From 3434eb7e14d9587ee56f3462bcfa5726b62dadb9 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 27 Apr 2007 12:31:08 -0300 Subject: V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENT VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl.
