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.

Since ASoC does not yet really have the framework features needed to
support propagating sample rates through the device well yet implement
basic support for the ISRCs equivalent to that we currently have for the
ASRCs. The user can opt for 8kHz or 16kHz as the rate for the DSP blocks
in addition to the main audio rate, these being the primary use cases.

Some system designs have been identified which repurpose portions of the
speaker driver circuits for other functions which will require that they
not be managed using DAPM. Prepare for this by factoring out the creation
of the speaker widgets into the core driver, the widgets will be replaced
by dummy ones when the additional functions are enabled.

Since we are automatically managing the mutes we may as well also manage
the volume update bits, disabling volume updates while none of the inputs
are active. Since we are doing this we may as well allow the volumes to
ramp together so only enable volume updates once at the end of power up.

This patch allows the REFCLK to be set directly allowing much greater
flexibility in how the FLLs are configured.

Previously updates that only changes FLL source would be missed, this
patch corrects this. We also ensures that both REFCLK and SYNCCLK
frequency changes are considered, in preparation for future updates.

This patch caches the current SYNCCLK settings in the arizona_fll struct
and uses these to simplify the code which determines which source should
be used for the REFCLK and SYNCCLK inputs.

initialisation function.

We only log the result and since the interrupt triggers on loss of lock
during shutdown this may lead to spurious interrupts during shutdown
delaying the process.

Some systems use external analogue switches to connect more analogue
devices to the CODEC than are supported by the device. In some systems
this requires changing the switched output from single ended to
differential mode dynamically at runtime. Add a new function
arizona_set_output_mode() to support this.

The FLL source constants were numbered as a simple enumeration but were
being used in the code as direct values to be written to the registers.
Renumber the constants to reflect the usage.

The Asynchronous Sample Rate Converters on the wm5102/wm5110 have no
mixer attached to their input, but they do allow the input to be
selected from a number of sources via a multiplexer. Currently the
platform assumes the presence of 4 multiplexers and a mixer for each
block.
This patch adds support multiplexed single input blocks into the Arizona
platform.

The Wolfson Arizona series of audio hub CODECs can share a large amount

adds some of this core support, providing a basis for the initial WM5102
audio driver.
