2015-08-28leds: syscon: Correct check for syscon_node_to_regmap() errorsBjorn Andersson1-2/+2
syscon_node_to_regmap() returns a regmap or an ERR_PTR(). Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
2015-05-11leds: syscon: instantiate from platform deviceLinus Walleij1-85/+85
Currently syscon LEDs will traverse the device tree looking for syscon devices and if found, traverse any subnodes of these to identify matching children and from there instantiate LED class devices. This is not a good use of the Linux device model. Instead we have converted the device trees to add the "simple-mfd" property to the MFD nexi spawning syscon LEDs so that these will appear as platform devices in the system and we can use the proper device probing mechanism.

2014-11-14leds: syscon: handle multiple syscon instancesLinus Walleij1-31/+36
Currently the syscon LED driver will only handle LEDs on the first syscon found in the system. But there can be several of them, so augment the driver to traverse all syscon nodes and check for syscon LEDs on them.

2014-09-26leds: add a driver for syscon-based LEDsLinus Walleij1-0/+166
This makes it possible to create a set of LEDs from a syscon MFD instance, which is lean mean and clean on the ARM reference designs and can replace the Versatile LEDs driver in the long run, as well as other custom syscon LEDs drivers.
