ed02d3dd18 drm/msm/dpu: drop temp variable from dpu_encoder_phys_cmd_init()
There is no need to assign a result to temp varable just to return it

004be38657 drm/msm/dpu: call dpu_rm_get_intf() from dpu_encoder_get_intf()
There is little sense to get intf index just to call dpu_rm_get_intf()
on it. Move dpu_rm_get_intf() call to dpu_encoder_get_intf() function.

04ada3d838 drm/msm/dpu: inline dpu_encoder_get_wb()
The function dpu_encoder_get_wb() returns controller_id if the
corresponding WB is present in the catalog. We can inline this function
and rely on dpu_rm_get_wb() returning NULL for indices for which the
WB is not present on the device.

dpu_hw_ctl_intf_cfg_v1() by adding dpu_hw_ctl_update_pending_flush_dsc_v1()

625cbb0770 drm/msm/dpu: always clear every individual pending flush mask
There are two tiers of pending flush control, top level and
individual hardware block. Currently only the top level of
flush mask is reset to 0 but the individual pending flush masks
of particular hardware blocks are left at their previous values,
eventually accumulating all possible bit values and typically
flushing more than necessary.
Reset all individual hardware block flush masks to 0 to avoid
accidentally flushing them.

d45be1ccd3 drm/msm/dpu: Introduce PINGPONG_NONE to disconnect DSC from PINGPONG
Disabling the crossbar mux between DSC and PINGPONG currently
requires a bogus enum dpu_pingpong value to be passed when calling
dsc_bind_pingpong_blk() with enable=false, even though the register
value written is independent of the current PINGPONG block.  Replace
that `bool enable` parameter with a new PINGPONG_NONE dpu_pingpong
flag that triggers the write of the "special" 0xF "crossbar
disabled" value to the register instead.

108ff14177 drm/msm/dpu: Guard PINGPONG DSC ops behind DPU_PINGPONG_DSC bit
DPU < 7.0.0 has DPU_PINGPONG_DSC feature bit set to indicate it requires
both dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() to be
executed to complete DSC configuration if DSC hardware block is present.
Hence test DPU_PINGPONG_DSC feature bit and assign DSC related functions
to the ops of PINGPONG block accordingly if DPU_PINGPONG_DSC bit is set.

Changes in v6:
-- split patches, this patch has function handles DPU_PINGPONG_DSC bit

Changes in v9:
-- the original code of assigning dsc related functions to the ops of
   pingpong block without testing the DPU_PINGPONG_DSC feature bit was
   restored back due to rebase error which defeat the purpose of this
   patch. Remove those error code.

Changes in v10:
-- change commit title
-- correct texts at changes in v9

Changes in v12:
-- fixed length too long at Changes in v9

dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() on the
PINGPONG block to DPU < 7.0.0 hardware, as the registers are not
available on DPU 7.0.0 and higher anymore.
Add DPU_PINGPONG_DSC to PINGPONG_SDM845_MASK, PINGPONG_SDM845_TE2_MASK

50883f733c drm/msm/dpu: replace IS_ERR_OR_NULL with IS_ERR during DSC init
Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If
the value is NULL, then the function will return 0 instead of a proper
return code. Moreover dpu_hw_dsc_init() can not return NULL.
Replace the IS_ERR_OR_NULL() call with IS_ERR().

This follows the commit 740828c73a ("drm/msm/dpu: fix error handling
in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but
then the commit f2803ee91a ("drm/msm/disp/dpu1: Add DSC support in
RM") added it for DSC init.

The existing PP_BLK_TE macro has been removed in favour of directly

4a7c38ec7d drm/msm/dpu: Move autorefresh disable from CMD encoder to pingpong
This autorefresh disable logic in the physical command-mode encoder
consumes three callbacks to the pingpong block, and will explode in
unnecessary complexity when the same callbacks need to be called on the
interface block instead to accommodate INTF TE support.  To clean this
up, move the logic into the pingpong block under a disable_autorefresh
callback, replacing the aforementioned three get_autorefresh,
setup_autorefresh and get_vsync_info callbacks.

The same logic will have to be replicated to the interface block when it
receives INTF TE support, but it is less complex than constantly
switching on a "has_intf_te" boolean to choose a callback.
