If the display pipeline is enabled, the driver will try to enable, and possibly screw up the simple framebuffer U-boot had configured. This series disables the display pipeline by default, and re-enables it for the A31 Hummingbird, which already had its display pipeline enabled. The series can go in after 4.10-rc1, as a fix, but should not be delayed till the next release.
