Merge tag 'leds_for_4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds 

Pull LED updates from Jacek Anaszewski:
 "New drivers:

   - add LED support for MT6323 PMIC

   - add LED support for Motorola CPCAP PMIC

  New features and improvements:

   - add LED trigger for all CPUs aggregated which is useful on tiny
     boards with more CPU cores than LED pins

   - add OF variants of LED registering functions as a preparation for
     adding generic support for Device Tree parsing

   - dell-led improvements and cleanups, followed by moving it to the
     x86 platform driver subsystem which is a more appropriate place for
     it

   - extend pca9532 Device Tree support by adding the LEDs
     'default-state' property

   - extend pca963x Device Tree support by adding nxp,inverted-out
     property for inverting the polarity of the output

   - remove ACPI support for lp3952 since it relied on a non-official
     ACPI IDs"

Motorola CPCAP PMIC LEDs

------------------------



This module is part of the CPCAP. For more details about the whole

chip see Documentation/devicetree/bindings/mfd/motorola-cpcap.txt.



Requires node properties:

- compatible: should be one of

   * "motorola,cpcap-led-mdl"		(Main Display Lighting)

   * "motorola,cpcap-led-kl"		(Keyboard Lighting)

   * "motorola,cpcap-led-adl"		(Aux Display Lighting)

   * "motorola,cpcap-led-red"		(Red Triode)

   * "motorola,cpcap-led-green"		(Green Triode)

   * "motorola,cpcap-led-blue"		(Blue Triode)

   * "motorola,cpcap-led-cf"		(Camera Flash)

   * "motorola,cpcap-led-bt"		(Bluetooth)

   * "motorola,cpcap-led-cp"		(Camera Privacy LED)

- label: see Documentation/devicetree/bindings/leds/common.txt

- vdd-supply: A phandle to the regulator powering the LED



Example:



&cpcap {

	cpcap_led_red: red-led {

		compatible = "motorola,cpcap-led-red";

		label = "cpcap:red";

		vdd-supply = <&sw5>;

	};

Device Tree Bindings for LED support on MT6323 PMIC



MT6323 LED controller is subfunction provided by MT6323 PMIC, so the LED

controllers are defined as the subnode of the function node provided by MT6323

PMIC controller that is being defined as one kind of Muti-Function Device (MFD)

using shared bus called PMIC wrapper for each subfunction to access remote

MT6323 PMIC hardware.



For MT6323 MFD bindings see:

Documentation/devicetree/bindings/mfd/mt6397.txt

For MediaTek PMIC wrapper bindings see:

Documentation/devicetree/bindings/soc/mediatek/pwrap.txt



Required properties:

- compatible : Must be "mediatek,mt6323-led"

- address-cells : Must be 1

- size-cells : Must be 0



Each led is represented as a child node of the mediatek,mt6323-led that

describes the initial behavior for each LED physically and currently only four

LED child nodes can be supported.



Required properties for the LED child node:

- reg : LED channel number (0..3)



Optional properties for the LED child node:

- label : See Documentation/devicetree/bindings/leds/common.txt

- linux,default-trigger : See Documentation/devicetree/bindings/leds/common.txt

- default-state: See Documentation/devicetree/bindings/leds/common.txt



Example:



	mt6323: pmic {

		compatible = "mediatek,mt6323";



		...



		mt6323led: leds {

			compatible = "mediatek,mt6323-led";

			#address-cells = <1>;

			#size-cells = <0>;



			led@0 {

				reg = <0>;

				label = "LED0";

				linux,default-trigger = "timer";

				default-state = "on";

			};

			led@1 {

				reg = <1>;

				label = "LED1";

				default-state = "off";

			};

			led@2 {

				reg = <2>;

				label = "LED2";

				default-state = "on";

			};

		};

	};
