the CPU and prevent
wfx_bh_request_tx() to run. This problem has been observed on mono core
architecture.

decision making which sja1105_phylink_validate() uses. Remove the now
obsolete sja1105_phylink_validate() implementation to allow DSA to use
