Hello all,
Frist, thanks Krzysztof, Robin and Sylwester.
The gscaler has hardware rotation limits. So this patch set support the rotate hardware limits of gsc.
Changes for V4: - Fixed the most specific compatible come first in device tree. - Kept compatible("samsung,exynos5-gsc") in ther driver. - Added mark compatible("samsung,exynos5-gsc") as deprecated. - Added print dmesg if your driver uses compatible("samsung, exynos5-gsc"). - Removed the patch 5, 6 of ver3.
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
