1.Since it would be dangerous to specify a newer SoC's compatible
string as the fallback of an older SoC's compatible string, we
add support for the "ingenic,jz4775-spi" compatible string in
the driver.
This will permit to support the JZ4775 by having:
compatible = "ingenic,jz4775-spi";
Instead of doing:
compatible = "ingenic,jz4775-spi", "ingenic,jz4780-spi";
2.Add support for probing the spi-ingenic driver on the X1000 SoC
from Ingenic. From the X1000 SoC onwards, the maximum frequency
allowed by the SSI module of Ingenic SoCs has been changed from
54MHz to 50MHz. So "max_speed_hz" is introduced in "jz_soc_info"
to set different maximum frequency values.
3.Add support for probing the spi-ingenic driver on the X2000 SoC
from Ingenic. The X2000 SoC has only one native chip select line,
so "max_native_cs" is introduced in "jz_soc_info" to set different
maximum number of native chip select lines.
4.Because of the introduction of support for the X-series SoCs, the
current driver is not only applicable to the JZ-series SoCs, so
the description texts has been modified to avoid misunderstanding.

The binding and driver duplicated regulator core feature of controlling
regulators with GPIOs (of_parse_cb + ena_gpiod) and created its own
enable-gpios property with multiple GPIOs.
This is a less preferred way, because enable-gpios should enable only one
element, not multiple. It also duplicates existing solution.
Deprecate the original 'enable-gpios' and add per-regulator property.

Change the order of members in struct cs_dsp_coeff_ctl to avoid
the compiler having to insert alignment padding bytes. On a x86_64
build this saves 16 bytes per control.
- Pointers are collected to the top of the struct (with the exception of
priv, as noted below), so that they are inherently aligned.
- The set and enable bitflags are placed together so they can be merged.
- priv is placed at the end of the struct - it is for use by the
client so it is helpful to make it stand out, and since the compiler
will always pad the struct size to an alignment multiple putting a
pointer last won't introduce any more padding.
- struct cs_dsp_alg_region is placed at the end, right before priv, for
the same reasoning as priv.

As part of the ongoing i2c transition to the simple probe
("probe_new"), this patch uses i2c_match_id to retrieve the
driver_data for the probed device. The id parameter is thus no longer
necessary and the simple probe can be used instead.
In the context of an i2c probe, i2c_match_id with the module id table
and the probed client never returns null, so removing the null check
on the i2c_device_id pointer is safe.
The i2c id tables are moved up before the probe function, as
suggested by Wolfram Sang, except where the existing code already had
a declaration for the of_device_id table.

Once we've set-up the HDA stream and its format, we currently don't
support additional format changes. We already have a protection in the
.prepare case, but this needs to be added in the hw_params too.
In mixing use cases where two DPCM FEs are connected to the same BE,
if can happen that there are multiple calls to the BE hw_params when
the two FEs are configured simultaneously.
This could alternatively be fixed at the DPCM level but that's a more
intrusive change requiring infrastructure changes: this would need to
be paired with the definition of fixed hw_params at the mixer level.

When the system is suspended while a PCM is paused, it doesn't receive
the SUSPEND trigger. So, the SOF driver has to ensure that the PCM and
the widgets associated with the paused PCM are freed in the firmware
during suspend. This is handled in the
sof_tear_down_left_over_pipelines() call. But since the state of this
PCM is SUSPENDED, we end up clearing the prepared flag for the PCM
before freeing it. This results in IPC errors while freeing the widgets.
But because the widget use_counts are reset to 0 even though the IPC
fails, releasing the paused stream after resuming from suspend proceeds
normally.
Fix the IPC errors by removing the clearing of the prepared flag in
sof_set_hw_params_upon_resume(). In fact, we can remove the
sof_set_hw_params_upon_resume() and call
snd_sof_dsp_hw_params_upon_resume() directly. This will ensure that the
PCM is freed in the firmware before the IPC's for freeing the widgets
are sent.

As pointed out by Sascha Hauer, this patch changes:
if (pmc->config && !pcm->config->prepare_slave_config)
<do nothing>
to:
if (pmc->config && !pcm->config->prepare_slave_config)
snd_dmaengine_pcm_prepare_slave_config()
This breaks the drivers that do not need a call to
dmaengine_slave_config(). Drivers that still need to call
snd_dmaengine_pcm_prepare_slave_config(), but have a NULL
pcm->config->prepare_slave_config should use
snd_dmaengine_pcm_prepare_slave_config() as their prepare_slave_config
callback.
Fixes: 9a1e13440a ("ASoC: dmaengine: do not use a NULL prepare_slave_config() callback")
