From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx> All modes exposed by simple panels should be tagged as driver defined modes. Moreover, if a panel supports only one mode, this mode is obviously the preferred one. Doing this also fix a problem occurring when a 'video=' parameter is passed on the kernel cmdline. In some cases the user provided mode is preferred over the simple panel ones, which might result in unpredictable behavior.
