Even though the type of the 'groups' property of a pinmux node is specified as string-array in pinmux-node.yaml, but trying to use multiple strings causes dtbs_check warnings. For example, checking the following dts ... $ cat arch/arm64/boot/dts/marvell/armada-3720-test.dts /dts-v1/; #include "armada-372x.dtsi" &pinctrl_nb { pwm-gpio-pins { groups = "pwm0", "pwm1", "pwm2", "pwm3"; function = "gpio"; }; }; ... results in this warning: arch/arm64/boot/dts/marvell/armada-3720-test.dtb: pinctrl@13800 (marvell,armada3710-nb-pinctrl): pwm-gpio-pins:groups: ['pwm0', 'pwm1', 'pwm2', 'pwm3'] is too long from schema $id: http://devicetree.org/schemas/pinctrl/marvell,armada3710-xb-pinctrl.yaml Add the missing 'items' keyword to the schema to allow using multiple strings without such warnings. Also adjust the indentation of the next statements accordingly.
