Yes, this needs to be used in pinctrl for the relevant pins. The users are not part of this series, as it will probably be in devicetree overlays or maybe future board files. This is an example configuration for mcu_mcan0 that is required to enable support for wakeup from Partial-IO: &mcu_pmx0 { mcu_mcan0_tx_pins_default: mcu-mcan0-tx-pins-default { pinctrl-single,pins = < AM62X_IOPAD(0x034, PIN_OUTPUT, 0) /* (D6) MCU_MCAN0_TX */ >; }; mcu_mcan0_rx_pins_default: mcu-mcan0-rx-pins-default { pinctrl-single,pins = < AM62X_IOPAD(0x038, PIN_INPUT, 0) /* (B3) MCU_MCAN0_RX */ >; }; mcu_mcan0_rx_pins_wakeup: mcu-mcan0-rx-pins-wakeup { pinctrl-single,pins = < AM62X_IOPAD(0x038, PIN_INPUT | WKUP_EN, 0) /* (B3) MCU_MCAN0_RX */ >; }; }; &mcu_mcan0 { pinctrl-names = "default", "wakeup"; pinctrl-0 = <&mcu_mcan0_tx_pins_default>, <&mcu_mcan0_rx_pins_default>; pinctrl-1 = <&mcu_mcan0_tx_pins_default>, <&mcu_mcan0_rx_pins_wakeup>; status = "okay"; }; Best Markus

You cannot add some code without users claiming that "someone, someday might need it". It's just dead code. Best regards, Krzysztof

WKUP_EN is a flag to enable pin wakeup. Any activity will wakeup the SoC in that case. Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com> --- arch/arm64/boot/dts/ti/k3-pinctrl.h | 3 +++ 1 file changed, 3 insertions(+)
