Broadcom MIPS SoCs have one or two GPIO banks, depending on the number of gpios present: BCM6345 => 16 GPIOs / 1 bank BCM6328 => 32 GPIOs / 1 bank BCM6358 => 40 GPIOs / 2 banks BCM63268 => 52 GPIOs / 2 banks
typedef struct GpioControl { uint32 GPIODirHi; /* 0 */ uint32 GPIODir; /* 4 */ uint32 GPIOioHi; /* 8 */ uint32 GPIOio; /* C */ }
v2: Introduce changes suggested by Simon Glass
