[PATCH 0/4] Add SOF support for new board revisions

[Daniel Baluta]

We introduce SOF support for new board revisions for i.MX8MP/QM/QXP
which wrt audio they replace wm8960 codec with wm8962.

Also add support for cs42888 codec on i.MX8QM/8QXP baseboard.

Patches 1-3 are already merged in linux SOF tree and they can be merged
via asoc tree.

Patch 4 documents the new compatible strings and can be merged via DT
tree or asoc.

[PATCH 1/4] dt-bindings: arm: imx: Add board revisions for i.MX8MP, i.MX8QM and i.MX8QXP

[Daniel Baluta]

From: Iuliana Prodan <iuliana.prodan@nxp.com>

wm8960 codec is EOL so we have i.MX8MP EVK Rev B4,
i.MX8QM MEK Rev D and i.MX8QXP MEK WCPU boards with
wm8962 codec.
Therefore, add compatibles for them.

[PATCH 2/4] ASoC: SOF: imx: Add mach entry to select cs42888 topology

[Daniel Baluta]

After commit 2b9cdef13648 ("ASoC: SOF: imx: Add devicetree support
to select topologies") we select topology to be used by the board
compatible string in the dts.

Now that we have a way to know when the baseboard is installed, use
the board compatible and select proper topology files when the cs42888
Audio IO card is used.

I am confused. why not use "sof-imx8-cs42888.tplg" in imx8's dts instead
use board's compatible string "fsl,imx8qxp-mek-bb".

More and more boards will be added in future. This file will become bigger
and bigger!

Hi Frank,

So you mean create a dts property named e.g sof-tplg-name and read the
topology name from dts?

dsp {
       firmware-name="sof-imx8.ri";
       tplg-name = "sof-imx8-cs428888.tplg";
};


This was our first approach but then we aligned with the community on
using compatible to match
for properties like default fw path, default tplg path, fw name, tplg name.

Now dts should somehow describe the hardware not the software (e.g
tplg binary) used on that platform.
The growing number of boards will not be a problem, each one will have
a compatible in the dts.

But the concern here is how we describe a hardware setup where we have
a CPU board + a baseboard
like it is the case for cs42888 codec?

Our approach was that in our dts or overlay dts that describes SOF
with cs428888 codec to put the exact
compatible "fsl,imx8qxp-mek-bb" and match it with static vector in SOF
driver that you see in this patch.

SOF core relies on the compatible string in order to identify the
correct tplg_filename for example.

thanks,
Daniel.

  dsp {
	compatible = "imx8-dsp-xxxx";
	...
  }

in dsp driver, map "imx8-dsp-xxxx" to "sof-imx8-cs428888.tplg" and
"sof-imx8.ri".

What's origial email thread. I think "compatible" refer to dsp node, not
to boards level compatible string.

Yes, but your C files will fill up meansless map code when more board
added.

Any application ctrl tools can link these nodes?

[PATCH 3/4] ASoC: SOF: imx8: Add entries for new 8QM and 8QXP revisions

[Daniel Baluta]

From: Iuliana Prodan <iuliana.prodan@nxp.com>

The new revisions for 8QM and 8QXP have wm8962 codec instead of wm8960.
Therefore add new entries in sof_imx8_machs, an array of snd_sof_of_mach,
where we describe topology name and driver name.
For the new revisions we have new compatible values and based on these,
we select the new topology file, for wm8962 codec.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
