+Analog devices AS3645A device tree bindings
+
+The AS3645A flash LED controller can drive two LEDs, one high current
+flash LED and one indicator LED. The high current flash LED can be
+used in torch mode as well.
+
+Ranges below noted as [a, b] are closed ranges between a and b, i.e. a
+and b are included in the range.
+
+Please also see common.txt in the same directory.
+
+
+Required properties
+===================
+
+compatible : Must be "ams,as3645a".
+reg : The I2C address of the device. Typically 0x30.
+
+
+Required properties of the "flash" child node
+=============================================
+
+flash-timeout-us: Flash timeout in microseconds. The value must be in
+ the range [100000, 850000] and divisible by 50000.
+flash-max-microamp: Maximum flash current in microamperes. Has to be
+ in the range between [200000, 500000] and
+ divisible by 20000.
+led-max-microamp: Maximum torch (assist) current in microamperes. The
+ value must be in the range between [20000, 160000] and
+ divisible by 20000.
+ams,input-max-microamp: Maximum flash controller input current. The
+ value must be in the range [1250000, 2000000]
+ and divisible by 50000.
+
+
+Optional properties of the "flash" child node
+=============================================
+
+label : The label of the flash LED.
+
+
+Required properties of the "indicator" child node
+=================================================
+
+led-max-microamp: Maximum indicator current. The allowed values are
+ 2500, 5000, 7500 and 10000.
+
+Optional properties of the "indicator" child node
+=================================================
+
+label : The label of the indicator LED.
+
+
+Example
+=======
+
+ as3645a@30 {
+ reg = <0x30>;
+ compatible = "ams,as3645a";
+ flash {
+ flash-timeout-us = <150000>;

+* NXP - pca955x LED driver
+
+The PCA955x family of chips are I2C LED blinkers whose pins not used
+to control LEDs can be used as general purpose I/Os. The GPIO pins can
+be input or output, and output pins can also be pulse-width controlled.
+
+Required properties:
+- compatible : should be one of :
+ "nxp,pca9550"
+ "nxp,pca9551"
+ "nxp,pca9552"
+ "nxp,pca9553"
+- #address-cells: must be 1
+- #size-cells: must be 0
+- reg: I2C slave address. depends on the model.
+
+Optional properties:
+- gpio-controller: allows pins to be used as GPIOs.
+- #gpio-cells: must be 2.
+- gpio-line-names: define the names of the GPIO lines
+
+LED sub-node properties:
+- reg : number of LED line.
+ from 0 to 1 for the pca9550
+ from 0 to 7 for the pca9551
+ from 0 to 15 for the pca9552
+ from 0 to 3 for the pca9553
+- type: (optional) either
+ PCA9532_TYPE_NONE
+ PCA9532_TYPE_LED
+ PCA9532_TYPE_GPIO
+ see dt-bindings/leds/leds-pca955x.h (default to LED)
