Hi.

Few comments inline.

Given Fugang Duan is listed as a maintainer I'd also like an ack ideally
from them.  BTW your +CC list seems a bit random.


Thanks,

See the example - doesn't match.  Should be -adc here as well
as this is just part of the SoC.

No objection to having names, but if there is only 1 why is
it required?

Status doesn't need to be here

As the bot pointed out, spaces not tabs for these - Please run the suggested
tests in that email before sending a v2.

No need for a status entry in the example.
