[PATCH 1/1] dt-bindings: gpio: gpio-vf610: Add parsing of hogs

[Alexander Stein]

Allow parsing GPIO controller children nodes with GPIO hogs.

This implements the same as commit dfb49cc231a48 ("dt-bindings: gpio:
fsl-imx-gpio: Add parsing of hogs") and reuses the commit message as
well.

But it was suboptimal. Do it like in commit 6c19974d1e83 ("dt-bindings:
gpio: Convert STMPE GPIO to YAML schema"), including also narrower pattern.

Best regards,

Ah, thanks. I wasn't aware it is part of generic dt-schema.
Regarding the narrower pattern: dt-schema still uses the wider one. Is this 
still correct or something which needs to be fixed?

dtschema must have wider pattern as it covers everything, all boards.

If existing DTS fits narrower pattern, make it narrower. It helps
keeping code consistent thus easier to read.
