The Cirrus Logic Madera codecs are a family of related codecs with
extensive digital and analogue I/O, digital mixing and routing,
signal processing and programmable DSPs. This patch adds common
support code shared by all Madera codecs.

This patch also adds the pdata to the parent mfd pdata struct.
Since there is a circular build dependency it's convenient to
patch them both atomically.

The rt5677 driver writes to the IRQ control register within the IRQ
handler in order to flip the polarity of the interrupts that have been
signalled.  If an interrupt fires in the interval between the
regmap_read and the regmap_write, it will not trigger a new call to
rt5677_irq.

Add a bounded loop to rt5677_irq that keeps checking interrupts until
none are seen, so that any interrupts that are signalled in that
interval are correctly handled.

The rt5677 jack detection function has a requirement that the polarity
of an interrupt be flipped after it fires in order to clear the
interrupt.

This patch implements an irq_chip with irq_domain directly instead of
using regmap-irq, so that interrupt source line polarities can be
flipped in the irq handler.

The reason that this patch does not add this feature within regmap-irq
is that future patches will add hotword detection support to this irq
handler. Those patches will require adding additional logic that would
not make sense to have in regmap-irq.

The rt5677 driver uses ACPI-style property names to read from the

When we call snd_soc_component_set_jack(component, NULL, NULL) we should
set rt274->jack to passed jack, so when interrupt is triggered it calls
snd_soc_jack_report(rt274->jack, ...) with proper value.

This fixes problem in machine where in register, we call
snd_soc_register(component, &headset, NULL), which just calls
rt274_mic_detect via callback.
Now when machine driver is removed "headset" will be gone, so we
need to tell codec driver that it's gone with:
snd_soc_register(component, NULL, NULL), but we also need to be able
to handle NULL jack argument here gracefully.
If we don't set it to NULL, next time the rt274_irq runs it will call
snd_soc_jack_report with first argument being invalid pointer and there
will be Oops.

Initial commit of the Conexant CX2072X CODEC driver. Some features are
not present.

The CX2072X is a ultra low power stereo audio codec supports I2S/TDM
host interface with EQ, DRC features in playback mode.

Featues of CX2072X codec:

 * Two 24 bits DACs and DACs.
 * Stereo Headphone AMP.
 * 2.8W per channel class-D output.
 * Integrated seven bands per channel EQ and DRC.
 * Fully integrated headset support with detect/switch.
 * Stereo digital microphone for array applications.
 * S/PDIF output.
 * Bi-directional GPIOs.
 * Support analog and digital PC Beeep.
 * One headset button support.
 * Supports a wide variety of host interfaces.
   -wide variety of I2S and similar bit-stream formats
    with word lengths of up to 24 bits.
   -TDM stream supports up to 4 channels.
 * AEC loopback support.

Further fixes by tiwai:
 * Rebase to 5.2+
 * Missing DAPM entry definitions
 * Missing power hooks
 * Fix uninitialized variable warning
 * Rewrite jack detection stuff to use set_jack callback
 * Plumbing jack detection code for Intel ASoC
 * Move clk management into runtime PM
 * Drop incorrect regcache usages
 * Drop untested stuff: OF table, EQ/DRC handling
 * Lots of code cleanups and minor refactoring

The OF code was dropped due to the lack of testability.
It should be easy to re-add once if someone can test it.

v1->v2: No change
v2->v3: Move register tables to appropriate place
	Remove some confusing codes
	Set snd_ctl_boolean_* helpers directly
	Fix EQ put callback
	Rename to "DAC1 Switch" from "DAC1 Mute Switch"
	Drop superfluous regmap calls at shutdown
	Avoid regmap_register_patch()
	Add missing register definitions
	Fix register access on big-endian machine
	Remove regcache messes
v3->v4: Fix the wrong endianess conversion in reg write
	Minor code cleanups
v4->v5: Move clk management to runtime PM
	Sparse warning fixes
	Some more code simplification
	Drop tricky regcache fiddling
	Apply mutex locks around possible racy sequences
	Move exported jack detection stuff into set_jack callback
v5->v6: Drop buggy&untested EQ and DRC codes
	Lots of code reduction/cleanup
	Add more comments about platform-specific stuff
