Subject: [PATCH] Input: axp20x-pek - allow wakeup after shutdown
|
|
|
|
While the AXP20x PMIC handles the power button itself after shutting
|
|
down, it is not always possible to use the PMIC's built-in shutdown
|
|
feature, such as when other wakeup sources are needed (for example, an
|
|
IR remote or wake-on-LAN) that require firmware support. In that case,
|
|
the PMIC remains on, but suspended, until the board is powered back on.
|
|
|
|
During this "fake" off state, IRQ configuration is similar to system
|
|
sleep, where enable_irq_wake() must be call on an IRQ for it to be
|
|
wakeup capable. Run the suspend callback to arm the power button IRQs
|
|
during the shutdown process, so the power button works in this state.
|
