Series [v2,01/12] dt-bindings: pinctrl: fsl,imx6ul-pinctrl: Convert i.MX35/5x/6 to YAML | expand

Commit Message

Marek Vasut Oct. 17, 2024, 12:06 a.m. UTC
The IOMUXC controller description is almost identical on i.MX35/5x/6 SoCs,
except for the configuration bits which differ across SoCs. Rename the
fsl,imx6ul-pinctrl.yaml to fsl,imx35-pinctrl.yaml, fill in compatible
strings for the other SoCs and fill in the various bits into desciption.
This way, i.MX35/5x/6 series SoCs can all be converted to DT schema.
Remove the old text DT bindings description.

V2: - Use DT schema to refer to the fsl,imx35-pinctrl.yaml file
    - Special-case the iMX50 compatible string

I expect findings, so V3 is coming anyway, I'll just let it on the ML 
for a bit for those findings to pour in.

Thanks for keeping an eye on this !
