* Unlike other drivers, a GPIO controller's internal data is created and set by gpio_controller_init_descriptors()
|
|
* This means that the specific controller implementation cannot set the device's driver data, as it's already set by the GPIO controller base coded.
|
|
* When calling init descriptors, the caller can pass a controller_context, which is an optional pointer that holds the implementation's internal data.
