[Intel-gfx] [PATCH v7 5/8] drm/i915/vdsc: Add function to write in PPS register
Suraj Kandpal
suraj.kandpal at intel.com
Tue Aug 8 08:11:32 UTC 2023
Now that we have a function that reads any PPS register based
on intel_dsc_pps enum provided lets create a function that can
write on any PPS.
--v2
-Changes need as PPS enum was dropped
-Remove duplicated code in intel_dsc_write_pps_reg [Jani]
--v3
-Use dsc_split instead of num_vdsc_instances [Ankit]
--v5
-Changes to implement the new dsc_reg array variable passing
[Ankit]
--v7
-Pass no of vdsc instances to get_pps_reg [Ankit]
