| Subject: drm/exynos: decon5433: Fix per-plane global alpha for XRGB modes |
| |
| From: Marek Szyprowski <m.szyprowski@samsung.com> |
| |
| [ Upstream commit ab337fc274a1957ff0771f19e826c736253f7c39 ] |
| |
| Set per-plane global alpha to maximum value to get proper blending of |
| XRGB and ARGB planes. This fixes the strange order of overlapping planes. |
