kernel 3.14, select display timings from command line

Dear all,


i have a imx6q board similar to sabreauto.


Generally i use a display type1 on LVDS0 and a display type2 on LVDS1.


But sometime i need to swap them.


In previous kernel version as 3.10.17, this was possible simply changing the kernel mxcfb resolutions in kernel cmdline params.

In kernel 3.14, a new devictree node has been added, and display timing and resolution need to be specified there.


But, when i switch the 2 displays i have now to change the device tree.


Is there any way to avoid this kernel / dts re-build ?
