Subject: [PATCH v2 00/11] Rockchip ISP1 Driver
Date:   Fri, 24 Nov 2017 10:36:55 +0800
Message-Id: <20171124023706.5702-1-jacob-chen@iotwrt.com>

Precedence: bulk

This patch series add a ISP(Camera) v4l2 driver for rockchip rk3288/rk3399 SoC.

Kernel Branch:
https://github.com/wzyy2/linux/tree/rkisp1/drivers/media/platform/rockchip/isp1

Below are some infomations about driver/hardware:

Rockchip ISP1 have many Hardware Blocks(simplied):

  MIPI      --> ISP --> DCrop(Mainpath) --> RSZ(Mainpath) --> DMA(Mainpath)
  DMA-Input -->     --> DCrop(Selfpath) --> RSZ(Selfpath) --> DMA(Selfpath);)

(Acutally the TRM(rk3288, isp) could be found online...... which contains a more detailed block diagrams ;-P)

The funcitons of each hardware block:

  Mainpath : up to 4k resolution, support raw/yuv format
  Selfpath : up tp 1080p, support rotate, support rgb/yuv format
  RSZ: scaling 
  DCrop: crop
  ISP: 3A, Color processing, Crop
  MIPI: MIPI Camera interface

Media pipelines:

  Mainpath, Selfpath <-- ISP subdev <-- MIPI  <-- Sensor
  3A stats           <--            <-- 3A parms

Code struct:

  capture.c : Mainpath, Selfpath, RSZ, DCROP : capture device.
  rkisp1.c : ISP : v4l2 sub-device.
  isp_params.c : 3A parms : output device.
  isp_stats.c : 3A stats : capture device.
  mipi_dphy_sy.c : MIPI : sperated v4l2 sub-device.

Usage:
  ChromiumOS:
    use below v4l2-ctl command to capture frames.

      v4l2-ctl --verbose -d /dev/video4 --stream-mmap=2
      --stream-to=/tmp/stream.out --stream-count=60 --stream-poll

    use below command to playback the video on your PC.

      mplayer /tmp/stream.out -loop 0 --demuxer=rawvideo
      --rawvideo=w=800:h=600:size=$((800*600*2)):format=yuy2
    or
      mplayer ./stream.out -loop 0 -demuxer rawvideo -rawvideo
      w=800:h=600:size=$((800*600*2)):format=yuy2

  Linux:
    use rkcamsrc gstreamer plugin(just a modified v4l2src) to preview.

      gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 disable-3A=true
      videoconvert ! video/x-raw,format=NV12,width=640,height=480 ! kmssink
