From 391cd727eac2e10be7685efd739a3ea9de87393c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 23 Jun 2005 22:02:43 -0700 Subject: [PATCH] tuner-core.c improvments and Ymec Tvision TVF8533MF support tuner-core.c, tuner.h: - tuner-core changed to support multiple I2C devices used on some adapters; - Kconfig now has an option (CONFIG_TUNER_MULTI_I2C) to enable this new behavor; - By default, even enabling CONFIG_TUNER_MULTI_I2C, tuner-core emulates the old behavor, using first I2C device for both FM and TV; - There is a new i2c command (TUNER_SET_ADDR) to allow tuner clients to select I2C address for FM or TV tuner; - Tuner I2C dettach now generates a warning on syslog if failed. tuner-simple.c: - TVision TVF-8531MF and TVF-5533 MF tuner included. It uses, by default, I2C on 0xC2 address for TV and on 0xC0 for Radio. Both TV and FM Radio mode are working.
