Pull battery updates from Anton Vorontsov:
"Four new drivers:
- goldfish_battery:
This is Android Emulator battery driver. Originally from Google,
but Intel folks reshaped it for mainline
- pm2301_charger:
A new driver for ST-Ericsson 2301 Power Management chip, uses
AB8500 battery management core
- qnap-poweroff:
The driver adds poweroff functionality for QNAP NAS boxes
- restart-poweroff:
A generic driver that implements 'power off by restarting'. The
actual poweroff functionality is implemented through a bootloader,
so Linux' task is just to restart the box. The driver is useful on
Buffalo Linkstation LS-XHL and LS-CHLv2 boards. Andrew Lunn worked
on submitting the driver (as well as qnap-poweroff above).
Additionally:
- A lot of fixes for ab8500 drivers. This is a part of efforts of
syncing internal ST-Ericsson development tree with the mainline.
Lee Jones @ Linaro worked on compilation and reshaping these
series.
- New health properties for the power supplies: "Watchdog timer
expire" and "Safety timer expire"
- As usual, a bunch of fixes/cleanups here and there"

Pull pinctrl changes from Linus Walleij:
"These are the main pinctrl changes for the v3.9 merge window. The
most interesting change by far is how the device core grabs pinctrl
default handles avoiding the need to stick boilerplate into driver
consumers.
- Grabbing of default pinctrl handles from the device core. These
are the hunks hitting drivers/base. All is ACKed by Greg, after a
long discussion about different alternatives.
- Some stuff also touches the MFD and ARM SoC trees, this has been
coordinated and ACKed.
- New drivers for:
- The Tegra 114 sub-SoC
- Allwinner sunxi
- New ABx500 driver and sub-SoC drivers for AB8500, AB8505, AB9540
and AB8540.
- Make it possible for hogged pins to enter a sleep mode, and make it
possible for drivers to control that mode.
- Various clean-up, extensions and device tree support to various pin
controllers."

Realtek card reader supports both SD and MS card. According to the
settings of rtsx MFD driver, SD host will be probed before MS host.
If we boot/reboot Linux with SD card inserted, the resetting flow of SD
card will succeed, and the following resetting flow of MS is sure to fail.
Then MS upper-level driver will ask rtsx driver to turn power off. This
request leads to the result that the following SD commands fail and SD card
can't be accessed again.
In this commit, Realtek's SD and MS host driver will check whether the card
that upper driver requesting is the one existing in the slot. If not, Realtek's
host driver will refuse the operation to make sure the exlusive accessing
at the same time.

From Linus Walleij:
Two fixes for broken <mach/id.h> cleanup.
* tag 'for-arm-soc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
mfd: db8500-prcmu: update resource passing
drivers/db8500-cpufreq: delete dangling include
Signed-off-by: Olof Johansson <olof@lixom.net>
When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.
This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.
Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.
Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.
The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

AB8500 GPIO no longer handles its GPIO IRQs. Instead, the AB8500
core driver has taken back the responsibility. Prior to this
happening, the AB8500 GPIO driver provided a set of virtual IRQs
which were used as a pass-through. These virtual IRQs had a base
of MOP500_AB8500_VIR_GPIO_IRQ_BASE, which was passed though pdata.
We don't need to do this anymore, so we're pulling out the
property from the structure.

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.
The failure case is where this unwanted write transfers incorrect data to
a critical register.
This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.

Today the battery recharge is determined with a voltage threshold. This
voltage threshold is only valid when the battery is relaxed. In charging
algorithm the voltage read is the loaded battery voltage and no
compensation is done to get the relaxed voltage. When maintenance
charging is not selected, this makes the recharging condition to almost
immediately activate when there is a discharge present on the battery.
Depending on which vendor the battery comes from this behavior can wear
out the battery much faster than normal.
The fuelgauge driver is responsible to monitor the actual battery
capacity and is able to estimate the remaining capacity. It is better to
use the remaining capacity as a limit to determine when battery should
be recharged.
