Hi Tobias,
2015-04-01 Tobias Jakobi <tjakobi@math.uni-bielefeld.de>:
> While the VP (video processor) supports arbitrary scaling
> of its input, the mixer just supports a simple 2x (line
> doubling) scaling. Expose this functionality and exit
> early when an unsupported scaling configuration is
> encountered.
>
> This was tested with modetest's DRM plane test (from
> the libdrm test suite) on an Odroid-X2 (Exynos4412).
