From 86126748cd5063aa888ce252f16b89b35e7d4707 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 18 Oct 2016 17:09:30 +0200 Subject: [PATCH] drm/imx: ipuv3-plane: disable local alpha for planes without alpha channel Without this patch, after enabling the overlay plane with an RGBA framebuffer, switching to a framebuffer without alpha channel would cause the plane to vanish, since the pixel local alpha is constant zero in that case. Disable local alpha again when setting an opaque framebuffer.
