Subject: [PATCH 062/454] gpio-poweroff: Allow it to work on Raspberry Pi
|
|
|
|
The Raspberry Pi firmware manages the power-down and reboot
|
|
process. To do this it installs a pm_power_off handler, causing
|
|
the gpio-poweroff module to abort the probe function.
|
|
|
|
This patch introduces a "force" DT property that overrides that
|
|
behaviour, and also adds a DT overlay to enable and control it.
|
|
|
|
Note that running in an active-low configuration (DT parameter
|
|
"active_low") requires a custom dt-blob.bin and probably won't
|
|
allow a reboot without switching off, so an external inversion
|
|
of the trigger signal may be preferable.
