2015-02-03[media] rtl2832: remove unneeded software reset from init()Antti Palosaari1-15/+0
There is no need to do software reset on init() as it is done a bit later on end of set_frontend(). Software reset usually means restarting (resetting to starting point) chip internal state machine (FSM). Naturally it is done after all parameters are programmed.

2015-02-03[media] rtl2832: define more demod lock statusesAntti Palosaari1-4/+2
Demod lock flags are derived from demod state machine states. States are running from 1 to 11, where highest state 11 means demod is fully locked and streaming. Naturally smaller state numbers means there is some partial locks. Define now state 10 as missing synch and lock.

2015-02-03[media] rtl2830: implement own I2C lockingAntti Palosaari2-7/+39
Own I2C locking is needed due to two special reasons: 1) Chips uses multiple register pages/banks on single I2C slave. Page is changed via I2C register access. 2) Chip offers muxed/gated I2C adapter for tuner. Gate/mux is controlled by I2C register access. Due to these reasons, I2C locking did not fit very well.
