As DCVDD will often be supplied by a child node of the MFD, we
can't call mfd_remove_devices as the first step in arizona_dev_exit
as might be expected (tidy up the children before we tidy up the
MFD). We need to disable and put the DCVDD regulator before we call
mfd_remove_devices, to prevent PM runtime from turning this back on we
also need to disable the PM runtime before we do this. Finally we can
not clean up the IRQs until all the MFD children have been removed, as
they may have registered IRQs themselves.
This creates a window of time where the interrupts are enabled but
the PM runtime, on which the IRQ handler depends, is not available,
any interrupts in this window will go unhandled and fill the log with
failed to resume device messages. To avoid this we simply disable the
main IRQ at the start of arizona_dev_exit, we don't need to actually
handle any IRQs in this window as we are removing the driver.

The Arizona CODECs will generally function correctly without a reset line
although it is strongly advised to have one, as such we do allow the system
to boot if the reset gpio is missing or incorrectly specified. However
we should fail probe if we get a probe deferral request, this patch adds
handling for this case.

As runtime PM doesn't function whilst processing system suspend/resume
operations and the Arizona IRQ handlers need runtime PM to function
we must disable IRQs during these operations. Whilst this is
already done in the driver we are using suspend/suspend_late and
resume/resume_noirq to do so which has two problems. Firstly, as
suspend_late is before suspend_noirq that means we still have a
small window where an IRQ can cause issues. Secondly, if another
suspend_late handler fails after ours has run then (as resume_noirq
will not run) we will make unbalanced calls to enable_irq.
This is all simply fixed by using the suspend_noirq callback rather
than suspend_late. Whilst we are doing this tidy the code up a little,
and use the appropriate helper macros.

There are some cases in arizona_dev_init, such as where we don't
recognise the chip ID, in which we head to the error path without
setting a sensible error code in ret. This would lead to the chip
silently failing probe, as it would still return 0. Fix this up by
adding appropriate sets of the return value.
Whilst adding these update the existing paths that do return an error
when the chip is not recognised to use ENODEV, which seems like a better
fit.

This patch adds requesting of the clocks supplied on MCLK1, MCLK2 pins,
gating of the 32k clock is added to the arizona_clk32k_enable(),

It's a temporary change until the CODEC's clock controller gets exposed
through the clk API and is helpful for board configurations where the
MCLK clocks are not provided by always on oscillators.

Pull sound updates from Takashi Iwai:
"There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-related
changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition is
for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It was
initiated by lockdep warning, but resulted in a good cleanup in the
end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP

The function arizona_irq_thread (the threaded handler for the arizona
IRQs) calls pm_runtime_get_sync at the start to ensure that the chip is
active as we handle the IRQ. If the chip is part way through a runtime
suspend when an IRQ arrives the PM core will wait for the suspend to
complete, before resuming. However, since commit 4f0216409f7c
("mfd: arizona: Add better support for system suspend") the runtime
suspend function may call disable_irq, if the chip is going to fully
power off, which will try to wait for any outstanding IRQs to complete.
This results in deadlock as the IRQ thread is waiting for the PM
operation to complete and the PM thread is waiting for the IRQ to
complete.
To avoid this situation we use disable_irq_nosync, which allows the
suspending thread to finish the suspend without waiting for the IRQ to
complete. This is safe because if an IRQ is being processed it can only
be blocked at the pm_runtime_get_sync at the start of the handler
otherwise it wouldn't be possible to suspend.

The PM runtime core by default assumes a chip is suspended when runtime
PM is enabled. Currently the arizona driver enables runtime PM when the
chip is fully active and then disables the DCVDD regulator at the end of
arizona_dev_init. This however has several problems, firstly the if we
reach the end of arizona_dev_init, we did not properly follow all the
proceedures for shutting down the chip, and most notably we never marked
the chip as cache only so any writes occurring between then and the next
PM runtime resume will be lost. Secondly, if we are already resumed when
we reach the end of dev_init, then at best we get unbalanced regulator
enable/disables at work we lose DCVDD whilst we need it.
Additionally, since the commit 4f0216409f7c ("mfd: arizona: Add better
support for system suspend"), the PM runtime operations may
disable/enable the IRQ, so the IRQs must now be enabled before we call
any PM operations.
This patch adds a call to pm_runtime_set_active to inform the PM core
that the device is starting up active and moves the PM enabling to
around the IRQ initialisation to avoid any PM callbacks happening until
the IRQs are initialised.

functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.

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 extcon driver should be able to get its regulator against rather
than against the main arizona device, we must add a supply mapping
allowing the regulator to be located. This patch does so.

The previous update adding MICVDD to the regulator mappings:
mfd: arizona: Add MICVDD to mapped regulators
Only added the mapping for wm5102 and wm5110 but wm8997 also has a
MICVDD supply that needs to be mapped back to the main Arizona device.
