Subject[PATCH] dt-bindings: input: ariel-pwrbutton: use spi-peripheral-props.yaml
Date
Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema. This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.

Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.

While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.a

The binding references also input.yaml and lists explicitly allowed
properties, thus here reference only spi-peripheral-props.yaml for
purpose of documenting the SPI slave device and bringing
spi-max-frequency type validation.

Technically, this depends on [1] merged to SPI tree, if we want to
preserve existing behavior of not allowing SPI CPHA and CPOL in each of
schemas in this patch.

If this patch comes independently via different tree, the SPI CPHA and
CPOL will be allowed for brief period of time, before [1] is merged.
This will not have negative impact, just DT schema checks will be
loosened for that period.
