Dear All,
the HiHope RZ/G2M is advertised as supporting panel idk-1110wr from
Advantech, but the panel doesn't come with the board, it has to purchased
separatey, therefore this series adds panel support to a new DT.
v1->v2
* fixed a space according to Geert's feedback.
Thanks,
Fab

Add binding for the idk-1110wr LVDS panel from Advantech.

The HiHope RZ/G2M is advertised as compatible with panel idk-1110wr
from Advantech, however the panel isn't sold alongside the board.
A new dts, adding everything that's required to get the panel to
work the HiHope RZ/G2M, is the most convenient way to support the
HiHope RZ/G2M when it's connected to the idk-1110wr.

I knew that runtime-configurable output routing would be needed one day.
While I'm not opposed to merging this patch as-is, it means that a board
shipping this DT will not support the DSI output. I suppose that's not a
problem as using DSI would require an external DSI panel, which would
require a different DT anyway. In the general case, however,
implementing support in the DU driver for output routing outside the SoC
will be interesting to say the least :-)
