Subject: [PATCH v2 0/7] add DSC 1.2 dpu supports

This series adds the DPU side changes to support DSC 1.2 encoder. This
was validated with both DSI DSC 1.2 panel and DP DSC 1.2 monitor.
The DSI and DP parts will be pushed later on top of this change.
This seriel is rebase on [1], [2] and catalog fixes from [3].

Subject: [PATCH v2 3/7] drm/msm/dpu: add DSC 1.2 hw blocks for relevant chipsets

From: Abhinav Kumar <[email protected]>

Add DSC 1.2 hardware blocks to the catalog with necessary sub-block and
feature flag information. Each display compression engine (DCE) contains
dual hard slice DSC encoders so both share same base address but with
its own different sub block address.

Subject: [PATCH v2 4/7] drm/msm/dpu: add dsc blocks for remaining chipsets in catalog

From: Abhinav Kumar <[email protected]>

In preparation of calling ping-pong DSC related functions only
for chipsets which have such a design add the dsc blocks for the
chipsets for which DSC is present but was not added in the catalog.

Subject: [PATCH v2 2/7] drm/msm/dpu: separate DSC flush update out of interface

Current DSC flush update is piggyback inside dpu_hw_ctl_intf_cfg_v1().
This patch separate DSC flush away from dpu_hw_ctl_intf_cfg_v1() by
adding dpu_hw_ctl_update_pending_flush_dsc_v1() to handle both per
DSC engine and DSC flush bits at same time to make it consistent with
the location of flush programming of other dpu sub blocks.

Subject: [PATCH v2 5/7] drm/msm/dpu: add DPU_PINGPONG_DSC feature PP_BLK and PP_BLK_TE

Legacy DPU requires PP hardware block involved into setting up DSC
data path. This patch add DDPU_PINGPONG_DSC feature bit to both
PP_BLK and PP_BLK_TE so that both dpu_hw_pp_setup_dsc() and
dpu_hw_pp_dsc_enable() will be executed during DSC path setup.

Subject: [PATCH v2 6/7] drm/msm/dpu: save dpu topology configuration

At current implementation, topology configuration is thrown away after
dpu_rm_reserve(). This patch save the topology so that it can be used
for DSC related calculation later.
