Hello, This patch series implements support for the R-Car H3 ES2.0 SoC in the VSP and DU drivers. Compared to the H3 ES1.1, the H3 ES2.0 has a new VSP2-DL instance that includes two blending units, a BRU and a BRS. The BRS is similar to the BRU but has two inputs only, and is used to service a second DU channel from the same VSP through a second LIF instances connected to WPF.1. The patch series starts with a small fixes and cleanups in patches 01/14 to 05/14. Patch 06/14 prepares the VSP driver for multiple DU channels support by extending the DU-VSP API with an additional argument. Patches 07/14 to 10/14 gradually build H3 ES2.0 support on top of that by implementing all needed features in the VSP driver. So far the VSP driver always used headerless display lists when operating in connection with the DU. This mode of operation is only available on WPF.0, so support for regular display lists with headers when operating with the DU is added in patch 11/14. The remaining patches finally implement H3 ES2.0 support in the DU driver, with support for VSP sharing implemented in patch 12/14, for H3 ES2.0 PLL in patch 13/14 (by restricting the ES1.x workaround to ES1.x SoCs) and for RGB output routing in patch 14/14. Compared to v1, the series has gone under considerable changes. Testing locally on H3 ES2.0 uncovered multiple issues in the previous partially tested version, which have been fixed in additional patches. The following changes can be noted in particular. - New small cleanups in patches 02/14 to 05/14 - Pass the pipe index to vsp1_du_atomic_update() explicitly - Rebase on top of the VSP-DU flicker fixes, resulting in a major rework of "v4l: vsp1: Add support for header display lists in continuous mode" - New patches 09/14, 10/14 and 12/14 to support the previously untested VGA output The series is based on top of Dave's latest drm-next branch as it depends on patches merged by Dave for v4.13. It depends, for testing, on - the sh-pfc-for-v4.13 branch from Geert's renesas-drivers tree - the "[PATCH v2 0/2] R-Car H3 ES2.0 Salvator-X: Enable DU support in DT" patch series For convenience, a branch merging this series with all dependencies is available from git://linuxtv.org/pinchartl/media.git drm/next/h3-es2/merged with the DT and driver series split in two branches respectively tagged drm-h3-es2-dt-20170626 and drm-h3-es2-vsp-du-20170626. The patches have been tested on the Lager, Salvator-X H3 ES1.x, Salvator-X M3-W and Salvator-XS boards. All outputs have been tested using modetest without any noticeable regression.
