Just started testing with v3.12-rc3 +
e6e7fb1ffc875adf2dd36d4a135b8d7addda0aea (top of torvalds tree.)

This needs to be:
#include "ipu-v3/imx-ipu-v3.h"

Otherwise.

drivers/staging/imx-drm/imx-hdmi.c:27:28: fatal error:
drm/imx-ipu-v3.h: No such file or directory
 #include <drm/imx-ipu-v3.h>
                            ^
compilation terminated.
