[Freedreno] [v8] drm/msm/disp/dpu1: add support for dspp sub block flush in sc7280

2022-11-09 Thread Kalyan Thota
Flush mechanism for DSPP blocks has changed in sc7280 family, it
allows individual sub blocks to be flushed in coordination with
master flush control.

Representation: master_flush && (PCC_flush | IGC_flush .. etc )

This change adds necessary support for the above design.

Changes in v1:
- Few nits (Doug, Dmitry)
- Restrict sub-block flush programming to dpu_hw_ctl file (Dmitry)

Changes in v2:
- Move the address offset to flush macro (Dmitry)
- Seperate ops for the sub block flush (Dmitry)

Changes in v3:
- Reuse the DPU_DSPP_xx enum instead of a new one (Dmitry)

Changes in v4:
- Use shorter version for unsigned int (Stephen)

Changes in v5:
- Spurious patch please ignore.

Changes in v6:
- Add SOB tag (Doug, Dmitry)

Changes in v7:
- Cache flush mask per dspp (Dmitry)
- Few nits (Marijn)

Changes in v8:
- Few nits (Marijn)
