[RFC PATCH] ARM: dts: imx6: add new board RIoTboard

Tue May 6 15:03:32 PDT 2014
add element14s RIoTboard http://www.riotboard.org which is an i.MX6Solo
based design targeted at makers.
Where upstream drivers exist I've enabled them, the only exception being i2c3
which has been sacrificed for the fec interrupt workaround. i2c3 is only
currently being used for element14s LCD8000-97C lvds connected touch screen,
but as no upstream driver exists for the touch controller I deem this to be
an acceptable compromise for now.
I've also left out enabling ldb due to current problems to coexist with hdmi
although I have tested that it can work on the board with hdmi disabled.
The fec interrupt errata seems to suggest that a different gpio could be used
but I can't find any documentation or example dts that does so. Suggestions
welcome.
