e62ebf156f ASoC: rt5645: patch reg-0x8a
reg-8a assign the tracking source for each ASRC tracker. The default
value is 0x0000 which means all ASRC trackers will track LRCK1. But
in most cases, we wish each ASRC tracker track the corresponding LRCK.
i.e. ASRC1 tracks LRCK1, ASRC2 tracks LRCK2 and so on. So, we rewrite
reg-8a as 0x0120.

4c5d146929 ASoC: max98504: Add max98504 speaker amplifier driver
This patch adds driver for the MAX98504 speaker amplifier.  The MAX98504
is a high efficiency mono class D amplifier that features an integrated
boost converter with voltage and current sensing ADCs for Dynamic Speaker
Management.
This driver does not include support for the I2S DAI, as we wouldn't be
able  to test such code in a hardware configuration where the amplifier
has only wired the analogue input.

efc9194bcf ASoC: hdmi-codec: callback function will be called with private data
Current hdmi-codec driver is assuming that it will be registered
from HDMI driver. Because of this assumption, each callback function
has struct device pointer which is parent device (= HDMI).
Then, it can use dev_get_drvdata() to get private data.

OTOH, on some SoC/HDMI case, SoC has VIDEO/SOUND and HDMI IPs.
This case, it needs SoC VIDEO, SoC SOUND and HDMI video, HDMI codec
driver. In DesignWare HDMI IP case, SoC VIDEO (= DRM/KMS) driver tries
to bind DesignWare HDMI video driver, and HDMI codec driver
(= hdmi-codec). This case, above "parent device" of HDMI codec driver
is DRM/KMS driver and its "device" already has private data.

And, from DT and ASoC CPU/Codec/Card binding point of view, HDMI codec
(= hdmi-codec) needs to have "parent device" (= DRM/KMS), otherwise,
it never detect sound card.

Because of these reasons, some driver can't use dev_get_drvdata() to
get private data on hdmi-codec driver. This patch add new void pointer
on hdmi_codec_pdata for private data, and callback function will be
called with it.

5d76de61dd ASoC: adau17x1: Add support for specifying the MCLK using the CCF
The devices from the ADAU17X1 family all have a MCLK clock input which
supplies the master clock for the device. The master clock is used as the
input clock for the PLL. Currently the MCLK rate as well as the desired PLL
output frequency need to be supplied by calling snd_soc_dai_set_pll() form
a machine driver.

Add support for specifying the MCLK using the common clock framework. In
addition to that also automatically configure the PLL to a suitable rate
if the master clock was provided using the CCW. This allows to use the
CODEC driver without any special configuration requirements from the
machine driver.

While the PLL output frequency can be configured over a (more or less)
continuous range the narrowness of the range and the other constraints of
the clocking tree usually only result in two output frequencies that will
actually be chosen. One for 44.1kHz based rates and one for 48kHz based
rates, these are the rates that the automatic PLL configuration will use.
For the rare case where a non-standard setup is required a machine driver
can disable the auto-configuration and configure a custom frequency using
the existing mechanisms.

If the common clock framework is not enabled clk_get() will return NULL and
the driver will function as before and the clock rate needs to be
configured manually.

3d632cc872 ASoC: sgtl5000: Initialize CHIP_ANA_POWER to power-on defaults
Initialize CHIP_ANA_POWER to match power on defaults, which disables
ADC, DAC, and charge pumps.

In the process, remove references to the following register/bitfields
from the sgtl5000_set_power_regs routine:
	CHIP_ANA_POWER/LINREG_SIMPLE_POWERUP and
	CHIP_LINREG_CTRL/LINREG_VDD_MASK

And remove CHIP_ANA_POWER and CHIP_LINREG_CTRL from the set of default
registers so they don't get clobbered by sgtl5000_fill_defaults().

f219b16959 ASoC: sgtl5000: Write all default registers
If an error occurs writing defaults, produce an error message but
continue writing other registers. The failure of a single write should
not cause catastrophic device failure.

In at least one occurrence, I2C writes of CHIP_ANA_POWER were nacked,
though continuing allowed the device to operate properly.

940adb280d ASoC: sgtl5000: Fix regulator support
Regulator support on SGTL5000 is broken because the VDDIO and
VDDA and VDDD should be powered on before enabling MCLK as
shown in Figure 4 of [1]. This requires moving control of the
regulators from the codec block to the I2C block of the driver.

The bulk of this patch consists of swapping the codec device with
the i2c client. The new field num_supplies in struct sgtl5000_priv
is used instead of ARRAY_SIZE(supplies) to handle the special case
when the internal LDO is used instead of external VDDD.

Note that ER1 in the SGTL5000 Errata document [2] suggests that
all designs should use external VDDD.

Since the internal LDO can only be enabled after I2C is available,
there's no benefit in treating it as a regulator, so this patch
removes the regulator structure surrounding it.

Instead, a single block of code in sgtl5000_i2c_probe() performs
the initialization sequence in section 2.2.1.1 of [3] and page
26 of [1].

4983d32526 ASoC: nau8825: mark pm functions __maybe_unused
The newly added nau8825_dai_is_active() function is only called from
the PM logic that is build-time conditional in this driver, so we get
a warning when CONFIG_PM is disabled:

sound/soc/codecs/nau8825.c:229:13: error: 'nau8825_dai_is_active' defined but not used [-Werror=unused-function]
 static bool nau8825_dai_is_active(struct nau8825 *nau8825)

By replacing the #ifdef around the functions with a __maybe_unused
annotation, the code becomes more robust to this kind of problem
and we no longer get the warning while also slightly improving
readability.

8f273aacc0 ASoC: remove one extraneous 'const'
A recent commit made a few arrays 'const', but also added the
same attribute to a function return type, where it makes no
sense, and we get a warning when building with W=1:

sound/soc/codecs/arizona.c:1725:27: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]
 static const char * const arizona_dai_clk_str(int clk_id)

This removes it again.

88b1c01fb4 ASoC: cs53l30: Correct clock inversion check
SND_SOC_DAIFMT_IB_NF = 0x3 (11b) | SND_SOC_DAIFMT_IB_IF = 0x4 (100b)
creates a mask 0x7 (111b) which also includes SND_SOC_DAIFMT_NB_IF
= 0x2 (10b).

So this patch uses the traditional way to check the clock inversion.

a074ae0ed6 ASoC: pcm1681/pcm1791: fix typo in declaration
gcc -Wextra warns about an obvious but harmless typo in the
pcm1681_writeable_reg function, which has an extra 'register
keyword', and in pcm179x, which has a second copy of that
declaration:

sound/soc/codecs/pcm1681.c:76:42: error: 'register' is not at beginning of declaration [-Werror=old-style-declaration]
sound/soc/codecs/pcm179x.c:62:42: error: 'register' is not at beginning of declaration [-Werror=old-style-declaration]

For consistency with the rest of the file, I'm changing this from
'unsigned register' to 'unsigned int', which has the same meaning
but causes no warning.
