Hi Prafulla,

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.
Please give me some suggestion.
Regards,
Ajay Bhargav
