58c0213872 ASoC: max98095: Fix enum ctl accesses in a wrong type
"Biquad1 Mode" and "Biquad2 Mode" ctls in max98095 codec driver are
enum, while the current driver accesses wrongly via
value.integer.value[].  They have to be via value.enumerated.item[]
instead.

2595b7fe1a ASoC: arizona: Make logging of FLL calculations clearer
The debug logging of FLL calculations was confusing. Values were
printed in hex without indicating this by a leading 0x, and
despite these normally being required in decimal. Also where the
register value isn't the actual value (it s a power-of-two or
0 means 1, 1 means 2, ...)  it was unclear whether the actual or
register value was shown.

This patch changes the log print so that all mathematical values
are shown in decimal, all register values are shown in hex with a
0x prefix, and where the register value isn't the actual integer
value the decimal integer value is shown in () after the hex
register value.

Cvt and pin for a dai are now derived from the already stored pcm
list of device opened.  We query connection list of a pin from
codec to validate the cvt<->pin map.

If connection list returns zero, then monitor is not connected so

4a3478debf ASoC: hdac_hdmi: Add jack reporting
Jack is created based on pcm devices enumerated, so we will
create Jack as "HDMI/DP, pcm=x Jack". This style is expected by
current usermode like PulseAudio and CRAS.

This patch exports an API which can be used to register Jack
based on PCM. This API also establishes the map between PCM and
cvt. Further cvt to pin mapping is established with the help of
usermode selection based on the board topology.

During device probe as the PCMs may not be registered, initial
pin sense don't report jack events. So, first time jack reporting
is done during user selection of mux control.

79f4e922b5 ASoC: hdac_hdmi: Create widget/route based on nodes enumerated
In skylake, HDMI codec enumerates 3 pins and 3 cvts. Stream can
be routed from any cvt to any pin based on the connection list
queried from the pin.

This patch removes the static modelling of widget/route and
creates it dynamically based on the codec widgets enumerated.

Mux widgets are added to represent the map between a cvt and pin.
Ideally the mux widgets should be created based on the connection
list queried from the pin widget. But due to HW behavior, if an
external display is not connected on a port, querying the
connection list returns zero. So create mux widgets to map all
the cvt to all pins. At runtime, playback support on a pin can be
verified based on the connection list query.

Few function in driver have additional arguments now to support
this.

01582a8414 ASoC: arizona: fref must be limited in pseudo-fractional mode
When the FLL is in pseudo-fractional mode there is an additional
limit on fref based on the fratio, to prevent aliasing around the
Nyquist frequency. If fref exceeds this limit the refclk divider
must be increased and the calculation tried again until a suitable
combination of fref and fratio is found or we have to fall back to
integer mode.

This patch also adds some debug log prints around this code.
