Your patch contains several coding style issues, most significantly:
Please use tabs for indendation, not spaces. You should run
scripts/checkpatch.pl over your patch next time, it catches most of
the issues.
Otherwise your patch looks fine and I applied it after fixing the coding
style.
Thanks
Sascha

You can do this by adding --in-reply-to <msg-id> to the git send-email
commandline. Anyway, I prefer new versions of patches to be sent as a
new thread, possibly adding a [PATCH v2] prefix. When a thread contains
multiple versions of the same patch it's often hard to find the most
recent patches when it comes to applying them.
Since you are new to open source community, the most important rule is:
Don't give up when people are nagging about small details of your patch.
At least this means people are looking at your stuff ;)

Please answer the question: What describes imx6qdl-udoo.dtsi and
what describes imx6q-udoo.dts ?
I suspect for imx6qdl-udoo.dtsi is a module and imx6q-udoo.dts is a board
uses this module.
Kernel (as an our bootloader) may contain specific code used for the
module and/or for a board. To find out should this code to be executed
or not, some compatibility tests is used.
So, you should add compatible string "AAA" to the module DT description
and strings "BBB", "AAA" to the board.
I hope I have explained clearly. :)
Thanks.

Hum I think I have understand, in fact there is 2 differents type of
UDOO board, one quad and one dual. So I think it is a good idea to add
in imx6qdl-udoo.dtsi a compatible string like "udoo,imx6qdl"
and in the imx6q-udoo.dts a compatible string like "udoo,imx6q" is this right ?
Thanks.
