Subject: [PATCH v3] dt-bindings: i2c: nxp,pnx-i2c: Convert to dtschema
Convert the NXP PNX I2C Controller bindings to DT schema.
Keep only one example in DT schema to remove redundancy.
Reviewed-by: Conor Dooley <conor.dooley@...rochip.com>
Signed-off-by: Animesh Agarwal <animeshagarwal28@...il.com>
---
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.

-
- - 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

-
- - clock-frequency: desired I2C bus clock frequency in Hz, Default: 100000 Hz
