At present dtc produces these warnings when compiling sandbox:
arch/sandbox/dts/test.dtb: Warning (gpios_property): Could not get phandle node for /base-gpios:num-gpios(cell 0) arch/sandbox/dts/test.dtb: Warning (gpios_property): Missing property '#gpio-cells' in node /reset-ctl or bad phandle (referred from /extra-gpios:num-gpios[0])
Both are due to it assuming that the 'num-gpios' property holds a phandle pointing to a GPIO node.
To avoid these warnings, rename the sandbox property so that it does not include the string 'gpios'.
