Hi Prafulla,
I checked datasheet and for most GPIOs, AF1 is given as GPIO but for
few
its not, so adding a glue logic to check for specific GPIOs wont be a
good idea.
That's the reason i thought its good to keep MFP out of this. Please
give suggestions.
correcting my previous message, I meant AF0. adding to this.. I checked Linux kernel source and they are simply validating if gpio number is within max limits so request returns 0.
And you told me to use MAX_MFP instead of using ARMD_MAX_GPIO, but MAX_MFP is defined lesser than the actual number of GPIO e.g. in case of armada100 MAX_MFP is defined 117 whereas max GPIOs are around 123.
I will check and let you know.
