Analysis of - the tuner driver showed clearly three things. - - 1. The tuner driver didn't support the LinuxTV tuner API - so the code Realtek added had to be removed. - - 2. A significant amount of the driver is reference driver code - from MaxLinear, I felt it was important to identify and - preserve this. - - 3. New code has to be added to interface correctly with the - LinuxTV API, as a regular kernel module. - - Other than the reference driver enum's, I've clearly marked - sections of the code and retained the copyright of the - respective owners. -*/ + * For the Realtek RTL chip RTL2831U + * Realtek Release Date: 2008-03-14, ver 080314 + * Realtek version RTL2831 Linux driver version 080314 + * ver 080314 + * + * for linux kernel version 2.6.21.4 - 2.6.22-14 + * support MXL5005s and MT2060 tuners (support tuner auto-detecting) + * support two IR types -- RC5 and NEC + * + * Known boards with Realtek RTL chip RTL2821U + * Freecom USB stick 14aa:0160 (version 4) + * Conceptronic CTVDIGRCU + * + * Copyright (c) 2008 Realtek + * Copyright (c) 2008 Jan Hoogenraad, Barnaby Shearer, Andy Hasper + * This code is placed under the terms of the GNU General Public License + * + * Released by Realtek under GPLv2. + * Thanks to Realtek for a lot of support we received ! + * + * Revision: 080314 - original version + */ +#include <linux/kernel.h> +#include <linux/init.h> +#include <linux/module.h> +#include <linux/string.h> +#include <linux/slab.h> +#include <linux/delay.h> +#include "dvb_frontend.h" #include "mxl5005s.h" -static int debug = 2;
