From 01373a5c97ced83d4cb520f7e56c80454a198bfb Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Mon, 30 Jul 2007 12:49:04 -0300 Subject: V4L/DVB (5955): Add support for DiB7070-based devices This changeset adds support for DiB7070P-based devices by adding the dib0070-driver and putting the appropriate layouts into dib0700_devices.c It also includes a new firmware for the dib0700 which is necessary to make the DiB7070-boards work and it also should fix the i2c-problems on some boards.
