[PATCH v3] dt-bindings: leds: bcm6358: Convert to DT schema

Convert the brcm,bcm6358 to DT schema.

Signed-off-by: Ninad Naik <[email protected]>
---
Changes in v3:
- Revert to unevaluatedProperties: false and drop explicitly listed
standard LED properties.
- Simplify regex by removing redundant 0| condition.

Changes in v2:
- Modify the maintainers list.
- Add maxItems: 1 and removed minimum and maximum in reg property.
- Explicitly list the properties: label, default-state, linux,default-trigger
and active-low
- Change unevaluatedProperties: false to additionalProperties: false

+title: LEDs connected to Broadcom BCM6358 controller
+
+description: |
+  This controller is present on BCM6358 and BCM6368.
+  In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
+  which can either be controlled by software (exporting the 74x164 as spi-gpio.
+  See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or
+  by hardware using this driver.

-LEDs connected to Broadcom BCM6358 controller
-
-This controller is present on BCM6358 and BCM6368.
-In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
-which can either be controlled by software (exporting the 74x164 as spi-gpio.
-See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or
-by hardware using this driver.
-
-Required properties:
-  - compatible : should be "brcm,bcm6358-leds".
-  - #address-cells : must be 1.
-  - #size-cells : must be 0.
-  - reg : BCM6358 LED controller address and size.
-
-Optional properties:
-  - brcm,clk-div : SCK signal divider. Possible values are 1, 2, 4 and 8.
-    Default : 1
-  - brcm,clk-dat-low : Boolean, makes clock and data signals active low.
-    Default : false
-
-Each LED is represented as a sub-node of the brcm,bcm6358-leds device.
-
-LED sub-node required properties:
-  - reg : LED pin number (only LEDs 0 to 31 are valid).
-
-LED sub-node optional properties:
-  - label : see Documentation/devicetree/bindings/leds/common.txt
-  - default-state : see
-    Documentation/devicetree/bindings/leds/common.txt
-  - linux,default-trigger : see
