LEDs connected to is31fl319x LED controller chip Required properties: - compatible : Should be any of "issi,is31fl3190" "issi,is31fl3191" "issi,is31fl3193" "issi,is31fl3196" "issi,is31fl3199" "si-en,sn3199". - #address-cells: Must be 1. - #size-cells: Must be 0. - reg: 0x64, 0x65, 0x66, or 0x67. Optional properties: - audio-gain-db : audio gain selection for external analog modulation input. Valid values: 0 - 21, step by 3 (rounded down) Default: 0 - shutdown-gpios : Specifier of the GPIO connected to SDB pin of the chip. Each led is represented as a sub-node of the issi,is31fl319x device. There can be less leds subnodes than the chip can support but not more. Required led sub-node properties: - reg : number of LED line Valid values: 1 - number of leds supported by the chip variant. Optional led sub-node properties: - label : see Documentation/devicetree/bindings/leds/common.txt. - linux,default-trigger : see Documentation/devicetree/bindings/leds/common.txt. - led-max-microamp : (optional) Valid values: 5000 - 40000, step by 5000 (rounded down) Default: 20000 (20 mA) Note: a driver will take the lowest of all led limits since the chip has a single global setting. The lowest value will be chosen due to the PWM specificity, where lower brightness is achieved by reducing the dury-cycle of pulses and not the current, which will always have its peak value equal to led-max-microamp. Examples: fancy_leds: leds@65 { compatible = "issi,is31fl3196"; #address-cells = <1>; #size-cells = <0>; reg = <0x65>; shutdown-gpios = <&gpio0 11 GPIO_ACTIVE_HIGH>; red_aux: led@1 { label = "red:aux"; reg = <1>; led-max-microamp = <10000>; }; green_power: led@5 { label = "green:power"; reg = <5>; linux,default-trigger = "default-on"; }; };
