Commit Message

AngeloGioacchino Del Regno Sept. 10, 2024, 9:01 a.m. UTC
The display IPs in MediaTek SoCs support being interconnected with
different instances of DDP IPs (for example, merge0 or merge1) and/or
with different DDP IPs (for example, rdma can be connected with either
color, dpi, dsi, merge, etc), forming a full Display Data Path that
ends with an actual display.

The final display pipeline is effectively board specific, as it does
depend on the display that is attached to it, and eventually on the
sensors supported by the board (for example, Adaptive Ambient Light
would need an Ambient Light Sensor, otherwise it's pointless!), other
than the output type.

Add support for OF graphs to most of the MediaTek DDP (display) bindings
to add flexibility to build custom hardware paths, hence enabling board
specific configuration of the display pipeline and allowing to finally
migrate away from using hardcoded paths.

+Device Tree Bindings for LED support on MT6323 PMIC
+
+MT6323 LED controller is subfunction provided by MT6323 PMIC, so the LED
+controllers are defined as the subnode of the function node provided by MT6323
+PMIC controller that is being defined as one kind of Muti-Function Device (MFD)
+using shared bus called PMIC wrapper for each subfunction to access remote
+MT6323 PMIC hardware.
+
+For MT6323 MFD bindings see:
+Documentation/devicetree/bindings/mfd/mt6397.txt
+For MediaTek PMIC wrapper bindings see:
+Documentation/devicetree/bindings/soc/mediatek/mediatek,pwrap.yaml
+
+Required properties:
+- compatible : Must be "mediatek,mt6323-led"
+- address-cells : Must be 1
+- size-cells : Must be 0
+
+Each led is represented as a child node of the mediatek,mt6323-led that
+describes the initial behavior for each LED physically and currently only four
+LED child nodes can be supported.
+
+Required properties for the LED child node:
+- reg : LED channel number (0..3)
+
+Optional properties for the LED child node:
+- label : See Documentation/devicetree/bindings/leds/common.txt
+- linux,default-trigger : See Documentation/devicetree/bindings/leds/common.txt
+- default-state: See Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+	mt6323: pmic {
+		compatible = "mediatek,mt6323";
+
+		...
+
+		mt6323led: leds {
+			compatible = "mediatek,mt6323-led";
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			led@0 {
+				reg = <0>;
+				label = "LED0";
+				linux,default-trigger = "timer";
+				default-state = "on";
+			};
+			led@1 {
+				reg = <1>;
+				label = "LED1";
+				default-state = "off";
+			};
+			led@2 {
+				reg = <2>;
+				label = "LED2";
+				default-state = "on";
+			};
