From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dmitry Osipenko Subject: [PATCH v2] drm/tegra: plane: Keep 'dependent' blending state of unaffected planes Date: Thu, 15 Mar 2018 17:24:31 +0300 Message-ID: Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Thierry Reding Cc: dri-devel@lists.freedesktop.org, linux-tegra@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-tegra@vger.kernel.org This way new state takes into account the current state of unaffected (by the atomic commit) planes.
