Subject: [PATCH] gpio: regmap: Use generic request/free ops
|
||||||
|
|
||||||
|
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.

Álvaro has submitted a similar patch today. My implementation's impact
|
|

is more limited, but I hadn't gotten around to submitting it yet.
