From: Laurent Pinchart Date: Sun, 16 Jun 2013 19:01:02 +0000 (+0200) Subject: drm/rcar-du: Introduce CRTCs groups X-Git-Tag: v3.12-rc1~136^2~118^2^2~11 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb2025d2509ffab1c426509fd9de3d83e40398b9;p=pandora-kernel.git drm/rcar-du: Introduce CRTCs groups The R8A7779 DU is split in per-CRTC resources (scan-out engine, blending unit, timings generator, ...) and device-global resources (start/stop control, planes, ...) shared between the two CRTCs. The R8A7790 introduced a third CRTC with its own set of global resources This would be modeled as two separate DU device instances if it wasn't for a handful or resources that are shared between the three CRTCs (mostly related to input and output routing). For this reason the R8A7790 DU must be modeled as a single device with three CRTCs, two sets of "semi-global" resources, and a few device-global resources. Introduce a new rcar_du_group driver-specific object, without any real counterpart in the DU documentation, that models those semi-global resources.
