-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 one of
-  - "mediatek,mt6323-led"
-  - "mediatek,mt6331-led"
-  - "mediatek,mt6332-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

+description: |
+  MT6397/MT6323 is a power management system chip.
+  Please see the sub-modules below for supported features.
+
+  MT6397/MT6323 is a multifunction device with the following sub modules:
+  - Regulators
+  - RTC
+  - ADC
+  - Audio codec
+  - GPIO
+  - Clock
+  - LED
+  - Keys
+  - Power controller
+
+  It is interfaced to host controller using SPI interface by a proprietary hardware
+  called PMIC wrapper or pwrap. MT6397/MT6323 PMIC is a child device of pwrap.
+  See the following for pwrap node definitions:
