mux: core: fix double get_device()

2018-01-17T08:45:27+00:00

commit aa1f10e85b0ab53dee85d8e293c8159d18d293a8 upstream. class_find_device already does a get_device on the returned device. So the device returned by of_find_mux_chip_by_node is already referenced and we should not reference it again (and unref it on error).

mux: make device_type const

2017-08-29T11:46:35+00:00

Make this const as it is only stored in the type field of a device structure, which is const. Done using Coccinelle. Signed-off-by: Bhumika Goyal Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman

mux: zap mux- prefix from the source files

2017-08-28T15:11:28+00:00

Preserve the module names with Makefile additions. Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman

mux: convert to using %pOF instead of full_name

2017-08-28T15:11:28+00:00

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman

mux: mux-core: unregister mux_class in mux_exit()

2017-07-17T14:38:35+00:00

Fixes an obvious and nasty typo. Fixes: a3b02a9c6591 ("mux: minimal mux subsystem") Signed-off-by: Kuppuswamy Sathyanarayanan Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman

mux: remove the Kconfig question for the subsystem

2017-07-17T14:37:30+00:00

The MULTIPLEXER question in the Kconfig might be confusing and is of dubious value. Remove it. This makes consumers responsible for selecting MULTIPLEXER, which they already do. Signed-off-by: Peter Rosin Reported-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

mux: adg792a: always require I2C support

mux: mmio-based syscon mux controller

2017-06-03T10:29:26+00:00

This adds a driver for mmio-based syscon multiplexers controlled by bitfields in a syscon register range. Signed-off-by: Philipp Zabel Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman

mux: gpio: add mux controller driver for gpio based multiplexers

2017-06-03T10:29:26+00:00

The driver builds a single multiplexer controller using a number of gpio pins. For N pins, there will be 2^N possible multiplexer states. The GPIO pins can be connected (by the hardware) to several multiplexers, which in that case will be operated in parallel.
