Hi Geert and others,
I have successfully applied the patch and build R-car M2 Kernel for Koelsch Board..now it support LVDS..Thank you all especially Geert and Laurent..now i tried the same source tree(v4.7.5) to build for R-Car E2(ALT)Board to make LVDS up..but i am getting the following error during making .dtb file
ubuntu@teltvm2468l:~/jithin_new/linux-4.7.5$ make -j4 r8a7794-alt.dtb
DTC arch/arm/boot/dts/r8a7794-alt.dtb
Error: arch/arm/boot/dts/r8a77xx-aa104xd12-panel.dtsi:39.1-16 Label or path lvds_connector not found

make: *** [r8a7794-alt.dtb] Error 2
ubuntu@teltvm2468l:~/jithin_new/linux-4.7.5$
I have included the "#include "r8a77xx-aa104xd12-panel.dtsi" in r8a7794-alt.dts
my source tree is v4.7.5 stable edition

No one has added LVDS support for r8a7794/alt yet.

The R8A7794 has no LVDS output. The Alt board uses an RGB to LVDS bridge,
similar to the one used by the Marzen board. You can have a look at the Marzen
DT to see how to implement that.
