Fabio Estevam 937e92dc50 ASoC: wm8962: Adjust clk definitions so that simple card can work
When trying to use simple card with wm8962 the following probe
error happens:

wm8962 0-001a: simple-card: set_sysclk error
asoc-simple-card sound: ASoC: failed to init 202c000.ssi-wm8962: -22
asoc-simple-card sound: ASoC: failed to instantiate card -22
asoc-simple-card: probe of sound failed with error -22

In simple-card.c the snd_soc_dai_set_sysclk() function is called with
clk_id as 0, which is an invalid clock for wm8962.

Adjust the clocks source definitions in wm8962.h so that the
simple card driver can work successfully.

Charles Keepax 44330ab516 ASoC: wm8962: Update register CLASS_D_CONTROL_1 to be non-volatile
The register CLASS_D_CONTROL_1 is marked as volatile because it contains
a bit, DAC_MUTE, which is also mirrored in the ADC_DAC_CONTROL_1
register. This causes problems for the "Speaker Switch" control, which
will report an error if the CODEC is suspended because it relies on a
volatile register.

To resolve this issue mark CLASS_D_CONTROL_1 as non-volatile and
manually keep the register cache in sync by updating both bits when
changing the mute status.

Mark Brown c969f19f8f ASoC: Compress WM8962 register access map
Reduce the source code size still futher by only specifying non-zero
rows in the WM8962 access map.

Mark Brown f57f6c046f ASoC: Shrink code size for WM8962 register defaults table
Dramatically reduce the code size for the WM8962 register defaults table
by switching to explicitly initialise only defined registers, relying on
static defaulting to zero for the overwelming bulk of the register map.

Similar treatement for the register access table will come later and will
produce a similarly dramatic code size shrink.

Mark Brown 7711308ae6 ASoC: Implement interrupt based jack detection
Allow microphone detection on WM8962 to be performed using the interrupt
signal, allowing the detection of both microphone presence and button
presses with a signal singal from the CODEC to CPU.  Currently a 250ms
debounce time is applied to both short circuit and presence detection,
this has not been optimised.

Mark Brown 9a76f1ff6e ASoC: Add initial WM8962 CODEC driver
The WM8962 is a low power, high performance stereo CODEC designed for
portable digital audio applications.

This initial driver release supports the key audio paths of the WM8962.
Extended functionality, such as microphone detection, digital microphones
and the advanced DSP signal enhancements provided by the device are not
yet supported.
