From: Joonyoung Shim Date: Fri, 14 Nov 2014 02:36:02 +0000 (+0900) Subject: drm/exynos: add has_vtsel flag X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c3c9c1d904dca30f89882b97822fdf025b115c9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/exynos: add has_vtsel flag The exynos fimd provides video type selection bits from system register but exynos3 series don't has it, so needs has_vtsel flag and we can distinguish whether set video type selection bits.
