RZ/G2N board is pin compatible with RZ/G2M board. However on the SoC
side RZ/G2N uses DU3 where as RZ/G2M uses DU2 for the DPAD. In order to
reuse the common dtsi for both the boards, it is required to move du clock
properties from common dtsi to board specific dts.

This patch adds support for Advantech idk-1110wr LVDS panel.
The HiHope RZ/G2[MN] is advertised as compatible with panel idk-1110wr
from Advantech, however the panel isn't sold alongside the board.

Hi Biju,
Thank you for the patch.

It would be nice if DT had a syntax that allowed extending an existing
property. It would allow us to write
&du {
clocks += <&versaclock5 1>,
<&x302_clk>,
<&versaclock5 2>;
clock-names += "dclkin.0", "dclkin.1", "dclkin.2";
};
in hihope-common.dtsi and be done with it.
Rob, do you think that's something worth adding ?
In any case, until we have that, this patch looks good to me.

Yeah, we already have /delete-property/, but not yet /append-property/.

Should this be named according to the panel name istead of just
"panel-lvds" ? It could be used by any board, and this board could also
use a different LVDS panel.

Could we abbreviate the label name to panel_in ? That way the board .dts
wouldn't need to update the remote-endpoint phandle to use a different
panel, only the #include would need to be changed.

For the same reason I would set the remote-endpoint for &lvds_connector
here. See arch/arm/boot/dts/r8a77xx-aa104xd12-panel.dtsi for an example.

I thought ,we can use a common file for all the LVDS panels used by RZ/G2 boards and refer the panel from board dtsi.
For eg:- RZ/G2[MN] will refer " panel_in_advantech_idk_1110wr" and RZ/G2E will refer " panel_in_advantech_idk_2121wr"
If user wants a different panel, then needs to define panel definitions in this file and use it. But I am not sure it is the right thing to do.
OK. Anyway I will create a panel specific dtsi file and send V2.
