[PATCH] v4l: vsp1: Disable HSV formats on Gen3 hardware

While all VSP instances can process HSV internally, on Gen3 hardware reading or writing HSV24 or HSV32 from/to memory causes the device to hang. Disable those pixel formats on Gen3 hardware. Signed-off-by: Laurent Pinchart ---

[PATCH v3 0/8] R-Car VSP1 Histogram Support

Hello, This patch series implements support for the Renesas R-Car VSP1 1-D and 2-D histogram generators (HGO and HGT). It is based on top of the VSP1 rotation patches and available for convenience at git://linuxtv.org/pinchartl/media.git vsp1-histogram-v3-20170228 The series starts

[PATCH v3 5/8] v4l: Define a pixel format for the R-Car VSP1 1-D histogram engine

The format is used on the R-Car VSP1 video queues that carry 1-D histogram statistics data. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus --- Documentation/media/uapi/v4l/meta-formats.rst | 15 ++

[PATCH v3 7/8] v4l: Define a pixel format for the R-Car VSP1 2-D histogram engine

From: Niklas Söderlund The format is used on the R-Car VSP1 video queues that carry 2-D histogram statistics data. Signed-off-by: Niklas Söderlund Reviewed-by: Laurent Pinchart

[PATCH v3 6/8] v4l: vsp1: Add HGO support

The HGO is a Histogram Generator One-Dimension. It computes per-channel histograms over a configurable region of the image with optional subsampling. Signed-off-by: Laurent Pinchart --- drivers/media/platform/vsp1/Makefile | 2 +-

[PATCH v3 3/8] v4l: vsp1: Support histogram generators in pipeline configuration

Histogram generators are single-pad entities that branch as leaf nodes at any point in the pipeline. Make sure that pipeline traversal and routing configuration support them correctly. Support for the actual HGO and HGT operation will come later. Signed-off-by: Laurent Pinchart

[PATCH v3 2/8] v4l: vsp1: Add histogram support

The histogram common code will be used to implement support for both the HGO and HGT histogram computation engines. Signed-off-by: Laurent Pinchart --- drivers/media/platform/Kconfig | 1 + drivers/media/platform/vsp1/Makefile | 1 +

[PATCH v2 2/3] v4l: Clearly document interactions between formats, controls and buffers

V4L2 exposes parameters that influence buffers sizes through the format ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT and VIDIO_S_FMT). Other parameters not part of the format structure may also influence buffer sizes or buffer layout in general. One existing such parameter is rotation, which is
