-Set the gpiochip request and free ops to the generic implementations.
|
|
|
|
|
-This way a user can provide a gpio-ranges property defined for a pinmux,
|
|
|
|
|
-easing muxing of gpio functions. Provided that the pin controller
|
|
|
|
|
-implementents the pinmux op .gpio_request_enable(), pins will
|
|
|
|
|
-automatically be muxed to their GPIO function when requested.
