Subject: Re: [PATCH v1 1/2] ARM: dts: add rockchip PX3 Evaluation board
Hi Andy,
This patch didn't make it to linux-rockchip list somehow...
Not sure why I'm CC'ed, I don't have access to such a board to check, so
just a couple formal nitpicks:

"integrated"
but the grammar is somewhat incorrect with "which" referring to field -
I assume you meant "with integrated CVBS..."?

Also please always leave a space before an opening parenthesis in
English text. Similarly above, spaces around "/" would help recognize
that MIPI DSI belongs together rather than being two lists.
If nothing else applies below then maybe Heiko can edit it for you?

How compatible is PX3 with RK3188? It is a separate SoC product:
http://www.rock-chips.com/a/en/products/rkpower/2015/1125/730.html
Wondering whether or not to drop the third compatible string.

I'm surprised there is no [rk3188-]px3.dtsi here! Surely some automotive
vendor may design their own board with it and should have at least the
two trailing compatible strings pre-set.

Generally it is undesired to repeat the compatible name as node name -
did you compare other .dts files? (e.g., accelerometer@18 would be
self-documenting) If this is a copy from an existing .dts then please
ignore this comment.

Otherwise formally looks fine.
