Hi Prafulla,

I agree that macros make code look smaller and smarter. Now if you see the registers of GPIO they are not in order, I mean i cannot group together particular gpio set. can i do it this way, 

e.g. 
struct armdgpio_gplr_register {
    u32 gplr0;
    u32 gplr1;
    u32 gplr2;
    u8 pad[some_value]; //this padding is going to be big
    u32 gplr3;
}

then while using this particular set i can just use ARMD1_GPLR_BASE ( = ARMD1_GPIO_BASE + GPLR_OFFSET). moreover i am not using all the registers so i define only those register sets which are in use. what you say about this?
