[PATCH 0/3] drm/msm/dpu: drop _sspp_subblk_offset()

[Dmitry Baryshkov]

Rework dpu_hw_sspp.c to access sblk base address directly rather than
getting the sblk address through indirect function call.

Dmitry Baryshkov (3):
  drm/msm/dpu: drop SSPP's SRC subblock
  drm/msm/dpu: access QSEED registers directly
  drm/msm/dpu: access CSC/CSC10 registers directly

[PATCH 1/3] drm/msm/dpu: drop SSPP's SRC subblock

[Dmitry Baryshkov]

The src_blk declares a lame copy of main SSPP register space. It's
offset is always 0. It's length has been fixed to 0x150, while SSPP's
length is now correct. Drop the src_blk and access SSPP registers
without additional subblock lookup.

[PATCH 2/3] drm/msm/dpu: access QSEED registers directly

[Dmitry Baryshkov]

Stop using _sspp_subblk_offset() to get offset of the scaler_blk. Inline
this function and use ctx->cap->sblk->scaler_blk.base directly.

[PATCH 3/3] drm/msm/dpu: access CSC/CSC10 registers directly

[Dmitry Baryshkov]

Stop using _sspp_subblk_offset() to get offset of the csc_blk. Inline
this function and use ctx->cap->sblk->csc_blk.base directly.

As this was the last user, drop _sspp_subblk_offset() too.

If you are removing the sub block for the source registers and planning 
to use the SSPP's base address, you might as well remove the macro 
DPU_SSPP_SRC and its usage in setup_layer_ops etc. It doesnt make sense 
to check explicity.
