2021-04-02mux: gpio: Simplify code by using dev_err_probe()Andy Shevchenko1-6/+3
Use already prepared dev_err_probe() introduced by the commit a787e5400a1c ("driver core: add device probe log helper"). It simplifies EPROBE_DEFER handling.

2021-04-02mux: gpio: Make it OF independentAndy Shevchenko1-2/+2
Module doesn't use OF APIs anyhow, make it OF independent by replacing headers and dropping useless of_match_ptr() call.

2021-04-02mux: gpio: Use bitmap API instead of direct assignmentAndy Shevchenko1-2/+4
Assigning bitmaps like it's done in the driver might be error prone. Fix this by using bitmap API.

2018-09-13gpiolib: Pass array info to get/set array functionsJanusz Krzysztofik1-1/+2
In order to make use of array info obtained from gpiod_get_array() and speed up processing of arrays matching single GPIO chip layout, that information must be passed to get/set array functions. Extend the functions' API with that additional parameter and update all users. Pass NULL if a user builds an array itself from single GPIOs.

2018-09-13gpiolib: Pass bitmaps, not integer arrays, to get/set arrayJanusz Krzysztofik1-9/+4
Most users of get/set array functions iterate consecutive bits of data, usually a single integer, while processing array of results obtained from, or building an array of values to be passed to those functions. Save time wasted on those iterations by changing the functions' API to accept bitmaps. All current users are updated as well. More benefits from the change are expected as soon as planned support for accepting/passing those bitmaps directly from/to respective GPIO chip callbacks if applicable is implemented.
