Message

Nautiyal, Ankit K Dec. 4, 2024, 9:26 a.m. UTC

Use helpers for source min/max src bpc appropriately for dp mst case and
to limit max_requested_bpc property min/max values. 

Rev2: Drop patch to limit max_requested_bpc based on src DSC bpc
limits. Instead add change to ignore max_requested_bpc if its
too low for DSC.

Rev3: Update patch#1 commit message.

Rev4: Rebase.

Rev5: Address Jani's comment on patch#3.

Rev6: Rebase.

Rev7: Add patch to fix return type for dsc_min/max_src bpc helpers to
int.

Rev8:
-Drop the first patch.
-Refactor helpers for fec support.
-Add patches to refactor pipe_bpp limits and link limits.

Rev9:
-Address review comments.
-Split patch#3 and patch#6 to 2 patches each.
-Rebase.
