[PATCH 0/4] drm/imx: fix TVE / HDMI coexistence

[Dmitry Baryshkov]

Testing MCIMXHDMICARD on IMX53 QSRB platform revealed that the HDMI
output is broken. The TVE output (even unconnected) forces the PLL4
frequency, breaking the frequency selected for the HDMI output. Fix
those issue, making TVE stop grabbing the PLL4 frequency (by correctly
reporting if it is unconnected).

While we are at it, fix two plane-related issues, which are now reported
by DRM.
