New page

The BCM590XX PMU can handle a power-on key (the responsible section is nicknamed PONKEY).

== Key press detection ==

When a key is pressed, the internal IRQ for a key press is raised; when it is released, the internal IRQ for a key release is raised. A driver can interpret these IRQs to toggle a key on/off (in downstream, it's wired up to <code>KEY_POWER</code> by default.

=== Debounce interval ===

A debounce interval can be configured independently for button press and release. The debounce values are 3 bits wide and stored in <code>PONKEYCTRL1</code>.

For the BCM59054/BCM59056, the allowed values are 330ns, 1.2ms, 10ms, 50ms, 100ms, 500ms, 1000ms and 2000ms. For the BCM59039/BCM59042/BCM59055, the allowed values are undocumented, but different from BCM59054/56 - <code>3</code> is equal to 100ms (whereas it's 50ms on 54/56).

== Timer ==

TODO. Seems like it might be possible to control long-press function using a timer (one of "poweroff", "restart" or "smart reset"). [https://github.com/knuxdroid/android_kernel_samsung_baffinlite/blob/cm-12.1/drivers/input/misc/bcmpmu59xxx_ponkey.c#L204-L277 Relevant kernel sources], notably commented out.
