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

Why do you need the aliasing of the names? Just to help the typing?
+#define AFBC_MOD_VALID_BITS (AFBC_SIZE_MASK | AFBC_YTR | AFBC_SPLIT | AFBC_SPARSE | AFBC_CBR | AFBC_TILED | AFBC_SC)
The length of the lines are getting a bit too big, maybe follow the style of the code you are removing and split the macro into multiple lines?
