Subject[RFC AFBC 05/12] drm/arm/malidp:- Define a common list of AFBC format modifiers supported for DP500, DP550 and DP650
Date
We need to define a common list of format modifiers supported by each of the Mali
display processors. The difference between DP500 from DP550/650 is that DP500
does not support block split mode (ie AFBC_FORMAT_MOD_SPLIT) and DP550 supports
YUV420 with split mode. We noted these special cases by defining MALIDP_DEVICE_AFBC_SUPPORT_SPLIT
and AFBC_SUPPORT_SPLIT_WITH_YUV_420_10 for malidp_hw_regmap.features

Also we have defined a set of meaningful macros to shorten the modifier names
