dd5e3d8300 drm/msm/dpu: set pdpu->is_rt_pipe early in dpu_plane_sspp_atomic_update() 
[ Upstream commit 1d233b1cb1 ]

The function dpu_plane_sspp_atomic_update() updates pdpu->is_rt_pipe
flag, but after the commit 854f6f1c65 ("drm/msm/dpu: update the qos
remap only if the client type changes") it sets the flag late, after all
the qos functions have updated QoS programming. Move the flag update
back to the place where it happened before the mentioned commit to let
the pipe be programmed according to its current RT/non-RT state.

a52c455600 pinctrl: renesas: rzg2l: Fix configuring the GPIO pins as interrupts 
[ Upstream commit 00dfe29887 ]

On the RZ/G2UL SoC we have less number of pins compared to RZ/G2L and also
the pin configs are completely different. This patch makes sure we use the
appropriate pin configs for each SoC (which is passed as part of the OF
data) while configuring the GPIO pin as interrupts instead of using
rzg2l_gpio_configs[] for all the SoCs.

a64eb25a29 drm/mipi-dsi: Fix byte order of 16-bit DCS set/get brightness 
[ Upstream commit c9d27c6be5 ]

The MIPI DCS specification demands that brightness values are sent in
big endian byte order. It also states that one parameter (i.e. one byte)
shall be sent/received for 8 bit wide values, and two parameters shall
be used for values that are between 9 and 16 bits wide.

Add new functions to properly handle 16-bit brightness in big endian,
since the two 8- and 16-bit cases are distinct from each other.

9e1e236acd drm/msm/dpu: Disallow unallocated resources to be returned 
[ Upstream commit abc40122d9 ]

In the event that the topology requests resources that have not been
created by the system (because they are typically not represented in
dpu_mdss_cfg ^1), the resource(s) in global_state (in this case DSC
blocks, until their allocation/assignment is being sanity-checked in
"drm/msm/dpu: Reject topologies for which no DSC blocks are available")
remain NULL but will still be returned out of
dpu_rm_get_assigned_resources, where the caller expects to get an array
containing num_blks valid pointers (but instead gets these NULLs).

To prevent this from happening, where null-pointer dereferences
typically result in a hard-to-debug platform lockup, num_blks shouldn't
increase past NULL blocks and will print an error and break instead.
After all, max_blks represents the static size of the maximum number of
blocks whereas the actual amount varies per platform.

^1: which can happen after a git rebase ended up moving additions to
_dpu_cfg to a different struct which has the same patch context.

3723c4dbcd drm/msm/dpu: check for null return of devm_kzalloc() in dpu_writeback_init() 
[ Upstream commit 21e9a838f5 ]

Because of the possilble failure of devm_kzalloc(), dpu_wb_conn might
be NULL and will cause null pointer dereference later.

Therefore, it might be better to check it and directly return -ENOMEM.

9aba03fb51 hwmon: (ftsteutates) Fix scaling of measurements 
[ Upstream commit ca8fd8c16a ]

A user complained that the ftsteutates driver was displaying
bogus values since its introduction. This happens because the
sensor measurements need to be scaled in order to produce
meaningful results:
- the fan speed needs to be multiplied by 60 since its in RPS
- the temperature is in degrees celsius and needs an offset of 64
- the voltage is in 1/256 of 3.3V

The offical datasheet says the voltage needs to be divided by 256,
but this is likely an off-by-one-error, since even the BIOS
devides by 255 (otherwise 3.3V could not be measured).

The voltage channels additionally need a board-specific multiplier,
however this can be done by the driver since its board-specific.

The reason the missing scaling of measurements is the way Fujitsu
used this driver when it was still out-of-tree. Back then, all
scaling was done in userspace by libsensors, even the generic one.

Tested on a Fujitsu DS3401-B1.

41286a53e7 drm/vc4: drop all currently held locks if deadlock happens 
[ Upstream commit 479d4f0be4 ]

If vc4_hdmi_reset_link() returns -EDEADLK, it means that a deadlock
happened in the locking context. This situation should be addressed by
dropping all currently held locks and block until the contended lock
becomes available. Currently, vc4 is not dealing with the deadlock
properly, producing the following output when PROVE_LOCKING is enabled:
