So I guess my S952 is too old? :-( How hard would >it be to add support for it? If it is m88ts2020, there is a tuner driver "ts2020" in "dvb-frontends" directory. If fail to load m88ts2022 driver, then try to load ts2020 driver. m88ts2022 driver is an i2c driver, but ts2020 is traditional dvb-attach driver. Please check the other code using ts2020 for reference.
