This is a representation of the OpenISA GPIO nodes
dts/bindings: Move common properties into a base.yaml Move common properties like 'compatible', 'reg', 'reg-names', 'interrupts', 'interrupt-names', and 'label' into one common base.yaml that all the other yaml's can inherit from. This removes both duplication and inconsistent definition. The device specific yamls just need to say if a property is 'required' or not. NOTE: due to some generation conflicts we did not covert 'soc-nv-flash.yaml' to use base.yaml. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

dts: Add base gpio-controller to dts bindings Introduce a gpio.yaml that GPIO controller bindings should inherit from. gpio.yaml defines the properties "gpio-controller" and "#gpio-cells" which all gpio controllers should have. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

dts/bindings: use const to validate #<FOO>-cells In most cases #<FOO>-cells should be a constant. For example in spi controller #address-cells should be 1, and #size-cells should be 0. Use the const attribute to specify such single known values. Add const value to missing bindings which have cells. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
