ASoC: Updates for v5.9
The biggest changes here one again come from Mormioto-san who has
continued his dilligent work cleaning up long standing issues in the
APIs, it's particularly nice to see the transition from digital_mute()
to mute_stream() finally completed. There's also been a lot of work on
the x86 code again, this time a big focus has been on cleaning up some
issues identified by various static tests, and on the Freescale systems.
Otherwise the biggest thing has been a lot of driver additions:
- Convert users of digital_mute() to mute_stream().
- Simplify I/O helper functions.
- Add a helper for getting the RTD from a substream.
- Many, many fixes and cleanups to the x86 code.
- New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
of the first phones I worked on!) and TI J721e EVM.

|

KUnit isn't working, what should I do?
|
||||
======================================
|
||||
|
||||
Unfortunately, there are a number of things which can break, but here are some
|
||||
things to try.
|
||||
|
||||
1. Try running ``./tools/testing/kunit/kunit.py run`` with the ``--raw_output``
|
||||
parameter. This might show details or error messages hidden by the kunit_tool
|
||||
parser.
|
||||
2. Instead of running ``kunit.py run``, try running ``kunit.py config``,
|
||||
``kunit.py build``, and ``kunit.py exec`` independently. This can help track
|
||||
down where an issue is occurring. (If you think the parser is at fault, you
|
||||
can run it manually against stdin or a file with ``kunit.py parse``.)
|
||||
3. Running the UML kernel directly can often reveal issues or error messages
|
||||
kunit_tool ignores. This should be as simple as running ``./vmlinux`` after
|
||||
building the UML kernel (e.g., by using ``kunit.py build``). Note that UML
|
||||
has some unusual requirements (such as the host having a tmpfs filesystem
|
||||
mounted), and has had issues in the past when built statically and the host
|
||||
has KASLR enabled. (On older host kernels, you may need to run ``setarch
|
||||
`uname -m` -R ./vmlinux`` to disable KASLR.)
|
||||
4. Make sure the kernel .config has ``CONFIG_KUNIT=y`` and at least one test
|
||||
(e.g. ``CONFIG_KUNIT_EXAMPLE_TEST=y``). kunit_tool will keep its .config
|
||||
around, so you can see what config was used after running ``kunit.py run``.
|
||||
It also preserves any config changes you might make, so you can
|
||||
enable/disable things with ``make ARCH=um menuconfig`` or similar, and then
|
||||
re-run kunit_tool.
|
||||
5. Try to run ``make ARCH=um defconfig`` before running ``kunit.py run``. This
|
||||
may help clean up any residual config items which could be causing problems.
|
||||
6. Finally, try running KUnit outside UML. KUnit and KUnit tests can run be
|
||||
built into any kernel, or can be built as a module and loaded at runtime.
|
||||
Doing so should allow you to determine if UML is causing the issue you're
|
||||
seeing. When tests are built-in, they will execute when the kernel boots, and
|
||||
modules will automatically execute associated tests when loaded. Test results
|
||||
can be collected from ``/sys/kernel/debug/kunit/<test suite>/results``, and
|
||||
can be parsed with ``kunit.py parse``. For more details, see "KUnit on
|
||||
non-UML architectures" in :doc:`usage`.
|
||||
|
||||
If none of the above tricks help, you are always welcome to email any issues to
|
||||
kunit-dev@googlegroups.com.

Everest ES8316 audio CODEC
|
||||
|
||||
This device supports both I2C and SPI.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : should be "everest,es8316"
|
||||
- reg : the I2C address of the device for I2C
|
||||
|
||||
Optional properties:
|
||||
|
||||
- clocks : a list of phandle, should contain entries for clock-names
|
||||
- clock-names : should include as follows:
|
||||
"mclk" : master clock (MCLK) of the device
|
||||
|
||||
Example:
|
||||
|
||||
es8316: codec@11 {

The audio support on the board is using pcm3168a codec connected to McASP10
|
||||
serializers in parallel setup.
|
||||
The pcm3168a SCKI clock is sourced from j721e AUDIO_REFCLK2 pin.
|
||||
In order to support 48KHz and 44.1KHz family of sampling rates the parent
|
||||
clock for AUDIO_REFCLK2 needs to be changed between PLL4 (for 48KHz) and
|
||||
PLL15 (for 44.1KHz). The same PLLs are used for McASP10's AUXCLK clock via
|
||||
different HSDIVIDER.
|
||||
|
||||
Clocking setup for 48KHz family:
|
||||
PLL4 ---> PLL4_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk

The Infotainment board plugs into the Common Processor Board, the support of the
|
||||
extension board is extending the CPB audio support, decribed in:
|
||||
sound/ti,j721e-cpb-audio.txt
|
||||
|
||||
The audio support on the Infotainment Expansion Board consists of McASP0
|
||||
connected to two pcm3168a codecs with dedicated set of serializers to each.
|
||||
The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin.
|
||||
|
||||
In order to support 48KHz and 44.1KHz family of sampling rates the parent clock
|
||||
for AUDIO_REFCLK0 needs to be changed between PLL4 (for 48KHz) and PLL15 (for
|
||||
44.1KHz). The same PLLs are used for McASP0's AUXCLK clock via different
|
||||
HSDIVIDER.
|
||||
|
||||
Note: the same PLL4 and PLL15 is used by the audio support on the CPB!
|
||||
|
||||
Clocking setup for 48KHz family:
|

Socionext UniPhier SoC audio driver
|
||||
|
||||
The Socionext UniPhier audio subsystem consists of I2S and S/PDIF blocks in
|
||||
the same register space.
|
||||
|
||||
Required properties:
|
||||
- compatible : should be one of the following:
|
||||
"socionext,uniphier-ld11-aio"
|
||||
"socionext,uniphier-ld20-aio"
|
||||
"socionext,uniphier-pxs2-aio"
|
||||
- reg : offset and length of the register set for the device.
|
||||
- interrupts : should contain I2S or S/PDIF interrupt.
|
||||
- pinctrl-names : should be "default".
|
||||
- pinctrl-0 : defined I2S signal pins for an external codec chip.
|
||||
- clock-names : should include following entries:
|
||||
"aio"
|
||||
- clocks : a list of phandle, should contain an entry for each
|
||||
entry in clock-names.

|
||||
|
||||
Optional properties:
|
||||
- socionext,syscon: a phandle, should contain soc-glue.

The soc-glue is used for changing mode of S/PDIF signal pin
|
||||
to Output from Hi-Z. This property is optional if you use
|
||||
I2S signal pins only.
