Subject: [PATCH v12 05/16] dt: bindings: lp50xx: Introduce the lp50xx family of RGB drivers
Date: Fri, 11 Oct 2019 08:06:46 -0500
Message-ID: <20191011130657.4713-6-dmurphy@ti.com> (raw)
In-Reply-To: <20191011130657.4713-1-dmurphy@ti.com>

Introduce the bindings for the Texas Instruments LP5036, LP5030, LP5024,
LP5018, LP5012 and LP5009 RGB LED device driver.  The LP5036/30/24/18/12/9
can control RGB LEDs individually or as part of a control bank group.
These devices have the ability to adjust the mixing control for the RGB
LEDs to obtain different colors independent of the overall brightness of
the LED grouping.

+* Texas Instruments - LP5009/12/18/24/30/36 RGB LED driver
+
+The LP50XX is multi-channel, I2C RGB LED Drivers that can group RGB LEDs into
+a LED group or control them individually.
+
+The difference in these RGB LED drivers is the number of supported RGB modules.
+
+Required parent properties:
+	- compatible:
+		"ti,lp5009"
+		"ti,lp5012"
+		"ti,lp5018"
+		"ti,lp5024"
+		"ti,lp5030"
+		"ti,lp5036"
+	- reg :  I2C slave address
+		lp5009/12 - 0x14, 0x15, 0x16, 0x17
+		lp5018/24 - 0x28, 0x29, 0x2a, 0x2b
+		lp5030/36 - 0x30, 0x31, 0x32, 0x33
+	- #address-cells : 1
+	- #size-cells : 0
+
+Optional parent properties:
+	- enable-gpios : gpio pin to enable/disable the device.
+	- vled-supply : LED supply
+
+Required child properties:
+	- #address-cells : 1
+	- #size-cells : 0
+	- reg : This is the LED module number.
+	- color : Must be LED_COLOR_ID_MULTI
+	- function : see Documentation/devicetree/bindings/leds/common.txt
+
+Required child properties only is LED modules will be banked:
+	- ti,led-bank : This property denotes the LED module numbers that will
+			be controlled as a single RGB cluster.  Each LED module
+			number will be controlled by a single LED class instance.
+			There can only be one instance of the ti,led-bank
+			property for each device node.
+
+Required grandchildren properties:
+	- reg : A single entry denoting the LED output that controls
+		the monochrome LED.
+	- color : see Documentation/devicetree/bindings/leds/common.txt
+	- led-sources : see Documentation/devicetree/bindings/leds/common.txt
+
+The LED outputs associated with the LED modules are defined in Table 1 of the
+corresponding data sheets.
+
+LP5009 - 3 Total RGB cluster LED outputs 0-2
+LP5012 - 4 Total RGB cluster LED outputs 0-3
+LP5018 - 6 Total RGB cluster LED outputs 0-5
+LP5024 - 8 Total RGB cluster LED outputs 0-7
+LP5030 - 10 Total RGB cluster LED outputs 0-9
+LP5036 - 12 Total RGB cluster LED outputs 0-11
+
+Optional child properties:
+	- label : see Documentation/devicetree/bindings/leds/common.txt
+	- linux,default-trigger :
+	   see Documentation/devicetree/bindings/leds/common.txt
