9bd0946d5c drm/msm/dp: simplify stream clocks handling 
There is only a single DP_STREAM_PM clock, stream_pixel. Instead of
using a separate dss_module_power instance for this single clock, handle
this clock directly. This allows us to drop several wrapping functions.

17cb153f81 drm/msm/dp: fold dp_power into dp_ctrl module 
The dp_power submodule is limited to handling the clocks only following
previous cleanups. Fold it into the dp_ctrl submodule, removing one
unnecessary level of indirection.

31a01db14b drm/msm/dp: parse DT from dp_parser_get 
It makes little sense to split the submodule get and actual DT parsing.
Call dp_parser_parse() directly from dp_parser_get(), so that the parser
data is fully initialised once it is returned to the caller.

858ddb64f1 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()

51c139615b drm/msm/dsi: stop calling set_split_display 
Since the commit 8b03ad30e3 ("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.

Drop the msm_dsi_manager_set_split_display() completely and stop calling
the set_split_display() KMS callback. Also remove the
msm_dsi::external_bridge field which was only used by the mentioned
function.

891a8d83c1 drm/msm/dsi: drop msm_dsi_device_connected() function 
Since the commit 8f59ee9a57 ("drm/msm/dsi: Adjust probe order") the
DSI hosts are not bound through the component framework if the DSI
driver wasn't attached to the DSI device connected to this host.

Afterwards, if there is no bridge (including the panel bridge) created
for the DSI device then devm_drm_of_get_bridge() will return an error,
also making msm_dsi_manager_ext_bridge_init() and thus DSI modesetting
init fail.

This way there can be no 'unconnected' MSM DSI bridges. Remove the
msm_dsi_device_connected() function.

ef8d8df3cb 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().

e8ef91f14d 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.
