Axel Lin 300bac7fb8 power_supply: Convert drivers/power/* to use module_platform_driver()
This patch converts the drivers in drivers/power/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Dima Zavin 9ad63986c6 pda_power: Add support for using otg transceiver events
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.

Philipp Zabel 5bf2b994bf pda_power: Add optional OTG transceiver and voltage regulator support
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.

Philipp Zabel 74194cc710 power_supply: pda_power: Don't request shared IRQs w/ IRQF_DISABLED
IRQF_DISABLED is not guaranteed for shared IRQs. I think power_changed_isr
doesn't need it anyway, as it only fires a timer.
This patch enables IRQF_SAMPLE_RANDOM instead.

Robert Jarzmik e82374fd1a pda_power: Check and handle return value of set_irq_wake
The recent change in commit 2db873211b
forces the calls enable_irq_wake() and disable_irq_wake() to
be balanced. But if in pda_power_suspend() the call to
enable_irq_wake() fails (because attached gpio cannot wake
up the CPU), the corresponding disable_irq_wake will WARN().
Fix it by storing success/failure of enable_irq_wake().

Jeff Garzik 5ebf6e6a96 pda_power: clean up irq, timer
Clean up pda_power interrupt handling:

Prior to this patch, the driver would pass information it needed
to the interrupt handler dev_id pointer, and then prompt forget it
ever did so, recreating that same information after a couple passes
through the timer-based state machine.

This patch removes the redundant checks by passing the
pda_power_supply[] pointer through the state machine.  The current
code passed 'irq' through the state machine, as an index to recreate
the pointer, when we could more simply pass around the pointer itself.

This patch makes it easier to remove the 'irq' argument in the future,
in addition to cleaning up the driver today.

Anton Vorontsov b2998049cf [BATTERY] pda_power platform driver
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.
