Hi,
What some drivers do when they just get/set a bit in a register to get/set or set the direction of a GPIO, is to select GPIO_GENERIC and just bgpio_init() with the right iomem pointers, then the core will register handlers for get, set, set_direcition callback and get_direction and your driver can just focus on the remainders.
GPIO_GENERIC and bgpio_init() would work for my .set() / .get() callbacks,
not for my .direction_input() / .direction_output() callbacks which need to set more than one register.
If you're not just replacing these with GPIO_GENERIC, please also include a .get_direction() callback.
My .direction_input() and .direction_output() callbacks just call into the pinctrl driver, using pinctrl_gpio_direction_[in,out]put(). I didn't find a way to get the direction info from the pinctrl driver, is that something that the core should provide? Thanks, -Paul
