There was 2 muxed I2C adapters, one for demod tuner bus and one for internal use. Idea of internal I2C adapter was to force I2C repeater close when demod access its registers. Driver has also delayed work queue based method to close I2C repeater. After regmap conversion internal I2C adapter based repeater close left unused - only work queue method was in use. We could not use internal mux adapter method with regmap as it makes recursive regmap call, which causes deadlock as regmap has own locking. Due to that remove whole method totally. Signed-off-by:

We are consumer of DVB frontend provided by rtl28xxu module. Due to that we must use refcount to ensure none could remove rtl28xxu when we are alive (or when we are streaming, if more fine-grained refcounting is wanted). Signed-off-by:

This driver, rtl28xxu, offers frontend service for rtl2832_sdr module, thus we are producer and rtl2832_sdr module is consumer. Due to that, reference counting should be done in way rtl2832_sdr takes refrence to rtl28xxu. Remove wrong refcount. Signed-off-by:

DVB FE callback functionality went broken after I moved tuners to demod muxed I2C adapter. That happens because driver state was carried by I2C adapter and when mux is used there is one adapter more in a chain. USB adapter <-> I2C adapter <-> muxed I2C adapter Signed-off-by:

Put demod to soft reset in order to save power when sleep. That drops power usage ~30mA @5V on USB dongle I tested. In real life it does not matter much as USB IF powers off demod too, but now it is done twice - demod and USB IF. Signed-off-by:

Chips uses 8-bit register addresses with 5 pages. Extend register address by using register page as a first byte of address, defining virtual register addresses. That is common method of handling register pages and regmap also uses it. Remove page + address conversion glue which was there for regmap. Signed-off-by:

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. Signed-off-by:
