Hi Chanho and Sam, I am slowly finishing dtschema for Samsung pinctrl drivers [1] and I noticed that Exynos850 and Auto v9 do not define interrupt in pinctrl node with: wakeup-interrupt-controller. This is an interrupt muxing several external wakeup interrupts, e.g. EINT16 - EINT31. For Exynos5433 this looks like: https://elixir.bootlin.com/linux/latest/source/arch/arm64/boot/dts/exynos/exynos5433.dtsi#L857 Missing muxed interrupt for Exynos850 and Autov9 might be fine, although you should see in dmesg error log like: "irq number for muxed EINTs not found" Can you check that your wakeup-interrupt-controller is properly defined in DTSI? If yes, I will need to include such differences in the dtschema. [1] https://github.com/krzk/linux/tree/n/dt-bindings-samsung-pinctrl-schema Best regards, Krzysztof
