What is your suggestion about this line? Just NOT change it? Or adding a new file imx8mm-reset.h but still use the IMX8MQ_RESET_ as prefix ? Or keep what I changed, but adding some comments in those macros that i.MX8MM does NOT support? Thanks, Anson. > > regards > Philipp

I would prefer to add an imx8mm-reset.h with only the existing reset bits, using the IMX8MM_RESET_ prefix. That would make it easy to spot errors in the dtsi (anything starting with IMX8MQ_ is potentially wrong). > Just NOT change it? The change is good in principle. It just should point to an imx8mm- reset.h with only the existing resets on i.MX8MM, or imx8mq-reset.h should be modified to actually make clear which resets are valid on i.MX8MM. > Or adding a new file imx8mm-reset.h but still use the IMX8MQ_RESET_ as > prefix ? I don't think you should redefine the same macros in imx8mm-reset.h. In this case using IMX8MM_RESET_ would be better. > Or keep what I changed, but adding some comments in those macros that > i.MX8MM does NOT support? That would be acceptable as well. regards Philipp
