Support the Video clock controller for SM8750 Qualcomm SoC. It includes
the extended logic for branch clocks with mem_ops which requires the
inverted logic.
Changes in v4:
- Split the changes to remain functional as per suggestion [Konrad]
- add the new struct fields
- add the ECPRI driver
- add the clk-branch.c changes for mem_ops invert
- update the commit text for ecpricc code changes.
- update the logic for mem_enable_invert [Konrad].
- use GENMASK for 'mem_enable_ack_mask' in videocc driver [Konrad]
- Link to v3: https://lore.kernel.org/r/20251024-sm8750-videocc-v2-v3-0-6286bbda3c8e@oss.qualcomm.com
Changes in v3:
- simplify the logic for handling branch mem ops for non-invert
and invert logic [Dmitry]
- Due to the changes in the branch mem ops the ECPRICC which also
requires branch mem ops are updated to align to the new code.
- Update to use new _desc infra and use 'regmap_update_bits' to align for
better readability [Konrad]
- Link to v2: https://lore.kernel.org/r/20250829-sm8750-videocc-v2-v2-0-4517a5300e41@oss.qualcomm.com
Changes in v2:
- Update the commit message for the invert branch mem ops [Dmitry]
- Update the email to 'oss' and also update copyright.
- update the RB-by tag from Rob.
- Link to v1: https://lore.kernel.org/all/20241206-sm8750_videocc-v1-0-5da6e7eea2bd@quicinc.com/
