Hi Prafulla,

Thank you so much for feedback.

So you mean the first patch will have only mvgpio.c that enables the support
for gpio for Marvell SoCs and then second patch will enable support for Armada
series via gpio.h file. So if anyone want to use mvgpio.c he/she should write a
compatible version of gpio.h in their arch folder. I hope i am getting your right.

I am finding it difficult to fit this as a macro. so i thought to have it as
inline function in gpio.h will that be ok?
