Can you keep the "samsung,exynos5-gsc" entry with the gsc_v_5250_variant
data, so that it can work with "samsung,exynos5-gsc" compatible in DT
on both exynos5250 and exynos5420 SoCs?
Thank you for your question.
Exynos 5250 and 5420 have different hardware rotation limits.
Exynos 5250 is '.real_rot_en_w/h = 2016' and 5420 is '.real_rot_en_w/h =
2048'.
So my opinion they must have different compatible.
I think there is some misunderstanding, mu suggestion was to keep the
"samsung,exynos5-gsc" compatible entry in addition to the new introduced
ones: "samsung,exynos5250-gsc" and "samsung,exynos5420-gsc". That's in
order to make your changes possibly backward compatible, in theory
the updated driver should still work without changes in dts.
Thank you again for your explanation.
Yes, I understood.
I will keep "samsung,exynos5-gsc" compatible,
and add Exynos 5250/5420/5433 compatible.
Best regards,
Hoegeun
