According to the change history,  seems caused by the patch which
converts txt to dtschema
So should I fix the binding document for this case?

In kernel we also have

arch/arm/boot/dts/actions/owl-s500-roseapplepi.dts:123:                         regulator-name = "AVDD";
arch/arm/mach-s3c/mach-crag6410.c:631:  REGULATOR_SUPPLY("AVDD", "spi0.0"),
arch/arm/mach-s3c/mach-crag6410.c:632:  REGULATOR_SUPPLY("AVDD", "spi0.1"),
arch/arm/mach-s3c/mach-crag6410.c:655:  REGULATOR_SUPPLY("AVDD", "1-001a"),
arch/arm/mach-s3c/mach-crag6410.c:661:  REGULATOR_SUPPLY("AVDD", "1-003a"),

Are those related? Can they affect this one?

Same question. If it's okay to convert, please elaborate that it doesn't have
any side-effects for in-kernel users. Also, check if these names may come from
DTS (some old DTS might have it, in such case it's a documentation issue, or
driver needs to support both).

Thanks.

I go through all the DTS,  no DTS uses DVDD/AVDD or dvdd/avdd for ak4458 and
ak5558 codecs.  so there is no side-effect.

I just am thinking it is better to fix it in document,  it is caused
by converting txt to
dtschema.

You mean no "in-kernel" DTS. But my question was if any DTS in the world may
supply this as AVDD? If answer is yes, the binding must be changed. But then
the same issue may come due to somebody using a new binding somewhere. however
I don't understand how in that case it will work in Linux (only other projects
that use the same bindings as Linux kernel may be affected).

I think this sounds at least like a safer change.

No idea about the roseapplepi one but all the crag6410 ones
are totally different devices from this series.

Generally true, but not always. Do you have an actual problem? The only 
possible problem is you want to use "sound-name-prefix" property. 
Otherwise, you don't need this.

Yes, I want to use "sound-name-prefix" and "#sound-dai-cells".

Then please say that in the commit message. It's not really a fix
unless "sound-name-prefix" was already used.
