2018-04-30dt-bindings: pwm-backlight: Add PWM delay proprieties.Enric Balletbo i Serra1-0/+6
Hardware needs a delay between setting an initial (non-zero) PWM and enabling the backlight using GPIO. The post-pwm-on-delay-ms specifies this delay in milli seconds. Hardware also needs a delay between disabing the backlight using GPIO and setting PWM value to 0. The pwm-off-delay-ms is this delay in milli seconds.

Use integers (reg property) to tell the number of the LED to the driver instead of the node name. While both of these approaches are currently used by the LED bindings, using integers will require less driver changes for ACPI support. Additionally, it will make possible LED naming using chip and LED node names, effectively making the label property most useful for human-readable names only.

2017-06-27dt-bindings: leds: document new trigger-sources propertyRafał Miłecki1-2/+33
Some LEDs can be related to a specific device(s) described in the DT. This property allows specifying such relations. E.g. USB LED should usually be used to indicate some USB port(s) state. Please note this binding is designed to be generic and not influenced by any operating system design. Linux developers may find "trigger" part a bit confusing since in Linux triggers are separated drivers. It shouldn't define the binding though (we shouldn't add an extra level of indirection).

2015-11-03leds: netxbig: add device tree bindingSimon Guinot1-0/+92
This patch adds device tree support for the netxbig LEDs. This also introduces a additionnal DT binding for the GPIO extension bus (netxbig-gpio-ext) used to configure the LEDs. Since this bus could also be used to control other devices, then it seems more suitable to have it in a separate DT binding.

2015-10-22dt-bindings: move backlight bindings under ledsRob Herring8-0/+242
Backlights are generally a subtype of LEDs at least from a software point of view if not always electrically. Move the bindings from the video directory to underneath the leds dir.

2015-08-28leds: leds-ns2: move LED modes mapping outside of the driverVincent Donnefort1-0/+9
On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO values to LED mode) is different from the one used on other boards supported by the leds-ns2 driver. With this patch the hardcoded mapping is removed from leds-ns2. Now, it must be defined either in the platform data (if an old-fashion board setup file is used) or in the DT node. In order to allow the later, this patch also introduces a modes-map property for the leds-ns2 DT binding.
