[PATCH 0/3] Add F1C100s audio support

[Csókás, Bence]

Support for Allwinner F1C100s/200s series audio was
merged in the for-next branches of the DMA and ALSA
trees, the last step is to add the codec to DT.
This series was forward-ported/rebased to the best of
my abilities, on top of Linus' tree as of now:
commit feffde684ac2 ("Merge tag 'for-6.13-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux")

There's no real need to resend just the DTS bits, though I appreciate
the effort of making it easier to pick. There should be no difference
due to rebasing, since we didn't have many F1C100s changes.

The DTS bits can only be merged after driver bits have been accepted,
otherwise we would get DT validation errors in -next. After the
notifications yesterday, I started to pick the patches, but it got
late so I hadn't pushed them out yet. Just want you to know that they
haven't been forgotten. :)

BTW, if you merge different patch series and resending, please keep
the highest version number, like you would when resending a single
patch series, and also provide reference links to the originals.
That way we know where it came from and which version it was from.
There have been cases where the latest version was rejected and
an older version was resent.


Thanks
ChenYu
