[v9] add DSC 1.2 dpu supports

[PATCH v9 2/8] drm/msm/dpu: add DPU_PINGPONG_DSC feature bit for DPU < 7.0.0

Posted by Kuogee Hsieh 2 years, 9 months ago

DPU < 7.0.0 requires the PINGPONG block to be involved during
DSC setting up. Since DPU >= 7.0.0, enabling and starting the DSC
encoder engine was moved to INTF with the help of the flush mechanism.
Add a DPU_PINGPONG_DSC feature bit to restrict the availability of
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
and PINGPONG_SM8150_MASK which is used for all DPU < 7.0 chipsets.

changes in v6:
-- split patches and rearrange to keep catalog related files at this patch

changes in v9:
-- delete add BIT(DPU_PINGPONG_DSC)  to PINGPONG_SDM845_TE2_MASK

changes in v7:
-- rewording commit text as suggested at review comments

This is definitely not in an order. Please keep the changelogs sorted
in way easy for other people to read.
