Currently wakeup is unconditional. After patch 2, even though it's enabled by default, the wakeup source can be disabled by userspace: - enable_irq_wake(axp20x_pek->irq_dbr); + device_init_wakeup(&pdev->dev, true); This is a platform driver for an MFD cell. It does not have its own device tree node. (I see a lot of drivers in drivers/input/misc that generate KEY_POWER, and zero of them reference "wakeup-source". It's a driver for a power button. Being a wakeup source is half the purpose of its existence.) > The AXP288 variant is X86, the other PMIC models are for ARM > (to the best of my knowledge).
