35f4403edb ASoC: arizona: Use component pin control functions
We need to modify the state of some of our own pins and are currently
not taking account that the pin name may have a name_prefix applied
to it.

Replace the snd_soc_dapm_x_pin functions with the equivalent
snd_soc_component_x_pin functions so that any name_prefix will be
handled automatically.

d3d5c90556 ASoC: arizona: Move notifier functions to header and make inline
These functions are very thin wrappers around core functions, so they
make sense as inline functions.  Also making them inline avoids build
issues in the case where the machine driver is built in but the CODEC
is built as a module.

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.

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.

d81221ff94 ASoC: arizona: Add support for SNDRV_PCM_RATE_KNOT
The Arizona CODECs support several rates that do not have simple defines
in ALSA. This patch adds support for SNDRV_PCM_RATE_KNOT so that users
can open stream at these rates. As part of this we should always set
constraints in arizona_startup, currently we only set the constraints if
we already have a clock to limit rates to that family of sample rates.
This patch updates this to set a constraint of all rates supported by
the chip if we do not already know which family of rates to limit to.
Finally we also reduce the list of rates supported in the constraints to
only include those that are supported on current parts.

26eb5a9a6a ASoC: arizona: Exit startup early if no runtime
commit 9b8ef9f6b3 ("ASoC: dapm: Add startup & shutdown for dai_links")

Added support for calling startup on CODEC to CODEC links, however this
is called with a NULL runtime pointer. There isn't really a sensible way
to pass a valid runtime pointer to a CODEC to CODEC link at the moment,
so we need to make the startup function safe for NULL runtimes.

This patch returns from the Arizona startup function early if there is no
runtime, this is perfectly safe as all the startup function does is set
the PCM constraints for user-space which arn't relevant to a CODEC to
CODEC link anyway.

0e76597128 ASoC: arizona: Poll for FLL clock OK rather than use interrupts
The extcon driver takes the DAPM mutex from within the interrupt thread
in several places, which makes it possible to get into a situation where
the interrupt thread is blocked waiting on the DAPM mutex whilst a DAPM
sequence is running which is attempting to configure the FLL. In this
case the FLL completion can't be completed as as the IRQ handler is
ONE_SHOT, which cause the FLL lock to use the full time out (250mS) and
report that the process timed out.

It is not really practical to make the extcon driver not take the DAPM
mutex from within the interrupt thread, at least not without extensive
modification. So this patch fixes the issue by switching the wait for
the FLL lock to polling. A few fast polls are done first as the FLL
should lock quickly for a good quality reference clock, (indeed it hits
on the first poll on my system) and it will poll every 20mS after that
until it times out.

1cf5a330c0 ASoC: arizona: Fix gain settings of FLL in free-run mode
The wrong register was used to set the gain of ref loop, when changing
the FLL output on an active FLL. This patch corrects the offset of the
gain register.

8019ff6cfc regmap: Use reg_sequence for multi_reg_write / register_patch
Separate the functionality using sequences of register writes from the
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.

This also updates all the clients of multi_reg_write/register_patch.
