#1728618 — [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

#1728621 — [PATCH v3 1/6] [media] exynos-gsc: Add compatible for Exynos 5250 and 5420 specific version

Exynos 5250 and 5420 have different hardware rotation limits.
Since we have to distinguish between these two, we add different
compatible(samsung,exynos5250-gsc and samsung,exynos5420-gsc).
