Subject: [PATCH] dt-bindings: i2c: imx: hardware do not restrict clock-frequency to only 100 and 400 kHz
Git-commit: 51906dd173b2bd3bdd93a899e4ef7fd667a8d2d1
Patch-mainline: v5.16-rc1

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
...
