^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) - audio-gain-db : audio gain selection for external analog modulation input.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 	Valid values: 0 - 21, step by 3 (rounded down)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 	Default: 0
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) - shutdown-gpios : Specifier of the GPIO connected to SDB pin of the chip.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) Each led is represented as a sub-node of the issi,is31fl319x device.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) There can be less leds subnodes than the chip can support but not more.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) Required led sub-node properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) - reg : number of LED line
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 	Valid values: 1 - number of leds supported by the chip variant.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) Optional led sub-node properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) - label : see Documentation/devicetree/bindings/leds/common.txt.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) - linux,default-trigger :
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) 	see Documentation/devicetree/bindings/leds/common.txt.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) - led-max-microamp : (optional)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 	Valid values: 5000 - 40000, step by 5000 (rounded down)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) 	Default: 20000 (20 mA)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 	Note: a driver will take the lowest of all led limits since the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) 	chip has a single global setting. The lowest value will be chosen
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 	due to the PWM specificity, where lower brightness is achieved
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 	by reducing the dury-cycle of pulses and not the current, which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 	will always have its peak value equal to led-max-microamp.
