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.

Commit 8a1861d997 ("w1-gpio: Simplify & get rid of defines") changed
(apparently unknowingly) the driver to a hotpluggable platform-device
driver but did not not update the section markers for probe and remove
(to __devinit/exit, which have since been removed). A later commit fixed
the section mismatch for probe, but left remove marked with __exit.

Pull ARM SoC i.MX DT changes from Olof Johansson:
"This branch contains of devicetree changes for the Freescale i.MX
platform.
The base patch of the branch changes the format of the dts files to a
slightly different format that makes it easier to do derivative board
definitions, but it also introduces a lot of churn in the process
since every line of the file is touched.
On top of that are a handful of the regular changes; enabling more
boards as DT-based instead of legacy board files (mx25pdk), enabling
another driver for devicetree and thus adding bindings (onewire), etc.
I'm not happy about the churn, and will likely not take it for other
platforms in the future."

Convert all uses of devm_request_and_ioremap() to the newly introduced

The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
At the same time, this fixes two faults. First, mdev, the result of
kzalloc, was never freed. Second, on failure of ioremap, 0 was returned.
This has been replaced by -EBUSY, which was the failure value for the call
to request_mem_region, with which the call to ioremap has been combined.
The warning message on failure of ioremap is dropped, because
devm_request_and_ioremap already gives such messages on failure.
Finally, the initial call to platform_get_resource is moved closer to the
call to devm_request_and_ioremap, which takes care of checking whether its
result is NULL, implying that a test on the result of this call to
platform_get_resource is not needed.

If the driver subsystem maintainers want to build test

HDQ/1-wire registers are 32 bits long, even if the register contents
fit into 8 bits, so accesses must be 32-bit aligned. Evidently the
OMAP2/3 interconnects allowed the driver to get away with 8 bit accesses,
but the OMAP4 puts a stop to that:
[ 1.488800] Driver for 1-wire Dallas network protocol.
[ 1.495025] Bad mode in data abort handler detected

The OMAP4430 ES2 Rev X TRM does warn about this restriction in section

Fixes the crash on OMAP4430 ES2 Pandaboard. Tested also on OMAP34xx and
OMAP2420; it seems to work fine on those chips, although due to the lack
of boards with HDQ/1-wire devices here, a more indepth test was not
possible.

Allow the OMAP HDQ1W driver to be built for all OMAP2+ SoCs by
adjusting KConfig dependencies. The previous dependency required
either SOC_OMAP2430 or ARCH_OMAP3 to be set, but the HDQ IP block is
present on OMAP2420 and OMAP44xx SoCs. The driver was still
selectable on multi-OMAP kernel configurations, however; so the
previous prohibition was rather pointless.

The 'mutex' in struct w1_master is use for two very different
purposes.
Firstly it protects various data structures such as the list of all
slaves.
Secondly it protects the w1 buss against concurrent accesses.
This can lead to deadlocks when the ->probe code called while adding a
slave needs to talk on the bus, as is the case for power_supply
devices.
ds2780 and ds2781 drivers contain a work around to track which
process hold the lock simply to avoid this deadlock. bq27000 doesn't
have that work around and so deadlocks.
There are other possible deadlocks involving sysfs.
When removing a device the sysfs s_active lock is held, so the lock
that protects the slave list must take precedence over s_active.
However when access power_supply attributes via sysfs, the s_active
lock must take precedence over the lock that protects accesses to
the bus.
So to avoid deadlocks between w1 slaves and sysfs, these must be
two separate locks. Making them separate means that the work around
in ds2780 and ds2781 can be removed.
So this patch:
- adds a new mutex: "bus_mutex" which serialises access to the bus.
- takes in mutex in w1_search and ds1wm_search while they access
the bus for searching. The mutex is dropped before calling the
callback which adds the slave.
- changes all slaves to use bus_mutex instead of mutex to
protect access to the bus
- removes w1_ds2790_io_nolock and w1_ds2781_io_nolock, and the
related code from drivers/power/ds278[01]_battery.c which
calls them.

This converts the remaining USB drivers in the kernel to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

This fixes a regression in 3.0 reported by Paul Parsons regarding the
removal of the msleep(1) in the ds1wm_reset() function:
: The linux-3.0-rc4 DS1WM 1-wire driver is logging "bus error, retrying"
: error messages on an HP iPAQ hx4700 PDA (XScale-PXA270):
:
: <snip>
: Driver for 1-wire Dallas network protocol.
: DS1WM w1 busmaster driver - (c) 2004 Szabolcs Gyurko
: 1-Wire driver for the DS2760 battery monitor chip - (c) 2004-2005, Szabolcs Gyurko
: ds1wm ds1wm: pass: 1 bus error, retrying
: ds1wm ds1wm: pass: 2 bus error, retrying
: ds1wm ds1wm: pass: 3 bus error, retrying
: ds1wm ds1wm: pass: 4 bus error, retrying
: ds1wm ds1wm: pass: 5 bus error, retrying
: ...
:
: The visible result is that the battery charging LED is erratic; sometimes
: it works, mostly it doesn't.
:
: The linux-2.6.39 DS1WM 1-wire driver worked OK. I haven't tried 3.0-rc1,
: 3.0-rc2, or 3.0-rc3.
This sleep should not be required on normal circuitry provided the
pull-ups on the bus are correctly adapted to the slaves. Unfortunately,
this is not always the case. The sleep is restored but as a parameter to
the probe function in the pdata.
