Subject: [PATCH 00/16] Add Allwinner H3/H5/H6/A64 HDMI audio

Hi,

This a merge of serie:
- Add Add H6 I2S support https://patchwork.kernel.org/cover/11497007/
- Add Allwinner H3/H5/A64 HDMI audio https://patchwork.kernel.org/cover/11510511/

I merge both serie because there is a similar issue regarding the I2S polarity.
This need to be investigated under a scope and see if the comment is still true
for Allwinner H6 and previous SoC.
LibreElec team found that we have to introduce the
"simple-audio-card,frame-inversion" property with recent mainline change.
In order to make HDMI audio work.
Maybe the I2S polarity is good or maybe the silicium has an issue but not present
for HDMI I2S or not present in TDM mode...
I cannot do it myself, so if someone want to to do it please feel free.

Regarding the discussion we had here: https://patchwork.kernel.org/patch/11510521/
I didn't switch to generic hdmi card-name and used name like:
sun8i-h3-hdmi, sun50i-h6-hdmi, etc....

Despite this wrong comment the rest of the serie introduce some fix that should
be merged even if it's without the H6 support.

Regards
Clement

Change since v1:
- drop allwinner,playback-channels property
- use coherent hdmi,card-name 
- indentation fix
- collect tags
