[PATCH] dt-bindings: i2c: imx: hardware do not restrict clock-frequency to only 100 and 400 kHz

From: David Heidelberg
Date: Fri Oct 29 2021 - 10:12:02 EST


clock-frequency is only restricted by the upper limit of 400 kHz.

Found with:
$ DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/i2c-imx.yaml make dtbs_check
...
arch/arm64/boot/dts/freescale/imx8mq-librem5-r2.dt.yaml: i2c@30a20000: clock-frequency:0:0: 387000 is not one of [100000, 400000]
From schema: linux/Documentation/devicetree/bindings/i2c/i2c-imx.yaml
...

Fixes: 4bdc44347299 ("dt-bindings: i2c: Convert imx i2c to json-schema")
