That's different error. You have clocks documented. To remind: we talk about previous error so only, *only* assigned-clocks. > not match any of the regexes: '^(pru|rtu|txpru)@[0-9a-f]+$', > '^pa-stats@[a-f0-9]+$', 'cfg@[a-f0-9]+$', 'iep@[a-f0-9]+$', > 'interrupt-controller@[a-f0-9]+$', 'mdio@[a-f0-9]+$', > 'memories@[a-f0-9]+$', 'mii-g-rt@[a-f0-9]+$', 'mii-rt@[a-f0-9]+$', > 'pinctrl-[0-9]+' > from schema $id: http://devicetree.org/schemas/soc/ti/ti,pruss.yaml# > /home/danish/workspace/linux-next/arch/arm64/boot/dts/ti/k3-am642-evm.dtb: > icssg@30000000: 'assigned-clock-parents', 'assigned-clocks', 'clocks' do > not match any of the regexes: '^(pru|rtu|txpru)@[0-9a-f]+$', > '^pa-stats@[a-f0-9]+$', 'cfg@[a-f0-9]+$', 'iep@[a-f0-9]+$', > 'interrupt-controller@[a-f0-9]+$', 'mdio@[a-f0-9]+$', > 'memories@[a-f0-9]+$', 'mii-g-rt@[a-f0-9]+$', 'mii-rt@[a-f0-9]+$', > 'pinctrl-[0-9]+' > from schema $id: http://devicetree.org/schemas/soc/ti/ti,pruss.yaml# > /home/danish/workspace/linux-next/arch/arm64/boot/dts/ti/k3-am642-evm.dtb: > icssg@30080000: 'assigned-clock-parents', 'assigned-clocks', 'clocks' do > not match any of the regexes: '^(pru|rtu|txpru)@[0-9a-f]+$', > '^pa-stats@[a-f0-9]+$', 'cfg@[a-f0-9]+$', 'iep@[a-f0-9]+$', > 'interrupt-controller@[a-f0-9]+$', 'mdio@[a-f0-9]+$', > 'memories@[a-f0-9]+$', 'mii-g-rt@[a-f0-9]+$', 'mii-rt@[a-f0-9]+$', > 'pinctrl-[0-9]+' > from schema $id: http://devicetree.org/schemas/soc/ti/ti,pruss.yaml# > /home/danish/workspace/linux-next/arch/arm64/boot/dts/ti/k3-am642-evm.dtb: > icssg@30080000: 'assigned-clock-parents', 'assigned-clocks', 'clocks' do > not match any of the regexes: '^(pru|rtu|txpru)@[0-9a-f]+$', > '^pa-stats@[a-f0-9]+$', 'cfg@[a-f0-9]+$', 'iep@[a-f0-9]+$', I don't understand these, either. All of them have clocks. What are you testing? You add clocks to DTS but not to the binding? What would be the point of that test? Best regards, Krzysztof
