The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
Fix this by calling of_node_put() in error handling too.

The Focusrite Scarlett Gen 2/3 interfaces with internal mixers have a
"standalone" mode. When the interface is not connected to a USB host
and standalone mode is enabled, the interface will pass audio as
previously configured. This patch adds an ALSA control to allow
enabling/disabling that mode.

scarlett2_config_items[] contains the parameters for the configuration
items. The driver previously had two sets of configurations items; one
for devices with no mixer, and one for devices with a mixer. This
patch splits the latter into two (one set for Gen 2 devices and one
set for Gen 3 devices) in preparation for a new item (standalone)
which is present in both but with a different offset.

This adds support for I2S/TDM links where the slot width varies
depending on the sample width, in a way that cannot be guessed by
component hw_params().
A typical example is:
- 16-bit samples use 16-bit slots
- 24-bit samples use 32-bit slots
There is no way for a component hw_params() to deduce from the information
it is passed that 24-bit samples will be in 32-bit slots.
Some audio hardware cannot support a fixed slot width or a slot width
equal to the sample width in all cases. This is usually due either to
limitations of the audio serial port or system clocking restrictions.
Merge series from Stephan Gerhold <stephan@gerhold.net>:
This series adds a simple driver and DT schema for the Awinic AW8738
audio amplifier. It's fairly simple - the main difference to
simple-amplifier is that there is a "one-wire pulse control" that
allows configuring the amplifier to one of a few pre-defined modes.
This can be used to configure the speaker-guard function (primarily
the power limit for the amplifier).
DETECT_MODE and PLL_START must be zero while HP_PDN and ADC_PDN are
both 1. If this condition is broken it can discharge FILT+ and it
can then take up to 1 second for FILT+ to recharge.
There is no workaround required for this, simply avoiding settings
and sequences that would break the requirement. The driver already
meets the requirement.
But it is not obvious from reading the code that this requirement
exists, or what is ensuring it is met. So it would not currently be
obvious to someone changing the code that there is certain special
behaviour that must be maintained.
To avoid accidental breakage in the future:
- Add comments into the register definitions to warn about this so
that anyone changing the code around DETECT_MODE and PLL_START is
aware of this requirement.
- Add a comment where PLL_START is written to 1 to highlight the
requirement and why it is satisfied.
- Add a comment in cs42l42_setup_hs_type_detect() when DETECT_MODE is
initialized.

The parts supported by this driver can have product-specific
firmware and tunings files. Typically these have been used on
embedded systems where the manufacturer is responsible for
installing the correct product-specific firmware files into
/lib/firmware. However, the linux-firmware repository places all
available firmwares into /lib/firmware and it is up to the driver to
select the correct product-specific firmware from that directory.
For example a product containing four smart amplifiers may provide
firmware specific for that product and each of the amplifiers may
have coefficient files containing tunings for their placement in the
mechanical design.
This change extends firmware (wmfw) and coefficient (bin) filenames
to be of the general form:
<cirrus/>part-dspN-fwtype<-system_name<-asoc_component_prefix>>.type
Where the cirrus subdirectory, system_name and asoc_component_prefix
are optional.
New files will be placed in the cirrus subdirectory to avoid
polluting the main /lib/firmware/ location. The generic name must be
searched in /lib/firmware before /lib/firmware/cirrus so that a
generic file in the new location does not override existing
product-specific files in the legacy location.
The search order for firmware files is:
- cirrus/part-dspN-fwtype-system_name-asoc_component_prefix.wmfw
- cirrus/part-dspN-fwtype-system_name.wmfw
- part-dspN-fwtype.wmfw
- cirrus/part-dspN-fwtype.wmfw
- Qualifications are added to the filename so that rightwards is more
specific.
- The system_name is provided by the codec driver.
- The asoc_component_prefix is used to identify tunings for individual
parts because it would already exist to disambiguate the controls
and it makes it obvious which firmware file applies to which device.
The optional coefficient file must have the same filename
construction as the discovered wmfw except:
- where the wmfw has only system_name then the bin file can
optionally include the asoc_component_prefix. This is to allow a
common wmfw for all amps but separate tunings per amp.

2. Manually set to the jack-unplugging state via rt5682s_headset_detect
during going to suspend. Close unnecessary powers and prepare for
re-detecting the CBJ during resuming.

"ret" is normally used as a variable name for return values. In
fsl_sai_set_bclk() it stores the difference between the desired rate and
the rate we can archieve, so rename it to "diff". Also rename "savesub"
to "bestdiff" as that stores the best difference we have found.

The driver tests for the hardware revision being newer than 3.1
with (sai->verid.major >= 3 && sai->verid.minor >= 1). The result
is obviously wrong for hardware revision 4.0. Fix this by storing
the full version in a single variable and comparing to that one.
No practical change at the moment as there is no 4.0 ip version
currently.

Some audio hardware cannot support the same slot width for all sample
widths, or a slot width equal to the sample width for all sample widths.
This is usually due either to limitations of the audio serial port or
system clocking restrictions.
A typical example would be:
- 16-bit samples in 16-bit slots
- 24-bit samples in 32-bit slots
The new dai-tdm-slot-width-map property allows setting a mapping of
sample widths and the corresponding tdm slot widths and slot counts.
Although the slot count is usually the same for all cases this does
allow for adding padding slots to maintain the same bitclk frequency.
The property is added to each endpoint node that needs the component
DAI to be told the TDM slot width and count.

Host is trying to acquire semaphore lock based on HW_SEM_RETRY_COUNT
value which is set to 10 by default. So host will loop for 10 times
trying to acquire lock before giving error msg "Failed to acquire HW
lock". Though this loop count of 10 is good enough with most of the
times but we have observed such failure msg in very few cases(~5 %).
Increase ACP_HW_SEM_RETRY_COUNT to avoid such issue and loop for a
significant time period before throwing error. We're setting newer
loop count to quite higher value of 10K but it's very unlikely that
it will loop for this count, since for most of the cases lock will
get acquired at much lesser loop iterations.

We are using PTE_GRP1 for DMA operations to load firmware binaries
but we are enabling PTE_GRP and flushing ATU cache much before in
probe callbacks. This can cause issue if we try to load firmware
runtime during system resume as probe callback will not be invoked
hence PTE_GRP will not be enabled. Moreover it makes more sense to
flush the cache after register configuration.
Move PTE group register configuration to acp-loader within pre_fw_run
callback to avoid such issue.
