drm/msm: add support for A750 GPU

Add support for the A750 GPU found on the SM8650 platform

Unlike the the very close A740 GPU on the SM8550 SoC, the A750 GPU
doesn't have an HWCFG block but a separate register set.

The A750 GPU info are added under the adreno_is_a750() macro and
the ADRENO_7XX_GEN3 family id.

drm/msm/a6xx: specify UBWC config for sc7180

Historically the Adreno driver has not been updating memory
configuration registers on a618 (SC7180 platform) implying that the
default configuration is fine. After the rework performed in the commit
8814455a0e54 ("drm/msm: Refactor UBWC config setting") the function
a6xx_calc_ubwc_config() still contained this shortcut and did not
calculate UBWC configuration. However the function which now actually
updates hardware registers, a6xx_set_ubwc_config(), doesn't contain such
check.

Rather than adding the check to a6xx_set_ubwc_config(), fill in the
UBWC config for a618 (based on readings from SC7180).

drm/msm/dpu: improve DSC allocation

At DSC V1.1 DCE (Display Compression Engine) contains a DSC encoder.
However, at DSC V1.2 DCE consists of two DSC encoders, one has an odd
index and another one has an even index. Each encoder can work
independently. But only two DSC encoders from same DCE can be paired
to work together to support DSC merge mode at DSC V1.2. For DSC V1.1
two consecutive DSC encoders (start with even index) have to be paired
to support DSC merge mode.  In addition, the DSC with even index have
to be mapped to even PINGPONG index and DSC with odd index have to be
mapped to odd PINGPONG index at its data path in regardless of DSC
V1.1 or V1.2. This patch improves DSC allocation mechanism with
consideration of those factors.

Changes in V6:
-- rename _dpu_rm_reserve_dsc_single to _dpu_rm_dsc_alloc
-- rename _dpu_rm_reserve_dsc_pair to _dpu_rm_dsc_alloc_pair
-- pass global_state to _dpu_rm_pingpong_next_index()
-- remove pp_max
-- fix for loop condition check at _dpu_rm_dsc_alloc()

Changes in V5:
-- delete dsc_id[]
-- update to global_state->dsc_to_enc_id[] directly
-- replace ndx with idx
-- fix indentation at function declaration
-- only one for loop at _dpu_rm_reserve_dsc_single()

Changes in V4:
-- rework commit message
-- use reserved_by_other()
-- add _dpu_rm_pingpong_next_index()
-- revise _dpu_rm_pingpong_dsc_check()

Changes in V3:
-- add dpu_rm_pingpong_dsc_check()
-- for pair allocation use i += 2 at for loop

Changes in V2:
    -- split _dpu_rm_reserve_dsc() into _dpu_rm_reserve_dsc_single() and
       _dpu_rm_reserve_dsc_pair()

drm/msm/dsi: stop calling set_split_display

Since the commit 8b03ad30e314 ("drm/msm/dsi: Use one connector for dual
DSI mode"), the second DSI host in the bonded pair will not be
associated with the encoder and will not get the bridges, thus making
condition in msm_dsi_manager_set_split_display() always false.

Technically that change broke bonded DSI support in the MDP5 driver. But
since nobody complained in the last 5.5 years, it seems that nobody
cares enough.

drm: xlnx: zynqmp_dpsub: Filter interrupts against mask

Filter out status register against the interrupts' mask.

Some events are being reported via DP status register, even if
corresponding interrupts have been disabled. One instance of such event
leads to generation of VBLANK when the driver is in DRM bridge mode,
which in turn results in NULL pointer dereferencing. We should avoid
processing such events in an interrupt handler context.

This problem is less noticeable when the driver operates in DMA mode, as
in this case we have DRM CRTC object instantiated and DRM framework
simply discards unwanted VBLANKs in drm_handle_vblank().

drm: xlnx: zynqmp_dpsub: Make drm bridge discoverable

ZynqMP DPSUB supports 2 input modes: DMA based and live video.

In the first mode, the driver implements CRTC and DP encoder DRM bridge
to model the complete display pipeline. In this case, DRM bridge is
being directly instantiated within the driver, not using any bridge
discovery mechanisms.

In the live video input mode video signal is generated by FPGA fabric
and passed into DPSUB over the connected bus. In this mode driver
exposes the DP encoder as a DRM bridge, expecting external CRTC to
discover it via drm_of_find_panel_or_bridge() or a similar call. This
discovery relies on drm_bridge.of_node being properly set.

Assign device OF node to the bridge prior to registering it. This will
make said bridge discoverable by an external CRTC driver.
