Srivatsa, Anusha Aug. 15, 2019, 8:54 p.m. UTC
DSC engine on ICL supports only 8 and 10 BPC as the input
BPC. But DSC engine in TGL supports 8, 10 and 12 BPC.
Add 12 BPC support for DSC while calculating compression
configuration.

v2: Remove the separate define TGL_DP_DSC_MAX_SUPPORTED_BPC
and use the value directly.(More such defines can be removed
as part of future patches). (Ville)

v3: Use values directly instead of accessing the defines
everytime for min and max DSC BPC.

Hi Anusha,

Could you take a look at these failures and make sure they are not caused by this patch
so I can merge this?
