There are 2 banks on it6505, and when writing to different bank,
REG_BANK_SEL needs to be set to the targeted bank. The current code set
this additionally, which causes a race condition when a process is
writing bank 0 registers while another process set the bank to 1. Set
ranges in regmap config so the regmap API would handle the bank changes.

Now that everything that controls which LRU an obj lives in *except* the
backing pages is protected by the LRU lock, add a special path to unpin
in the job_run() path, where we are assured that we already have backing

dma_resv contains the fence that will be signaled when the submit/job

Since the LRU lock is already acquired when moving an obj between LRUs,
we can use it to protect pin_count and madv, without any significant
change in locking (ie. it just expands the scope of the lock by a hand-
ful of instructions). This prepares the way to decrement the pin_count
in the job_run() path without needing to hold the obj lock, to avoid a
potential deadlock (or rather stall) caused by the fence-signaling path
(job_run()) blocking on shrinker/reclaim. (Only a stall because the
wait for fence signaling wait_for_idle() is not infinite.)

We need to use the inuse count to track that a BO is pinned until
we have the hw_fence. But we want to remove the obj lock from the
job_run() path as this could deadlock against reclaim/shrinker
(because it is blocking the hw_fence from eventually being signaled).
So split that tracking out into a per-vma lock with narrower scope.

The flags are only accessed (1) when submit is constructed, before
enqueuing to gpu sched (ie. when still visible to only the task calling
the submit ioctl), (2) here, where we own a reference to the submit and
are serialized on the gpu sched thread, and (3) after the submit is
retired and last reference is dropped, which is serialized on the
submit's reference count. Hence locking is unneeded here.

The DORCR register controls the routing of clocks and data between DU
channels within a group. For groups that contain a single channel,
there's no routing option to control, and some fields of the register
are then reserved. On Gen2 those reserved fields are documented as
required to be set to 0, while on Gen3 and newer the PG1T, DK1S and PG1D
reserved fields must be set to 1.
The DU driver initializes the DORCR register in rcar_du_group_setup(),
where it ignores the PG1T, DK1S and PG1D, and then configures those
fields to the correct value in rcar_du_group_set_routing(). This hasn't
been shown to cause any issue, but prevents certifying that the driver
complies with the documentation in safety-critical use cases.
As there is no reasonable change that the documentation will be updated
to clarify that those reserved fields can be written to 0 temporarily
before starting the hardware, make sure that the registers are always
set to valid values.

The DORCR fields were documented in the R-Car H1 datasheet with 1-based
named, and then got renamed to 0-based in Gen2. The 0-based names are
used for Gen3 and Gen4, making H1 an outlier. Rename the field macros to
make them 0-based, in order to increase readability of the code when
comparing it with the documentation.

The ESCR and OTAR registers are not present in all DU channels on Gen3
SoCs. ESCR only exists in channels that can be routed to an LVDS or
DPAD, and OTAR in channels that can be routed to a DPAD. Skip writing
those registers for other channels. This replaces the DU gen check, as
Gen4 doesn't have LVDS or DPAD outputs.

On R-Car D3 and E3, the LVDS encoder provides the dot (pixel) clock to
the DU, regardless of whether the LVDS output is used or not. When using
the DPAD (RGB) output, the DU driver thus enables and disables the LVDS
PLL manually, while when using the LVDS output, it lets the LVDS bridge
driver handle the PLL configuration internally as part of the atomic
enable and disable operations.
This causes an issue when using the LVDS output. As bridges are disabled
before CRTCs, the current implementation violates the enable/disable
sequences documented in the hardware datasheet, which requires the dot
clock to be enabled before the CRTC is started and disabled after it
gets stopped.
Fix the problem by enabling/disabling the LVDS PLL manually from the DU
regardless of which output is used, and skipping the PLL handling in the
LVDS bridge atomic enable and disable operations.
This is however not enough. Disabling the LVDS encoder while leaving the
PLL on still results in a vertical blanking wait timeout when disabling
the DU. Investigation showed that the culprit is the LVEN bit. For an
unclear reason, clearing the bit when disabling the LVDS encoder blocks
vertical blanking interrupts. We thus have to delay disabling the whole
LVDS encoder, not just disabling the PLL, until the DU is disabled.
We could split the LVDS disable sequence by clearing the LVRES bit in
the LVDS bridge atomic disable handler, and delaying the rest of the
operations, in order to disable the LVDS output at bridge atomic disable
time, before stopping the CRTC. This would make the code more complex,
without a clear benefit, so keep the implementation simple(r).

called from rcar_lvds_pclk_disable(), move the LVDS enable code,
currently stored in the __rcar_lvds_atomic_enable() function, to a
separate code section separate from bridge operations. It will be then
extended with the LVDS disable code.
As part of this rework the __rcar_lvds_atomic_enable() function is

Pull ARM SoC fixes from Arnd Bergmann:
"As usual, most of the bug fixes address issues in the devicetree
files, and out of these, most are for the Qualcomm and NXP platforms,
including:
- A missing 'reserved-memory' property on LG G Watch R that is needed
to prevent clashing with firmware
- Annotations for cache coherency on multiple machines
- Corrections for pinctrl, regulator, clock, iommu and power domain
properties for i.MX and Qualcomm to correctly reflect the hardware
settings
- Firmware file names on multiple machines SA8540P Ride board
- An incompatible change to the qcom vadc driver requires adding
individual labels
- Fix EQoS PHY reset GPIO by dropping the deprecated/wrong property
and switch to the new bindings.
- A fix for PCI bus address translation Tegra194 and Tegra234.
There are also a couple of device driver fixes, addressing:
- A race condition in the amdtee driver
- A performance regression in the Qualcomm 'llcc' driver
- An unitialized variable use NXP i.MX 'weim' driver
- Error handling issues in Qualcomm 'rmtfs', and 'scm' drivers and
the Arm scmi firmware driver"

Earlier merge dropped an if block when applying the patch -
"drm/i915/mtl: Synchronize i915/BIOS on C6 enabling". Bring back the
if block as the check is required by - "drm/i915/mtl: Disable MC6 for MTL
A step" to disable C6 on media for A0 stepping.
Fixes: 3735040978a4 ("drm/i915/mtl: Synchronize i915/BIOS on C6 enabling")

Currently we have no sane way to forcibly disable SAGV, which
makes debugging things a PITA. Manually poking at the pcode
mailbox with it's various SAGV/QGV/PSF formats is no fun,
and likely to be clobbered by the driver anyway.
Let's add a modparam for this.
