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

The eeprom read function was placing values into the wrong place in
'buf'; we were starting from buf[off], rather than buf[0].Also, the for loop that we were using was much uglier than it needed to
be. This cleans it up a bit.Signed-off-by: Andres Salomon

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.Signed-off-by: Mike Rapoport

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

The battery charger state machine switches into charging mode when
the battery voltage falls below 96% of a battery float voltage. But
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 80%.This work_struct function restarts charging at regular intervals to
make sure the battery doesn't discharge too much.Signed-off-by: Balaji Rao

Signed-off-by: Samuel Ortiz -
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.This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.Signed-off-by: Mark Brown

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.[akpm: remove the ifdef for now]

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().Signed-off-by: Robert Jarzmik
