------------------------
@ Use correct image size in urb_complete()


1:1.23 (15 January 2005)
------------------------
@ Allocate the correct number of buffer memory bytes for read()
* Wakeup interruptible events on DEV_MISCONFIGURED status
* Allocate the exact number of buffers (nreadbuffers) in poll() 
* Documentation updates


1:1.22 (8 January 2005)
-----------------------
= sync with kernel changes


1:1.21 (7 December 2004)
------------------------
@ Fix the sysfs interface
@ Fix allocated minor number after device detection
+ Add "force_munmap" module parameter
+ Documentation updates
+ Add support for old VIDIOC_S_PARM_OLD and VIDIOC_S_CTRL_OLD ioctl's


1:1.20 (8 November 2004)
------------------------
* SN9C10x system clock fine-tuning when switching from native to compressed
  format and viceversa for each image sensor
+ Add sn9c102_i2c_try_raw_read()
+ Frame header available from sysfs interface
+ Documentation updates: new "Video frame formats" paragraph, new entries in
  "Credits" and frame header description
+ Support for HV7131D and MI-0343 image sensors


1:1.19 (4 November 2004) - in Linux kernel only
-----------------------------------------------
- Remove SN9C10x pixelformat definition, since it is now included in the kernel
- Remove "DAC sign" controls for PAS106B and PAS202BCB image sensors
* Use V4L2_CTRL_TYPE_BOOLEAN type for "DAC sign" of PAS106B and PAS202BCB
  sensor controls
* Documentation updates
* Replace wait_event_interruptible() with wait_event_timeout()
* Use msecs_to_jiffies() for timeouts in jiffies


1:1.17 (2 November 2004)
------------------------
@ Fix VIDIOC_ENUM_FMT ioctl
@ Get ride of next SOF header at the end of a compressed frame
@ read() returns buf.bytesused instead of buf.length on success
* Use usb_make_path() on VIDIOC_QUERYCAP for device path in the usb tree


1:1.16 (22 October 2004)
------------------------
@ Add VM_IO flag to vma before memory mapping
@ Fix VIDIOC_TRY_FMT ioctl
= Memory management updates
= module_param_array() updates
* Documentation updates
+ Add DAC magnitude, DAC sign, green balance and exposure controls for PAS106B
  and PAS202BCB image sensors
+ Add an additional pixel format for compressed video: V4L2_PIX_FMT_SN9C10X
+ VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP are used to set or get the current
  compression quality
+ New documentation note in "Notes for V4L2 application developers" paragraph
  about video formats and compressed data.
+ Add documentation on how to define the initial pixel format and compression
  quality in "sn9c102_sensor.h" (see the comments under the "pix_format"
  structure)


1:1.15 (21 October 2004)
------------------------
@ Fix a compilation problem due to recent changes in kernel API not being
  included in stable versions yet


1:1.14 (16 October 2004)
------------------------
@ Fix SOF/EOF problems with TAS5130D1B image sensor
+ Add informations about supported image sensor control settings (shown when
  the module is loaded with 'debug=3' option)


1:1.13 (15 September 2004)
--------------------------
* Documentation updates
+ Implement VIDIOC_G_PARM and VIDIOC_S_PARM ioctl's
- Remove brightness control from PAS106B and PAS202BCB, since it has no effect
  on the active pixel area (it's just for window border lines)
= Memory management updates


1:1.12 (5 September 2004)
-------------------------
* Color fixes for PAS202BCB - from its maintainer -


1:1.11 (30 August 2004)
