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.

power_supply: pda_power: Don't request shared IRQs w/ IRQF_DISABLED

2009-01-25T23:09:26+00:00

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.

pda_power: Check and handle return value of set_irq_wake

2008-08-31T22:10:06+00:00

The recent change in commit 2db873211ba47ef704c301f9ecf4a33413a0b649
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().

drivers/power: fix platform driver hotplug/coldplug

2008-07-25T17:53:28+00:00

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf ("platform: prefix MODALIAS
with "platform:"), the platform modalias is prefixed with "platform:".
Add MODULE_ALIAS() to the hotpluggable "power" drivers drivers, to
re-enable auto loading.

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.

pda_power: various cleanups

2008-02-01T23:44:34+00:00

- handle spurious interrupts correctly;
- get rid of pda_power_supplies array, use two variables instead;
- factor out psy_changed() function, it will be used for polling.

pda_power: only register available psu

2008-02-01T23:42:59+00:00

Currently pda-power adds both ac and usb power supply units.
This patch fixes it so that psu are added only if they are enabled.
