mux: Fix struct mux_state kernel-doc comment

2022-02-04T14:47:12+00:00

A warning is reported because a colon was dropped, it is found by running scripts/kernel-doc, which is caused by using 'make W=1'. drivers/mux/core.c:44: warning: Function parameter or member 'state' not described in 'mux_state' Reported-by: Abaci Robot Signed-off-by: Yang Li Signed-off-by: Peter Rosin Link: https://lore.kernel.org/r/a9a970fc-63f9-5ab9-4983-fba5b01bebe2@axentia.se Signed-off-by: Greg Kroah-Hartman

mux: fix grammar, missing "is".

2022-02-04T14:47:12+00:00

This makes it easier to parse. Signed-off-by: Peter Rosin Link: https://lore.kernel.org/r/75067db8-0264-c49c-daa8-d7a877932711@axentia.se Signed-off-by: Greg Kroah-Hartman

mux: add missing mux_state_get

2022-02-04T14:47:11+00:00

And implement devm_mux_state_get in terms of the new function. Now we have both mux_state_get and mux_state_put as convenient functions ready to be exported should someone ever need unmanaged interfaces.

mux: Add support for reading mux state from consumer DT node

2022-02-04T14:47:11+00:00

In some cases, we might need to provide the state of the mux to be set for the operation of a given peripheral. Therefore, pass this information using mux-states property.

mux: add support for delay after muxing

2021-10-21T19:02:42+00:00

Hardware may require some time for the muxed analog signals to settle after the muxing is changed. Allow users of the mux subsystem to specify this delay with the new mux_control_select_delay() function (and the _try equivalent).

mux: gpio: Simplify code by using dev_err_probe()

2021-04-02T14:28:53+00:00

Use already prepared dev_err_probe() introduced by the commit a787e5400a1c ("driver core: add device probe log helper"). It simplifies EPROBE_DEFER handling.

mux: gpio: Make it OF independent

2021-04-02T14:28:53+00:00

Module doesn't use OF APIs anyhow, make it OF independent by replacing headers and dropping useless of_match_ptr() call. Acked-by: Peter Rosin Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20210330193325.68362-2-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

mux: gpio: Use bitmap API instead of direct assignment

2021-04-02T14:28:53+00:00

Assigning bitmaps like it's done in the driver might be error prone. Fix this by using bitmap API. Acked-by: Peter Rosin Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20210330193325.68362-1-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

mux: adgs1408: Add mod_devicetable.h and remove of_match_ptr

2020-06-29T16:39:44+00:00

Enables probing via the ACPI PRP0001 route but more is mostly about removing examples of this that might get copied into new drivers. Also fixes drivers/mux/adgs1408.c:112:34: warning: unused variable 'adgs1408_of_match as has been reported recently.
