pda_power: Add support for using otg transceiver events

2011-08-19T17:03:22+00:00

If the platform data sets the use_otg_notifier flag,
the driver will now register an otg notifier callback and listen
to transceiver events for AC/USB plug-in events instead. This would
normally be used by not specifying is_xx_online callbacks and
not specifying any irqs so the state machine is completely driven
from OTG xceiver events.

pda_power: Add function callbacks for suspend and resume

2010-04-16T15:14:34+00:00

Add function prototypes for power management events so they can be
handled and used by platform implementations.

pda_power: Add optional OTG transceiver and voltage regulator support

2009-02-02T17:15:47+00:00

This patch allows machines to use an OTG transceiver driver instead of
supplying a custom is_usb_online callback to check USB power.
Also, in the case that the OTG transceiver handles charger control when
connected to USB, a regulator named "ac_draw" can be supplied instead of
the custom set_charge callback to control the charger when connected to
AC.

The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in
otg_is_usb_online is probably too simple, I'm just using this with a
peripheral only device and gpio_vbus + bq24022. I'm not sure which other
OTG states can supply power.

pda_power: add init and exit function callbacks

2008-05-02T23:39:55+00:00

This adds init/exit function callbacks to pda_power, to
provide a place where the platform code can request/free
GPIOs that it wants to use in the is_ac_online, is_usb_online
and set_charge functions.

[BATTERY] pda_power platform driver

2007-07-10T10:25:59+00:00

Common power driver for PDAs and phones with one or two external
power supplies (AC/USB) connected to main and backup batteries,
and optional builtin charger.

It's used to stop logic duplication through different embedded
devices. So, power supply *logic* is here. pda_power register
power supplies, and will take care about notifying batteries
about power changes through external power interface.

Currently, power consumption legal limits (including USB power
consumption) should be handled by platform code, inside set_charge
function.
