[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.

Some video adapters have more than one tuner inside. This patch
|
||||
enables support for using more than one tuner. This is required
|
||||
for some cards to allow tunning both video and radio.
|
||||
It also improves I2C autodetection for these cards.
|
||||
|
||||
Only few tuners currently is supporting this. More to come.
|
||||
|
||||
It is safe to say 'Y' here even if your card has only one I2C tuner.
