[PATCH 00/13] si2157: Analog tuning and optimizations

[Brad Love <brad@nextdimension.cc>]

This series mainly enables analog tuning in the si2157
driver. Some various optimizations are included as well,
along with the dots connected to allow devices with
TUNER_ABSENT to utilize an analog frontend on two different
bridges. Finally two missing statistics are added to get
signal strength and CNR on a tuner and demod respectively.

Summary:
- Enable tuner status flags
- Check tuner status flags
- Some si2141 init
- String cleanup and register labeling
- The analog tuning functions in si2157
- A function to wait for set_*params to complete
- Enable analog fe on TUNER_ABSENT devices in cx231xx and cx23885
- Include some signal strength DVBv5 stats

Now the two patches that 'Add i2c device analog tuner support'
I would like comment on. It looks quite ugly to have big case
statements identifying the TUNER_ABSENT models that have analog.
There is nothing unique done in the blocks, mostly. Right now
there is only a few models, but the addition of more would become
a bit excessive.

Instead of the case statement should a board profile field be
added to the two affected drivers? Something like .has_i2c_analog_fe ?
