2009-10-07mfd: pcf50633: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen
Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-10-07power: pcf50633: query charger status directlyPaul Fertser
Current scheme is fragile and is likely to go off sync, especially on batfull->adapter charging automatic MBC transition. Query the status bit every time we need it instead. We need to export another function to query for USB presence because we can't read anything from PCF50633 (via I2C) inside irq context and that is needed by usb gadgets. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-10-07power: pcf50633: properly reenable charging when the supply conditions changePaul Fertser
If chgmod == BATFULL, setting chgena has no effect. Datasheet says we need to set resume instead but when autoresume is used resume doesn't work. Clear and set chgena instead. This enables a user to force charging by re-plugging USB even when the charger entered Battery Full mode, might be handy before a long trip. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-10-07power: pcf50633: get rid of charging restart software auto-triggeringPaul Fertser
After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-07-01olpc_battery: Ensure that the TRICKLE bit is checkedAndres Salomon
There are times when the battery is present but trickle charging, and the EC sets only the TRICKLE bit. So we must check for the bit when we're checking the charging/present status. Signed-off-by: Andres Salomon <dilinger@collabora.co.uk> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
2009-07-01olpc_battery: Fix up eeprom read functionAndres Salomon

2009-06-09da9030_battery: Fix race between event handler and monitorMike Rapoport
There are cases when charging monitor and the event handler try to change the charger state simultaneously. For instance, a charger is connected to the system, there's the detection event and the event handler tries to enable charging. It is possible that the periodic charging monitor runs at the same time and it still thinks there's no external charger. So it tries to disable the charging. As the result, even if the conditions necessary to charge the battery hold, there will be no actual charging. The patch changes the event handler so that instead of enabling/ disabling the charger immediately it would rather make the monitor run. The monitor code then decides what should be the charger state.

2009-02-02pda_power: Add optional OTG transceiver and voltage regulator supportPhilipp Zabel
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>

This patch adds support for the PMU provided by the WM8350 which implements battery, line and USB supplies including a battery charger. The hardware functions largely autonomously, with minimal software control required to initiate fast charging. Support for configuration of the USB supply is not yet implemented. This means that the hardware will remain in the mode configured at startup, by default limiting the current drawn from USB to 100mA.

2008-10-20x86: sysfs: kill owner field from attributeParag Warudkar
Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.
