Hello everybody, This patch series implement support for rotation in the VSP1 driver. It contains an update of the rotation support part of the "[PATCH 00/13] Renesas R-Car VSP: Scaling and rotation support on Gen3" series. Patch 1/3 starts by fixing the multi-line comment style through the whole driver to avoid adding new offenders in patch 3/3. Patch 2/3 is to biggest addition since v1. It clarifies interactions between formats, controls and buffers in the V4L2 API documentation. The proposal is based on an IRC meeting held on 2016-09-15 in the #v4l channel on freenode which I have tried to translate as accurately as possible into documentation. Patch 3/3 implements rotation support in the vsp1 driver. Beside being rebased on top of the current vsp1/next branch, it has mostly been kept unchanged compared to v1. For your convenience the code is available at git://linuxtv.org/pinchartl/media.git vsp1-rotation-v2-20170228 Laurent Pinchart (3): v4l: vsp1: Fix multi-line comment style v4l: Clearly document interactions between formats, controls and buffers v4l: vsp1: wpf: Implement rotation support Documentation/media/uapi/v4l/buffer.rst | 88 ++++++++++++ drivers/media/platform/vsp1/vsp1_bru.c | 27 ++-- drivers/media/platform/vsp1/vsp1_dl.c | 27 ++-- drivers/media/platform/vsp1/vsp1_drm.c | 21 ++- drivers/media/platform/vsp1/vsp1_drv.c | 12 +- drivers/media/platform/vsp1/vsp1_entity.c | 9 +- drivers/media/platform/vsp1/vsp1_hsit.c | 3 +- drivers/media/platform/vsp1/vsp1_lif.c | 6 +- drivers/media/platform/vsp1/vsp1_pipe.c | 9 +- drivers/media/platform/vsp1/vsp1_rpf.c | 11 +- drivers/media/platform/vsp1/vsp1_rwpf.c | 11 +- drivers/media/platform/vsp1/vsp1_rwpf.h | 3 +- drivers/media/platform/vsp1/vsp1_sru.c | 3 +- drivers/media/platform/vsp1/vsp1_uds.c | 3 +- drivers/media/platform/vsp1/vsp1_video.c | 45 +++++-- drivers/media/platform/vsp1/vsp1_wpf.c | 215 +++++++++++++++++++++++------- 16 files changed, 382 insertions(+), 111 deletions(-) -- Regards, Laurent Pinchart
