      [media] pxa_camera: merge soc_mediabus.c into pxa_camera.c · 34b27b13
      Hans Verkuil 提交于
      Linking soc_mediabus into this driver causes multiple definition linker warnings
      if soc_camera is also enabled:

         drivers/media/platform/soc_camera/soc_mediabus.o:(.text+0x134): first defined here
      
      Since we really don't want to have to use any of the soc-camera code this patch
      copies the relevant code and data structures from soc_mediabus and renames it to pxa_mbus_*.
      
      The large table of formats has been culled a bit, removing formats that are not supported
      by this driver.

      [media] V4L2: platform: Add Renesas R-Car JPEG codec driver · 2c42cdba
      Mikhail Ulyanov 提交于
      Here's the driver for the Renesas R-Car JPEG processing unit.
      
      The driver is implemented within the V4L2 framework as a memory-to-memory
      device.  It presents two video nodes to userspace, one for the encoding part,
      and one for the decoding part.
      
      It was found that the only working mode for encoding is no markers output, so we
      generate markers with software. In the current version of driver we also use
      software JPEG header parsing because with hardware parsing performance is lower
      than desired.
      
      >From a userspace point of view the process is typical (S_FMT, REQBUF,
      optionally QUERYBUF, QBUF, STREAMON, DQBUF) for both the source and destination
      queues. STREAMON can return -EINVAL in case of mismatch of output and capture
      queues format. Also during decoding driver can return buffers if queued
      buffer with JPEG image contains image with inappropriate subsampling (e.g.
      4:2:0 in JPEG and 4:2:2 in capture).  If JPEG image and queue format dimensions
      differ driver will return buffer on QBUF with VB2_BUF_STATE_ERROR flag.
      
      During encoding the available formats are: V4L2_PIX_FMT_NV12M,
      V4L2_PIX_FMT_NV12, V4L2_PIX_FMT_NV16, V4L2_PIX_FMT_NV16M for source and
      V4L2_PIX_FMT_JPEG for destination.
      
      During decoding the available formats are: V4L2_PIX_FMT_JPEG for source and
      V4L2_PIX_FMT_NV12M, V4L2_PIX_FMT_NV16M, V4L2_PIX_FMT_NV12, V4L2_PIX_FMT_NV16
      for destination.
      
      Performance of current version:
      1280x800 NV12 image encoding/decoding
      	decoding ~122 FPS
      	encoding ~191 FPS
