2009-02-02pda_power: Add optional OTG transceiver and voltage regulator supportPhilipp Zabel1-0/+2
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. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
2008-05-03pda_power: add init and exit function callbacksPhilipp Zabel1-0/+4
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.

2007-07-10[BATTERY] pda_power platform driverAnton Vorontsov1-0/+31
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.
