[PATCH v2 0/4] R-Car VSP1 1-D Histogram support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This patch series implements support for the Renesas R-Car VSP1 1-D histogram
generator (HGO). It is based on top of the latest media tree's master branch,
and available for convenience at

        git://linuxtv.org/pinchartl/media.git vsp1/hgo

The series starts with the implementation and documentation of the new V4L2
metadata API (1/4), followed by a new pixel format for the R-Car VSP1 1-D
histogram (2/4). The last two patches (3/4 and 4/4) implement support for the
API in the vsp1 driver.

Laurent Pinchart (4):
  v4l: Add metadata buffer type and format
  v4l: Define a pixel format for the R-Car VSP1 1-D histogram engine
  v4l: vsp1: Add HGO support
  v4l: vsp1: Don't create HGO entity when the userspace API is disabled
