  • 5bf2b994b   pda_power: Add optional OTG transceiver and voltage regulator support ... Browse Code »

    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.

  • e82374fd1   pda_power: Check and handle return value of set_irq_wake ... Browse Code »

    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().

  • 2f5a5cf93   drivers/power: fix platform driver hotplug/coldplug ... Browse Code »

    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.

  • 5ebf6e6a9   pda_power: clean up irq, timer ... Browse Code »

    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.

  • b2998049c   [BATTERY] pda_power platform driver ... Browse Code »

    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.
