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 ?

 

Thanks,

angelo
