 From userspace one can issue DRM_IOCTL_EXYNOS_IPP_GET_LIMITS ioctl,
some examples can be found in Tobias' libdrm git:
https://github.com/tobiasjakobi/libdrm/blob/ippv2/exynos/exynos_ipp.c

In the current version of patches, GSC and FIMC drivers have no limits
defined, because the old v1 IPP drivers didn't have such information.
I will try to add them in v3 of this patchset, I will also include your
recently proposed updates to GSC driver bindings and rotated image size
limit.
