Subject: [PATCH v2 10/18] dt-bindings: i2c: owl: Convert Actions Semi Owl binding to a schema
Date: Fri, 20 Nov 2020 01:56:04 +0200	[thread overview]
Message-ID: <2521d2e63efcd125a4fe93ee55435f399157ab39.1605823502.git.cristian.ciocaltea@gmail.com> (raw)
In-Reply-To: <cover.1605823502.git.cristian.ciocaltea@gmail.com>

Convert the Actions Semi Owl I2C DT binding to a YAML schema for
enabling DT validation.

Additionally, add a new compatible string corresponding to the I2C
controller found in the S500 variant of the Actions Semi Owl SoCs
family.

-Required properties:

-		      - "actions,s700-i2c" for S700 SoC
-		      - "actions,s900-i2c" for S900 SoC
-- reg               : Offset and length of the register set for the device.
-- #address-cells    : Should be 1.
