Subject: [PATCH v3] dt-bindings: i2c: nxp,pnx-i2c: Convert to dtschema
Date: Wed, 20 Mar 2024 14:16:20 +0530
Message-ID: <20240320084623.82248-1-animeshagarwal28@gmail.com>
Precedence: bulk

Convert the NXP PNX I2C Controller bindings to DT schema.
Keep only one example in DT schema to remove redundancy.

Changes in v3:
- Added a missing whitespace character in maintainers.
- Added parent directory in subject prefix.

Changes in v2:
- Changed the file name from nxp,i2c-pnx.yaml to nxp,pnx-i2c.yaml.
- Dropped properties which were already defined in the top level $ref.
- Dropped unused labels in example.

-* NXP PNX I2C Controller
-
-Required properties:
-
- - reg: Offset and length of the register set for the device
- - compatible: should be "nxp,pnx-i2c"
- - interrupts: configure one interrupt line
- - #address-cells: always 1 (for i2c addresses)
- - #size-cells: always 0
-
-Optional properties:
-
- - clock-frequency: desired I2C bus clock frequency in Hz, Default: 100000 Hz
-
-Examples:
-
-	i2c1: i2c@400a0000 {
-		compatible = "nxp,pnx-i2c";
-		reg = <0x400a0000 0x100>;
