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.

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.

No new drivers this time, but a bunch of fairly big cleanups:
- Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee Jones. In
particular, the debugfs and the sysct interfaces got extended and improved.
- Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
driver, with a much needed module id lookup code improvement.
- The regular wm5102 and arizona cleanups and fixes from Mark Brown.
- Laxman Dewangan extended the palmas APIs in order to implement the palmas
GPIO and rt drivers.
- Laxman also added DT support for the tps65090 driver.
- The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
Darren Hart.
- Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
devices to switch to the new abx500 pin-ctrl driver.
- The max8925 now has device tree and irqdomain support thanks to Qing Xu.
- The recently added rtsx driver got a few cleanups and fixes for a better
card detection code path and now also supports the RTS5227 chipset, thanks
to Wei Wang and Roger Tseng.

The Arizona CODECs contain a haptics module providing vibration feedback
support. Implement basic support for this, providing simple start/stop and
signal magnitude control.
Since the output path for haptics is routed through the CODEC audio routing
it is modelled as a signal generator within ASoC, the haptics driver calls
DAPM to start and stop the output drivers. An appropriate output path must
be configured via ALSA to connect the haptics source to the correct output.

Some other device functions need to integrate with signal sources in the

In order to handle systems which do not use the generic clock API a
simple wrapper for the 32kHz clock domain in the devices is provided.
Once the generic clock API is widely available this code will be moved
over to use that.
For simplicity some WM5102 specific code is included in the core driver,
the effort involved in splitting the device out isn't worth it.
