You need an ack from a DT maintainer for this. I have added Rob and
the devicetree list on cc.

Kind regards

I already did comment. It's still wrong as Ulf commented. So fix and
send a new version. It has to go to the DT list if you want to be in
my queue.

After reviewing the history, We guess your mentioned Ulf's comments is as below.
  
"> +- mtk-hs200-cmd-int-delay: HS200 command internal delay setting.
> + The value is an integer from 0 to 31

Please change to:

mediatek,hs200-cmd-delay

... and if there is a unit, like ns or us, please add that a suffix.

> +- mtk-hs400-cmd-int-delay: HS400 command internal delay setting
> + The value is an integer from 0 to 31

mediatek,hs400-cmd-delay and add unit if applicable.

> +- mtk-hs400-cmd-resp-sel: HS400 command response sample selection
> + The value is an integer from 0 to 1

mediatek,hs400-cmd-resp-sel

And make it a boolean value instead!"

==> We already fix this comment in v4. 
We use "mediatek,hs200-cmd-int-delay" to replace "mtk-hs200-cmd-int-delay", 
but not use "mediatek,hs200-cmd-delay". This is because "-int-" here means internal.
We should not drop it.

And this field does not have unit, it only have total 32 stages.
We also change the description in v4.

For comment about "mtk-hs400-cmd-resp-sel", we also make it a boolean value in v4.
And re-name it as "mediatek,hs400-cmd-resp-rising".

Please help to point out where we need to modify.
Thanks.
