Subject: [PATCH v3 0/6] Exynos-gsc: Support the hardware rotation limits

Hello all,

The gscaler has hardware rotation limits. So this patch set support
the rotate hardware limits of gsc.

To avoid problems with bisectability, patches 1~4 must be merged and
then merged 5 and 6.

Changes for V3:
- Fixed of_match_node() to of_device_get_match_data() in drm gsc driver.
- Added hardware rotation limits for gsc driver of v4l2.
- Added the remove unnecessary compatible for DT document and Exynos dts.

Changes for V2:
- Added the interface info in binding document.
- Added clean name of compatible in Exynos dts.
- Added maximum supported picture size hardcoded into driver.

Best regards,
Hoegeun
