A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

Allow configuring an optional dedicated wakeirq for gpio-keys that some SoCs have. Let's use the common interrupt naming "irq" and "wakeup" that we already have in use for some drivers and subsystems like i2c framework. Note that the gpio-keys interrupt property is optional. If only a gpio property is specified, the driver tries to translate the gpio into an interrupt. Signed-off-by: Tony Lindgren <tony@atomide.com> --- Changes since v1: - Run make dt_binding_check on the binding - Add better checks for interrupt-names as suggested by Rob, it is now required if two interrupts are configured - Add more decription entries - Add a new example for key-wakeup --- .../devicetree/bindings/input/gpio-keys.yaml | 41 ++++++++++++++++++- 1 file changed, 40 insertions(+), 1 deletion(-)
