# This is a BitKeeper generated patch for the following project:
# Project Name: greg k-h's linux 2.4 USB kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
# ChangeSet 1.853 -> 1.854
# drivers/usb/ov511.h 1.8 -> 1.9
# Documentation/usb/ov511.txt 1.5 -> 1.6
# drivers/usb/ov511.c 1.22 -> 1.23
#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/12/20 [EMAIL PROTECTED] 1.854
# Update ov511 to version 1.63. This is a backport of the 2.5 driver,
# which has been in use for months and is known to be stable.
#
# Notable changes:
# * Make use of usb_make_path()
# * Fix an oops when snapshot mode is enabled
# * Get rid of automagic resubmit
# * OV518 is closer to working
# * Clean up OV6x30 register settings
# * Remove some dead code
# --------------------------------------------

+ NAME: ov518_color
+ TYPE: integer (Boolean)
+ DEFAULT: 0 (off)
+ DESC: Enable OV518 color support. This is off by default since it doesn't
+ work most of the time. If you want to try it, you must also load
+ ov518_decomp with the "nouv=0" parameter. If you get improper colors or
+ diagonal lines through the image, restart your video app and try again.
+ Repeat as necessary.

WORKING FEATURES:
o Color streaming/capture at most widths and heights that are multiples of 8.
o RGB24, RGB565, YUV420/YUV420P, YUV422/YUYV, and YUV422P color
