From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> To: dri-devel@lists.freedesktop.org Cc: linux-sh@vger.kernel.org Subject: [PATCH 07/12] drm: rcar-du: Replace drm_encoder with drm_slave_encoder Date: Wed, 24 Sep 2014 20:04:27 +0000 [thread overview] Message-ID: <1411589072-28609-8-git-send-email-laurent.pinchart+renesas@ideasonboard.com> (raw) In-Reply-To: <1411589072-28609-1-git-send-email-laurent.pinchart+renesas@ideasonboard.com> DRM slave encoders require their associated struct drm_encoder instance to be embedded in a struct drm_slave_encoder. This makes processing encoders regardless of their types needlessly and painfully complex in drivers that use a mix of slave encoders and custom encoders. Such a driver will need to either create drm_slave_encoder instances that fake their embedded encoder instance, or to turn all drm_encoder instances into drm_slave_encoder instances. Between the two evils, one must choose the lesser. Use drm_slave_encoder everywhere.
