From b400f09246247e2c55b116bd7b71da4fb0cb19dc Mon Sep 17 00:00:00 2001 From: Dmitri Belimov Date: Tue, 30 Mar 2010 03:02:17 -0300 Subject: [PATCH] V4L/DVB: Fix default state Beholder H6 tuner The hybrid tuner FMD1216MEX_MK3 after cold start has disabled IF. This tuner has internal I2C switch. This switch switch I2C bus between DVB-T and IF part. Default state is DVB-T. When module saa7134 is load it can't find IF tda9887 and disable analog TV mode. Sets internal I2C switch of the tuner to IF by send special value to the tuner as for receive analog TV from low band. It can be usefule for other cards. I didn't set configure a tuner by a tuner model because this tuner can have different I2C address. May be we can do it later after discuss for more robust support a tuners.
