[PATCH v2 1/1] dt-bindings: gpio: mpc8xxx: Convert to yaml format

From: Frank Li
Date: Thu May 30 2024 - 12:55:29 EST


Convert binding doc from txt to yaml.

Remove redundated "gpio1: gpio@2300000" example.
Add gpio-controller at example "gpio@1100".

Signed-off-by: Frank Li <Frank.Li@xxxxxxx>

Notes:
Change from v1 to v2
- Add gpio-controller at example "gpio@1100". to fix bot error.
Strangely, I can't reproduce locally.

make dt_binding_check DT_SCHEMA_FILES=fsl,qoriq-gpio.yaml

-* Freescale MPC512x/MPC8xxx/QorIQ/Layerscape GPIO controller
-
-Required properties:
-- compatible : Should be "fsl,<soc>-gpio"
- The following <soc>s are known to be supported:
- mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq,
- ls1021a, ls1043a, ls2080a, ls1028a, ls1088a.
-- reg : Address and length of the register set for the device
-- interrupts : Should be the port interrupt shared by all 32 pins.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
-
-Optional properties:
-- little-endian : GPIO registers are used as little endian. If not
- present registers are used as big endian by default.
-
-Example of gpio-controller node for a mpc5125 SoC:
-
-gpio0: gpio@1100 {
- compatible = "fsl,mpc5125-gpio";
- #gpio-cells = <2>;
- reg = <0x1100 0x080>;
- interrupts = <78 0x8>;
-};
-
-Example of gpio-controller node for a ls2080a SoC:
-

- compatible = "fsl,ls2080a-gpio", "fsl,qoriq-gpio";
- reg = <0x0 0x2300000 0x0 0x10000>;
