[v7,00/16] Add audio support for the MediaTek Genio 350-evk board

  This serie aim to add the following audio support for the Genio 350-evk:
- Playback
  - 2ch Headset Jack (Earphone)
  - 1ch Line-out Jack (Speaker)
  - 8ch HDMI Tx
- Capture
  - 1ch DMIC (On-board Digital Microphone)
  - 1ch AMIC (On-board Analogic Microphone)
  - 1ch Headset Jack (External Analogic Microphone)

Of course, HDMI playback need the MT8365 display patches [1] and a DTS
change documented in "mediatek,mt8365-mt6357.yaml".

Applied patch:
- mfd: mt6397-core: register mt6357 sound codec

Test passed:
- mixer-test log: [3]
- pcm-test log: [4]

Hi guys !

Simple gentle ping, the serie seems ready to be applied.
Thanks

Please don't send content free pings and please allow a reasonable time
for review.  People get busy, go on holiday, attend conferences and so 
on so unless there is some reason for urgency (like critical bug fixes)
please allow at least a couple of weeks for review.  If there have been
review comments then people may be waiting for those to be addressed.

Sending content free pings adds to the mail volume (if they are seen at
all) which is often the problem and since they can't be reviewed
directly if something has gone wrong you'll have to resend the patches
anyway, so sending again is generally a better approach though there are
some other maintainers who like them - if in doubt look at how patches
for the subsystem are normally handled.

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.

Thanks,
Mark

I am seeing several warnings/errors from both GCC and Clang with
ARCH=arm64 allmodconfig after this series appeared in next-20240906.
As far as I can tell, they appear to agree. I wondered how this was not
caught during the series development but perhaps it was written against
a development tree that did not have Arnd's extrawarn series from 6.10
in it yet? I was going to work on a series but I was not sure about the
best way to address the overflow errors, hence just the report.

Are these just warnings introduced by recent versions of the toolchains?
These commits passed an x86 allmodconfig with GCC 12 at each step (I did
catch one warning there with another patch in the series that didn't get
applied) and 0day didn't say anything at any point.

That's relatively modern, though some of the warnings don't look
particularly new and exciting.

That's a bit surprising, regmap_update_bits() takes an unsigned long?  I
suspect the constants need to be defined as unsigned.

Oh, actually right as I was writing that message 0day decided to report
that (and some other things that look rather preexisting), though only
with clang 20.

Not sure, I did not look too hard. At cursory glance, I am not sure x86
allmodconfig would catch these, as this code depends on ARCH_MEDIATEK
(not COMPILE_TEST), which only exists for arm and arm64.

Fair although I still see some of them on old versions too:

Does it? I see it taking 'unsigned int' for all of its parameters.

$ sed -n '1242,1250p' include/linux/regmap.h
int regmap_update_bits_base(struct regmap *map, unsigned int reg,
                            unsigned int mask, unsigned int val,
                            bool *change, bool async, bool force);

static inline int regmap_update_bits(struct regmap *map, unsigned int reg,
                                     unsigned int mask, unsigned int val)
{
        return regmap_update_bits_base(map, reg, mask, val, NULL, false, false);
}

Ah, I hadn't seen that (the other bits were building on x86).

Yeah, like I say some of the warnings didn't look like they were new.

> Does it? I see it taking 'unsigned int' for all of its parameters.

Sorry, I misread the warning there (or was perhaps looking at another
one) and for some reason though it was about dropping signs but it's
rather due to BIT() being defined for longs which is a rather bad
landmine given how common a pattern negation is.  I do see that
synclink.h has some convenient BITn macros for some reason which would
do the trick but really I think it's just a case of open coding the
BIT() usage, or defining a BITI() or something but that seems ugly.
Probably just open code the definitions.
