I'm not clear on what each of the 16 entries represents. What's index 0,
1, 2, etc.?

It's good if the examples include optional properties so we at least
have some validation the schema matches the DTS.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.

Hi Krzysztof,
Thanks for your review first.
I did scripts/get_maintainers.pl based on latest broonie for-next tree,
but I misunderstood the rule about CC list. That's why I only picked
one maintainer for every domain. I will update the CC list in V3.

OK, I will update the file name in V3.

Hi Rob,
Ext Codec -> ETDM_IN -> MEMIF(DMA) -> Memory
The maximum channel number of etdm-in is 16.
The index matches to the input channel ID.
0 : CH0
1 : CH1
...
15: CH15
User can config the channel ID they don't want to be outputted to
memory in the property.
For example,
For 4 channels ETDM connection, and the following property is
configured.
"mediatek,etdm-in1-chn-disabled = <0>;"
Received etdm1 input data outputted to memory will be [d0_ch1, d0_ch2,
d0_ch3, d1_ch1, d1_ch2, d1_ch3, ...]. CH0 is dropped.
