[PATCH v3 0/2] dt-bindings: gpio: davinci: Convert to json-schema

[PATCH v3 0/2] dt-bindings: gpio: davinci: Convert to json-schema

[Aswath Govindraju]

Convert the davinci GPIO device tree binding documentation to json-schema.
The GPIO hog node names are defined to end with a 'hog' suffix.

All existing GPIO hogs are fixed to follow above naming convention
before changing the binding to avoid dtbs_check warnings.

changes since v2:
- Used gpio-hog.yaml for gpio-hog property
- Added constraints on gpio-hog node name
- Corrected the gpio hog dt node names to align
  with the dt-schema

changes since v1:
- combined the individual compatible properties into one enum
- added maxItems and minItems properties for gpio-line-names and
  interrupts
- updated the description of interrupts property
- removed the description for properties that are general
- updated the pattern property for gpio hog to indicate any sort
  node name based on its usage
- corrected the example wakeup gpio node name

-Davinci/Keystone GPIO controller bindings
-
-Required Properties:
-- compatible: should be "ti,dm6441-gpio": for Davinci da850 SoCs
-			"ti,keystone-gpio": for Keystone 2 66AK2H/K, 66AK2L,
-						66AK2E SoCs
-			"ti,k2g-gpio", "ti,keystone-gpio": for 66AK2G

-			"ti,j721e-gpio", "ti,keystone-gpio": for J721E SoCs
-			"ti,am64-gpio", "ti,keystone-gpio": for AM64 SoCs
-
-- reg: Physical base address of the controller and the size of memory mapped
-       registers.
-
-- gpio-controller : Marks the device node as a gpio controller.
-
-- #gpio-cells : Should be two.
-  - first cell is the pin number
-  - second cell is used to specify optional parameters (unused)
-
-- interrupts: Array of GPIO interrupt number. Only banked or unbanked IRQs are
-	      supported at a time.
-
-- ti,ngpio: The number of GPIO pins supported.
-
-- ti,davinci-gpio-unbanked: The number of GPIOs that have an individual interrupt
-		            line to processor.
-
-- clocks: Should contain the device's input clock, and should be defined as per
-          the appropriate clock bindings consumer usage in,
-
-          Documentation/devicetree/bindings/clock/keystone-gate.txt
-                            for 66AK2HK/66AK2L/66AK2E SoCs or,

-                            for 66AK2G SoCs
-
-- clock-names: Name should be "gpio";
-
-Currently clock-names and clocks are needed for all keystone 2 platforms
-Davinci platforms do not have DT clocks as of now.
-
-The GPIO controller also acts as an interrupt controller. It uses the default
-two cells specifier as described in Documentation/devicetree/bindings/
-interrupt-controller/interrupts.txt.

-Example:
-
-gpio: gpio@1e26000 {

-	interrupts = <42 IRQ_TYPE_EDGE_BOTH 43 IRQ_TYPE_EDGE_BOTH
-		44 IRQ_TYPE_EDGE_BOTH 45 IRQ_TYPE_EDGE_BOTH
-		46 IRQ_TYPE_EDGE_BOTH 47 IRQ_TYPE_EDGE_BOTH
-		48 IRQ_TYPE_EDGE_BOTH 49 IRQ_TYPE_EDGE_BOTH
-		50 IRQ_TYPE_EDGE_BOTH>;
-	ti,ngpio = <144>;
-	ti,davinci-gpio-unbanked = <0>;
