[PATCH v2 1/4] drm/msm/dpu: remove DPU_DSPP_GC handling in dspp flush

[Abhinav Kumar]

Gamma correction blocks (GC) are not used today so lets remove
the usage of DPU_DSPP_GC in the dspp flush to make it easier
to remove GC from the catalog.

We can add this back when GC is properly supported in DPU with
one of the standard DRM properties.

[PATCH v2 2/4] drm/msm/dpu: remove DPU_DSPP_IGC handling in dspp flush

[Abhinav Kumar]

Inverse gamma correction blocks (IGC) are not used today so lets
remove the usage of DPU_DSPP_IGC in the dspp flush to make it easier
to remove IGC from the catalog.

We can add this back when IGC is properly supported in DPU with
one of the standard DRM properties.

[PATCH v2 3/4] drm/msm/dpu: remove GC related code from dpu catalog

[Abhinav Kumar]

Since Gamma Correction (GC) block is currently unused, drop
related code from the dpu hardware catalog otherwise this
becomes a burden to carry across chipsets in the catalog.

Yes, we should. I thought of it right after sending this. will push a v3

Yes please.  Don't forget to mention that dpu_dspp_sub_blks didn't even
have an igc member describing the block.

[PATCH v2 4/4] drm/msm/dpu: drop DSPP_MSM8998_MASK from hw catalog

[Abhinav Kumar]

Since GC and IGC masks have now been dropped DSPP_MSM8998_MASK
is same as DSPP_SC7180_MASK. Since DSPP_SC7180_MASK is used more
than DSPP_MSM8998_MASK, lets drop the latter.

Fair enough, I'd use the oldest SoC but that'd require many more

This links to v1.  I don't think you should have this here `b4` should
add it when the definitive series is applied to a tree.

Regardless:
