Pull sound updates from Takashi Iwai:
"Mostly many small changes spread as seen in diffstat in sound/*
directory by this update. A significant change in the subsystem level
is the introduction of snd_soc_component, which will help more generic
handling of SoC and off-SoC components.
Also, snd_BUG_ON() macro is enabled unconditionally now due to its
misuses, so people might hit kernel warnings (it's a good thing for
us).

Pull battery updates from Anton Vorontsov:
"Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core
now automatically populates supplied_from hierarchy from the device
tree. With these patches chargers and batteries can now lookup
each other without the board files support shim. Rhyland Klein at
NVIDIA did the work
- New ST-Ericsson ABX500 hwmon driver. The driver is heavily using
the AB85xx core and depends on some recent changes to it, so that
is why the driver comes through the battery tree. It has an
appropriate ack from the hwmon maintainer (i.e. Guenter Roeck).
Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored
the driver
- Final bits to sync AB85xx ST-Ericsson changes into mainline. The
changes touch mfd parts, but these were acked by the appropriate
MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of
the work and lead the submission process.
Minor changes, but still worth mentioning:
- Battery temperature reporting fix for Nokia N900 phones
- Versatile Express poweroff driver moved into drivers/power/reset/
- Tree-wide: use devm_kzalloc() where appropriate
- Tree-wide: dev_pm_ops cleanups/fixes"

Pull regulator updates from Mark Brown:
"The diffstat and changelog here is dominated by Lee Jones' heroic
efforts to sync the ab8500 driver that's been maintained out of tree
with mainline (plus Axel's cleanup work on the results) but there's a
few other things here:
- Axel Lin added regulator_map_voltage_ascend() optimising a common
pattern for drivers using the core code.
- Milo Kim tought the regulator core to handle regulators sharing an
enable GPIO, avoiding the need to do hacks to support such systems.
- Andrew Bresticker added code to handle missing supplies for
regulators more sensibly for device tree systems, reducing the need
for stubbing there.

The Palma device like TPS65913 have the mode mask which is also
used for enable/disable the rails. The mode bits are defined as
00: OFF
01: AUTO
10: ECO
11: Forced PWM
and modes are set accordingly as
REGULATOR_MODE_NORMAL: AUTO
REGULATOR_MODE_IDLE: ECO
REGULATOR_MODE_FAST: PWM
Two issue observed:
1. If client calls following sequence:
regulator_enable(),
regulator_set_mode(FAST),
regulator_disable()
and again the regulator_enable() then the mode is reset
to NORMAL inplace of keeping the mode as FAST.
Fixing this by storing the current mode configured by client
and restoring modes when enable() is called after disable().
2. In following sequence, the regulator get enabled:
regulator_disable()
regulator_set_mode(FAST),
Fixing this by updating new mode in register only if it is
enabled.

This untangles the final bits of the prcmu code from the platform
code:
* The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c
because they are only of local significance.
* u8500_thsens_device goes into the prcmu, because it uses a PRCMU
IRQ that the platform does not see.
* IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data
because the PRCMU does not see it.

We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.

The Arizona button detection circuit is configurable, allowing the system
integrator to program a range of thresholds for the buttons supported on

the buttons to keys in the input subsystem.

ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs
This patch series covers both ASoC and extcon subsystems and fixes an
interaction between the HPDET function and the headphone outputs - we
really shouldn't run HPDET while the headphone is active. The first
patch is a refactoring to make the extcon side easier.
|
|
Running HPDET while the headphone outputs are enabled can disrupt the
operation of HPDET. In order to avoid this HPDET needs to disable the
headphone outputs and ASoC needs to not enable them while HPDET is
running.
Do the ASoC side of this by storing the enable state in the core driver
structure and only writing to the device if a flag indicating that the
accessory detection side is in a state where it can have the headphone
output stage enabled.

Some systems use the audio CODEC to clock a DAI with multiple data lines
in parallel, meaning that bit clocks are only required for a smaller number
of channels than data is sent for. In some cases providing the extra bit
clocks can take the other devices on the audio bus out of spec.
Support such systems by allowing a maximum number of channels to be
specified.

This patch adds support for the tps65090 charger driver. This driver is
responsible for controlling the charger aspect of the tps65090 mfd.
Currently, this mainly consists of turning on and off the charger, but
some features of the charger can be supported through this driver
including:
- Enable Auto Recharge based on Battery voltage
- Fast Charge Safety Timer
- Maximum battery discharge current
- Maximum battery adapter current
- Enable External Charge
- Disable charging termination based on low charger current (supported)
Once the driver is accepted, later patches can add support for the
features above which are not yet supported.
