From mboxrd@z Thu Jan 1 00:00:00 1970 From: maxime.ripard@bootlin.com (Maxime Ripard) Date: Tue, 13 Mar 2018 21:54:22 +0100 Subject: [PATCH v4 2/5] drm/atmel-hclcdc: Convert to the new generic alpha property In-Reply-To: References: Message-ID: <55b1ccab40f9ed5ba8fd72467f5bf6ef6b13eed0.1520974361.git-series.maxime.ripard@bootlin.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Now that we have support for per-plane alpha in the core, let's use it.
