I've fixed it now locally. > are not the ones you need to fix, so just the diff between old and new. Yeah, I ran the command for espresso and then panda for a comparision. The diff is what i worked on, but I have some doubts which I'd like to ask dts/ti/omap/omap4-samsung-espresso7.dtb: /: irled@0: 'anyOf' conditional failed, one must be fixed: 'reg' is a required property 'ranges' is a required property from schema $id: http://devicetree.org/schemas/root-node.yaml# Documentation/devicetree/bindings/leds/irled/gpio-ir-tx.yaml does not say those properties to be required, is the node placed incorrectly? /home/mighty/linux/arch/arm/boot/dts/ti/omap/omap4-samsung-espresso7.dtb: /: pwm@10: 'anyOf' conditional failed, one must be fixed: 'reg' is a required property 'ranges' is a required property from schema $id: http://devicetree.org/schemas/root-node.yaml# Similarly here as well. /home/mighty/linux/arch/arm/boot/dts/ti/omap/omap4-samsung-espresso7.dtb: current-sense-shunt: 'io-channel-ranges' does not match any of the regexes: 'pinctrl-[0-9]+' from schema $id: http://devicetree.org/schemas/iio/afe/current-sense-shunt.yaml# I tried searching the tree for "io-channel-ranges" which has only one example - ste-ux500-samsung-janice.dts. In that dts the node is same as in espresso. Best Regards, Mithil
