Since they were defined to index the array ssi->regvals[2], this patch moves these two macros to fsl_ssi.c, closer to its owner ssi->regvals. And it also puts some comments here to limit their value within [0, 1]. Signed-off-by: Nicolin Chen Tested-by: Caleb Crome Tested-by: Maciej S. Szmigiero Reviewed-by: Maciej S.
