7bff4b4d3a V4L/DVB (7393): tda827x: fixed support of tuners with LNA
Tuner refactoring broke support of tuners with LNA configurations 1 and 2
for both, analog TV and DVB-T.
Additionally, this patch initializes the saa713x gpios defined by the gpiomask
at driver init to avoid undefined stated at dvb.

db8a695658 V4L/DVB (6127): tuner: kill i2c_client interface to tuner sub-drivers
To ease the conversion of the analog tuner sub-drivers into dvb_frontend
style tuner modules, we must remove the i2c_client interface.

dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter.

This change only alters the interface between tuner.ko and the tuner
sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact.

This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv,
to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.

27487d4471 V4L/DVB (3384): Separate tv & radio freqs, fix cb/freq transmit order for tuners that need this.
- Moved MSP_SET_MATRIX to v4l2-common.h
- Fix typos and integer overflows in tea5767.c
- Split old freq field into a tv_freq and a radio_freq. Prevents
  that a radio tuner is initialized with a tv frequency or vice versa.
- When switching to radio mode initialize the tuner with the last
  used radio frequency (this was already done for the TV mode).
  As a result of these changes the tuner module now remembers the
  last set radio and TV frequencies, which is what you would expect
  to happen.
- Move out of range frequencies to the closest valid frequency as per
  v4l2 API spec.
- Fix incorrect initial radio frequency (multiplier is 16000, not 16)
- Add boundary check for out of range frequencies.
- Use new flag to check if the order of the CB and freq. depends on
  the last set frequency. That is needed for some tuners or you can
  get static as a result. The flag is added for those tuners where I know
  that the datasheet indicates that this is necessary.
- For this new check use the last set div value, not the last frequency
  as radio frequencies are always much higher due to the 16000 multiplier.
