On the wm5110 it is important the reset line is held for slightly longer
to ensure the device starts up well. This patch adds a 5mS delay for
this.

Allow the chip to completely power off if we enter runtime suspend and
there is no jack detection active. This is helpful for systems where
system suspend might remove the supplies to the CODEC, without informing
us. Note the powering off is done in runtime suspend rather than system
suspend, because we need to hold reset until the first time DCVDD is
powered anyway (which would be in runtime resume), and we might as well
save the extra power.

The wm5102 uses a custom boot sequence and the standard boot sequence is
disabled. However, the standard boot sequence must be run at least once
after a cold boot (caused by either a hard reset or removal of AVDD).
Unfortunately the register WRITE_SEQUENCER_CTRL_3 is not affected by the
hardware reset. This means if the device has been previously booted but
the AVDD supply has never been removed, arizona_dev_init will reset the
chip but the boot sequence will not run, which can cause numerous
problems. The solution is to manually clear this register and then boot
the chip again, which is what this patch does.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

I noticed the PMIC configuration on 37xx-evm won't actually shut down
the voltages during off-idle. Turns out 37xx-evm needs the AC charger
state transitions disabled like we are doing for SDP and LDP in the
legacy booting case.
Let's fix this for device tree based booting by setting up the quirk
flag based on the compatible flag. And let's also use the existing
define for STARTON_CHG.
Note that SDP and EVM do not have the PMIC clken wired to gate the
the oscillator while LDP has.

The big thing this release has been Liam's addition of topology support
to the core. We've also seen quite a bit of driver work and the
continuation of Lars' refactoring for component support.
- Support for loading ASoC topology maps from firmware, intended to be
used to allow self-describing DSP firmware images to be built which
can map controls added by the DSP to userspace without the kernel
needing to know about individual DSP firmwares.
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring.
- Big refactoring and cleanup serieses for the Wolfson ADSP and TI
TAS2552 drivers.
- Support for TI TAS571x power amplifiers.
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
- Support for x86 systems with RT5650 and Qualcomm Storm.
