Struct pinctrl_gpio_range
Did you know?
WebHowever “chip b” has different starting offset for the GPIO range and pin range. The GPIO range of “chip b” starts from GPIO number 48, while the pin range of “chip b” starts from 64. We can convert a gpio number to actual pin number using this pin_base. They are mapped in the global GPIO pin space at: chip a: GPIO range : [32 .. 47 ...
