From 79b0c6400517456935f84f8d46c8bb0cf73f1813 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 18 Mar 2013 12:16:34 -0300 Subject: [media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl. This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver.
