Dear Wolfgang,
Thanks for info, I have seen that. But i am not adding support for GPIO commands.
In reference to
+#define GPLR(x) GPIO_REG(BANK_OFF((x) >> 5) + 0x00) +#define GPDR(x) GPIO_REG(BANK_OFF((x) >> 5) + 0x0c) +#define GPSR(x) GPIO_REG(BANK_OFF((x) >> 5) + 0x18) +#define GPCR(x) GPIO_REG(BANK_OFF((x) >> 5) + 0x24) +#define GSDR(x) GPIO_REG(BANK_OFF((x) >> 5) + 0x54) +#define GCDR(x) GPIO_REG(BANK_OFF((x) >> 5) + 0x60)
Please use a C struct to dsescribe the register layout.
I have followed similar way of using GPIO as used by "drivers/gpio/kw_gpio.c" and defined in "include/asm/arch-kirkwood/gpio.h", so actually i am not adding GPIO support rather i wrote functions that are required by the Ethernet and other drivers.
