eeef16acf8 ASoC: nau8825: change output power for interrupt
The interrupt clock is gated by x1[10:8], one of them needs to be enabled
all the time for interrupts to happen. We change codec to enable ADC
because it's helpful to reduce playback pop noise.
Don't use force enable pin to enable ADC instead of ADC widget event.
That won't interfere DAPM operation and let bias work normally.

3a56103534 ASoC: nau8825: reduce standby power consumption
Decrease internal clock frequency for power saving when standby.
But clock divider needs restore when MCLK as system clock in playback.

407c71b698 ASoC: nau8825: improve FLL function for better performance
In FLL calculation, increase VCO/DCO frequency for better performance.
Besides, have different register configuration according to fraction or not
when apply FLL parameters.

e6cee90075 ASoC: nau8825: Fix jack detection across suspend
Jack plug status is rechecked at resume to handle plug/unplug
in S3 when the chip has no power.

Suspend/resume callbacks are moved from the i2c dev_pm_ops to
snd_soc_codec_driver. soc_resume_deferred is a delayed work
which may trigger nau8825_set_bias_level. The bias change races
against dev_pm_ops, causing jack detection issues.
soc_resume_deferred ensures bias change and snd_soc_codec_driver
suspend/resume are sequenced correctly.

45d5eb3a34 ASoC: nau8825: fix issue that pop noise when start playback
Reduce pop noise in power up and down sequence when playback.
The DAPM widgets graph is reconstructed to ensure the
register write sequence at playback matches exactly to the
v5 clickless sequence provided by Nuvoton.

4454a8378b ASoC: nau8825: add pm function
This patch adds pm function and fixes following issues
1.i2c timeout after resume, after resume we saw interrupt handler
is called prior to i2c controller is resumed.This causes i2c timeout
2.no audio after resume

c86ba612bd ASoC: nau8825: Add FLL configuration
snd_soc_codec_driver.set_pll is implemented to configure the FLL.
The codec internal SYSCLK can be from either the MCLK pin directly,
or the FLL. This is configured by snd_soc_codec_driver.set_pll.
