Besides, the device tree support patches for wakeup-interrupts is not being pursed anymore, since it is now handled in pinctrl driver itself. So it would be better not to include this node. > + > + vemmc_reg: voltage-regulator@0 { > + compatible = "regulator-fixed"; > + regulator-name = "VMEM_VDD_2.8V"; > + regulator-min-microvolt = <2800000>;
