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.
v3->v4
* Included rzg2-advantech-idk-1110wr-panel.dtsi in
r8a774a1-hihope-rzg2m-ex-idk-1110wr.dts file instead of re-inventing
the wheel.
* Dropped the Ack from Laurent for patch 2/2 due to above changes
v2->v3
* Included Reviewed-by from Rob and Laurent
* Switched to dual license
* Added myself as the maintainer
* Updated copyright year
* Rebased the patches
v1->v2
* fixed a space according to Geert's feedback.
Thanks,
Prabhakar

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 with HiHope RZ/G2M, is the most convenient way to support the
HiHope RZ/G2M when it's connected to the idk-1110wr.
