ASoC: qcom: lpass-cpu: Make I2S SD lines configurable

The LPASS hardware allows configuring the MI2S SD lines to use
when playing/recording audio. However, at the moment the lpass-cpu
driver has SD0 hard-coded for mono/stereo (or additional fixed
SD lines for more channels).

For weird reasons there seems to be hardware that uses one of the
other SD lines for mono/stereo. For example, some Samsung devices
use an external Speaker amplifier connected to Quaternary MI2S.
For some reason, the SD line for audio playback was connected to
SD1 rather than SD0. (I have no idea why...)
At the moment, the lpass-cpu driver cannot be configured to work
for the Speaker on these devices.

The q6afe driver already allows configuring the MI2S SD lines
through the "qcom,sd-lines" device tree property, but this works
only when routing audio through the ADSP.

This commit adds a very similar configuration for the lpass-cpu driver.
It is now possible to add additional subnodes to the lpass device in
the device tree, to configure the SD lines for playback and/or capture.
E.g. for the Samsung devices mentioned above:

&lpass {
dai@3 {
reg = <MI2S_QUATERNARY>;
qcom,playback-sd-lines = <1>;
};
};

qcom,playback/capture-sd-lines takes a list of SD lines (0-3)
in the same format as the q6afe driver. (The difference here is that
q6afe has separate DAIs for playback/capture, while lpass-cpu has one
for both...)

For backwards compatibility with older device trees, the lpass-cpu driver
defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing.
This is equivalent to the previous behavior: Up to 8 channels can be
configured, and SD0/QUAT01 will be chosen when setting up a stream
with fewer channels.

This allows the speaker to work on Samsung MSM8916 devices
that use an external speaker amplifier.

ASoC: SOF: sort out Kconfig, again

The imx8 config keeps causing issues:

WARNING: unmet direct dependencies detected for SND_SOC_SOF_IMX8M
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && IMX_DSP [=n]
  Selected by [m]:
  - SND_SOC_SOF_IMX_OF [=m] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && SND_SOC_SOF_IMX8M_SUPPORT [=y]

This is complicated by two drivers having dependencies on both
platform specific drivers and the SND_SOC_SOF_OF framework code,
and using an somewhat obscure method to build them the same way
as the SOC_SOF_OF symbol (built-in or modular).

My solution now ensures that the two drivers can only be enabled
when the dependencies are met:

- When the platform specific drivers are built-in, everything is
  fine, as SOC_SOF_OF is either =y or =m

- When both are loadable modules, it also works, both for Kconfig
  and at runtime

- When the hardware drivers are loadable modules or disabled, and
  SOC_SOF_OF=y, prevent the IMX_SOF_OF drivers from being turned on,
  as this would be broken.

It seems that this is just an elaborate way to describe two tristate
symbols that have straight dependencies, but maybe I'm missing some
subtle point. It seems to always build for me now.

ASoC: fsl_easrc: mark PM functions __maybe_unused

ifdefs are hard, and in this driver the suspend/resume functions are
the only callers of some other helpers that trigger a harmless warning
when CONFIG_PM is disabled:

      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~

Remove the #ifdef and just mark the callers as __maybe_unused to
suppress the warnings altogether.

The machine driver bdw-rt5650 (for Google buddy) supports 2 or 4-channel
recording while other two drivers support only 2-channel recording. HW
constraints are implemented to reflect the hardware limitation on BDW
platform.

Changes since v1:
- Change the patch title.
- Remove the DUAL_CHANNEL and QUAD_CHANNEL macros which are too obvious.
- Follow the naming convertion, using 'bdw_rt5650_' and 'bdw_rt5677_' to
  name startup functions.
- Refine the comments in startup functions.
- Redesign the bdw_rt5650_fe_startup() function for readability.
- Add an assignment to initialize runtime->hw.channels_max variable.

ASoC: wm8962: set CLOCKING2 as non-volatile register

Previously CLOCKING2 is set as a volatile register, but cause
issue at suspend & resume, that some bits of CLOCKING2 is not
restored at resume, for example SYSCLK_SRC bits, then the output
clock is wrong.

The volatile property is caused by CLASSD_CLK_DIV bits,
which are controlled by the chip itself. But the datasheet
claims these are read only and protected by the security key,
and they are not read by the driver at all.

So it should be safe to change CLOCKING2 to be non-volatile.

Merge series "ASoC: add snd_compress_ops and replace" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

Current snd_soc_component_driver has compr_ops,
but it is created for ALSA, not for ALSA SoC.
This means it doesn't know the callback is for which component,
thus, each callback needs to get component via lookup function.

It is not good design, and will not work in the future,
because ASoC can have multipul same name component which
current lookup function can't handle.

This v2 patch-set adds new snd_compress_ops and call
callbacks with component.
v1 is here

2.17.1

ASoC: Add initial ZL38060 driver

The ZL38060 is a "Connected Home Audio Processor" from Microsemi,
which consists of a Digital Signal Processor (DSP), several Digital
Audio Interfaces (DAIs), analog outputs, and a block of 14 GPIOs.

This driver supports only a tiny subset of the chip's functionality
and possible configurations:
- bypass mode (whole dsp block is bypassed)
- chip's I2S DAI routed directly to/from DACs and microphone
- chip's internal clock is driven by a 12 MHz external crystal
- chip's DAI connected to CPU is I2S, and bit + frame clock master
- chip must be strapped for "host boot": in this mode, firmware will
  be provided by this driver.

ASoC: soc-compress: add snd_compress_ops

Current snd_soc_component_driver has compr_ops, and each driver can
have callback via it. But, it is mainly created for ALSA, thus, it
doesn't have "component" as parameter.
Thus, each callback can't know it is called for which component.
Each callback currently is getting "component" by using
snd_soc_rtdcom_lookup() with driver name.

--- ALSA SoC  ---
...
if (component->driver->compr_ops &&
    component->driver->compr_ops->open)
=> return component->driver->compr_ops->open(stream);
...

--- driver ---
static int xxx_open(struct snd_compr_stream *stream)
{
struct snd_soc_pcm_runtime *rtd = stream->private_data;
=> struct snd_soc_component *component = snd_soc_rtdcom_lookup(..);
...
}

It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple same driver
name component.

To solve this issue, each callback need to be called with component.
We already have many component driver callbacks.
This patch adds new snd_compress_ops, and call it with "component".

--- ALSA SoC  ---
...
if (component->driver->compress_ops->open)
=> return component->driver->compress_ops->open(
component, substream);
~~~~~~~~~
...

--- driver ---
static int xxx_open(struct snd_soc_component *component,
    struct snd_compr_stream *stream)
{
=> /* it don't need to use snd_soc_rtdcom_lookup() */
...
}

EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module
found on i.MX8MN. It is different with old ASRC module.

The primary features for the EASRC are as follows:
- 4 Contexts - groups of channels with an independent time base
- Fully independent and concurrent context control
- Simultaneous processing of up to 32 audio channels
- Programmable filter charachteristics for each context
- 32, 24, 20, and 16-bit fixed point audio sample support
- 32-bit floating point audio sample support
- 8kHz to 384kHz sample rate
- 1/16 to 8x sample rate conversion ratio

ASoC: tegra: Enable audio mclk during tegra_asoc_utils_init()

Tegra PMC clock clk_out_1 is dedicated for audio mclk from Tegra30
through Tegra210 and currently Tegra clock driver keeps the audio mclk
enabled.

With the move of PMC clocks from clock driver into pmc driver, audio
mclk enable from clock driver is removed and this should be taken care
of by the audio driver.

tegra_asoc_utils_init() calls tegra_asoc_utils_set_rate() and audio mclk
rate configuration is not needed during init and the rate is actually
set during the ->hw_params() callback.

So, this patch removes tegra_asoc_utils_set_rate() call and just leaves
the audio mclk enabled.
