-* Skyworks Solutions, Inc. AAT1290 Current Regulator for Flash LEDs
-
-The device is controlled through two pins: FL_EN and EN_SET. The pins when,
-asserted high, enable flash strobe and movie mode (max 1/2 of flash current)
-respectively. In order to add a capability of selecting the strobe signal source
-(e.g. CPU or camera sensor) there is an additional switch required, independent
-of the flash chip. The switch is controlled with pin control.
-
-Required properties:
-
-- compatible : Must be "skyworks,aat1290".
-- flen-gpios : Must be device tree identifier of the flash device FL_EN pin.
-- enset-gpios : Must be device tree identifier of the flash device EN_SET pin.
-
-Optional properties:
-- pinctrl-names : Must contain entries: "default", "host", "isp". Entries
-		"default" and "host" must refer to the same pin configuration
-		node, which sets the host as a strobe signal provider. Entry
-		"isp" must refer to the pin configuration node, which sets the
-		ISP as a strobe signal provider.
-
-A discrete LED element connected to the device must be represented by a child
-node - see Documentation/devicetree/bindings/leds/common.txt.
-
-Required properties of the LED child node:
-- led-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
-- flash-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
-                       Maximum flash LED supply current can be calculated using
-                       following formula: I = 1A * 162kohm / Rset.
-- flash-max-timeout-us : see Documentation/devicetree/bindings/leds/common.txt
-                         Maximum flash timeout can be calculated using following
-                         formula: T = 8.82 * 10^9 * Ct.
-
-Optional properties of the LED child node:
-- function : see Documentation/devicetree/bindings/leds/common.txt
-- color : see Documentation/devicetree/bindings/leds/common.txt
-- label : see Documentation/devicetree/bindings/leds/common.txt (deprecated)
-
-Example (by Ct = 220nF, Rset = 160kohm and exynos4412-trats2 board with
-a switch that allows for routing strobe signal either from the host or from
-the camera sensor):
-
-#include "exynos4412.dtsi"
-#include <dt-bindings/leds/common.h>
-

-	compatible = "skyworks,aat1290";
-	flen-gpios = <&gpj1 1 GPIO_ACTIVE_HIGH>;
-	enset-gpios = <&gpj1 2 GPIO_ACTIVE_HIGH>;
-
-	pinctrl-names = "default", "host", "isp";
-	pinctrl-0 = <&camera_flash_host>;
-	pinctrl-1 = <&camera_flash_host>;
-	pinctrl-2 = <&camera_flash_isp>;
-
-	camera_flash: led {
-		function = LED_FUNCTION_FLASH;
-		color = <LED_COLOR_ID_WHITE>;
-		led-max-microamp = <520833>;
-		flash-max-microamp = <1012500>;
-		flash-max-timeout-us = <1940000>;
