6841f6f9c6 drm/mediatek: gamma: Add support for MT8195 
Now that this driver supports 12-bit LUTs, we can add support for the
DISP_GAMMA found on the MT8195 SoC: add its driver data and compatible.

af0e042e16 drm/mediatek: gamma: Add support for 12-bit LUT 
New SoCs, like MT8195, not only may support bigger lookup tables, but
have got a different register layout to support bigger precision:
support specifying the number of `lut_bits` for each SoC and use it
in mtk_gamma_set_common() to perform the right calculations and add
support for 12-bit gamma lookup tables.

While at it, also reorder the variables in mtk_gamma_set_common()
and rename `lut_base` to `lut0_base` to improve readability.

Newer Gamma IP have got multiple LUT banks: support specifying the
size of the LUT banks and handle bank-switching before programming
the LUT in mtk_gamma_set_common() in preparation for adding support
for MT8195 and newer SoCs.

a6b39cd248 drm/mediatek: De-commonize disp_aal/disp_gamma gamma_set functions 
In preparation for adding a 12-bits gamma support for the DISP_GAMMA
IP, remove the mtk_gamma_set_common() function and move the relevant
bits in mtk_gamma_set() for DISP_GAMMA and mtk_aal_gamma_set() for
DISP_AAL: since the latter has no more support for gamma manipulation
(being moved to a different IP) in newer revisions, those functions
are about to diverge and it makes no sense to keep a common one (with
all the complications of passing common data and making exclusions
for device driver data) for just a few bits.

This commit brings no functional changes.

0d4caaaf61 drm/mediatek: gamma: Enable the Gamma LUT table only after programming 
Move the write to DISP_GAMMA_CFG to enable the Gamma LUT to after
programming the actual table to avoid potential visual glitches during
table modification.

Note:
GAMMA should get enabled in between vblanks, but this requires many
efforts in order to make this happen, as that requires migrating all
of the writes to make use of CMDQ instead of cpu writes and that's
not trivial. For this reason, this patch only moves the LUT enable.
The CMDQ rework will come at a later time.

b998684618 drm/msm/a6xx: Fix up QMP handling 
The commit referenced in the Fixes tag had a couple problems (as
pointed out by Dan):

- qmp_put was never called, resulting in refcnt leaks
- failling to acquire the QMP mailbox on A7xx would not undo the probe
  function properly
- the qmp_put call present in the code was unreachable

Fix all of these issues.

5e05be7826 drm/msm/dsi: free TX buffer in unbind 
If the drm/msm init code gets an error during output modeset
initialisation, the kernel will report an error regarding DRM memory
manager not being clean during shutdown. This is because
msm_dsi_modeset_init() allocates a piece of GEM memory for the TX
buffer, but destruction of the buffer happens only at
msm_dsi_host_destroy(), which is called during DSI driver's remove()
time, much later than the DRM MM shutdown.

To solve this issue, move the TX buffer destruction to dsi_unbind(), so
that the buffer is destructed at the correct time. Note, we also have to
store a reference to the address space, because priv->kms->aspace is
cleared before components are unbound.

7389829f21 drm/i915/dp: Store DSC DPCD capabilities in the connector 
In an MST topology the DSC capabilities are specific to each connector,
retrieved either from the sink if it decompresses the stream, or from a
branch device between the source and the sink in case this branch device
does the decompression. Accordingly each connector needs to cache its
own DSC DPCD and FEC capabilities, along with the AUX device through
which the decompression can be enabled. This patch prepares for that by
storing the capabilities and the DSC AUX device in the connector, for
now these just matching the version stored in intel_dp. The follow-up
patches will convert all users to look up these in the connector instead
of intel_dp, after which the intel_dp copies are removed.

- Rebased on intel_edp_get_dsc_sink_cap() addition in previous patch.

6471da5ee3 drm/rockchip: Fix type promotion bug in rockchip_gem_iommu_map() 
The "ret" variable is declared as ssize_t and it can hold negative error
codes but the "rk_obj->base.size" variable is type size_t.  This means
that when we compare them, they are both type promoted to size_t and the
negative error code becomes a high unsigned value and is treated as
success.  Add a cast to fix this.

3b401e30c2 drm/ttm: Reorder sys manager cleanup step 
With the current cleanup flow, we could trigger a NULL pointer
dereference if there is a delayed destruction of a BO with a
system resource that gets executed on drain_workqueue() call,
as we attempt to free a resource using an already released
resource manager.

Remove the device from the device list and drain its workqueue
before releasing the system domain manager in ttm_device_fini().

Add DT support, by:
  1. Creating a panel bridge from DT, and attaching it to the encoder,
  2. Replacing the custom connector with a bridge connector,
  3. Obtaining clock configuration based on the compatible value.

Note that for now the driver uses a fixed clock configuration selecting
the bus clock, as the current code to select other clock inputs needs
changes to support any other SoCs than SH7724.

shmob_drm_crtc_atomic_{en,dis}able() became just wrappers around

c285aac128 drm: renesas: shmobile: Turn vblank on/off when enabling/disabling CRTC 
The DRM core vblank handling mechanism requires drivers to forcefully
turn vblank reporting off when disabling the CRTC, and to restore the
vblank reporting status when enabling the CRTC.
Implement this using the drm_crtc_vblank_{on,off}() helpers.

Note that drm_crtc_vblank_off() must be called at startup to synchronize
the state of the vblank core code with the hardware, which is initially
disabled.  This is performed at CRTC creation time, requiring vertical
blank initialization to be moved before creating CRTCs.
