So why complicate the DT bindings by adding support for deprecated properties? 1. Explicitly allowing deprecated properties means new users may be added, 2. Once all in-tree DTS files are converted, the warnings will be gone anyway, 3. Out-of-tree DTB will still work, as it's very unlikely support for the "gpio" suffix can/will be dropped anytime soon, 4. If anyone runs the validator on out-of-tree DTS files, the most probable intention is to fix any detected issues anyway, and the files can be updated, too, 5. If any out-of-tree code or tooling relies on the *-gpio form, it may already be broken. > - spi-cpha: true > - > required: > - compatible > - - cmd-gpios > + > +oneOf: > + - required: > + - cmd-gpio > + - required: > + - cmd-gpios > > additionalProperties: false Gr{oetje,eeting}s, Geert

The definition "gpio_suffixes[] = { "gpios", "gpio" }" shows that both property names "cmd-gpios" and "cmd-gpio" are supported. But currently only "cmd-gpios" is allowed in this yaml, and the name used in mmp2-olpc-xo-1-75.dts is cmd-gpio.
