[PATCH 1/6] si2168: add ts_mode setting and move to si2168_init

[PATCH 1/6] si2168: add ts_mode setting and move to si2168_init

[Olli Salonen]

Luis Alves submitted a TS mode patch to si2168 earlier, but the patch was rejected due to a small issue. Here is a working version. Also, setting of TS mode is moved from si2168_set_frontend to si2168_init.

This patch adds the TS mode as a config option for the si2168 demod:
- ts_mode added to config struct.
- Possible (interesting) values are
   * Parallel mode = 0x06
   * Serial mode = 0x03

Currently the modules using this demod only use parallel mode. Patches for these modules later in this patch series.

[PATCH 4/6] cx23885: add i2c client handling into dvb_unregister and state

[Olli Salonen]

Prepare cx23885 driver for handling I2C client that is needed for certain demodulators and tuners (for example Si2168 and Si2157). I2C client for tuner and demod stored in state and unregistering of the I2C devices added into dvb_unregister.

[PATCH 5/6] cx23855: add frontend set voltage function into state

[Olli Salonen]

Setting the LNB voltage requires setting some GPIOs on the cx23885 with some boards before calling the actual set_voltage function in the demod driver. Add a function pointer into state for that case.

[PATCH 6/6] cx23855: add support for DVBSky T9580 DVB-C/T2/S2 tuner

[Olli Salonen]

DVBSky T9580 is a dual tuner card with one DVB-T2/C tuner and one DVB-S2 tuner. It contains the following components:

- PCIe bridge: Conexant CX23885
- Demod for terrestrial/cable: Silicon Labs Si2168-A30
- Tuner for terrestrial/cable: Silicon Labs Si2158-A20
- Demod for sat: Montage DS3103
- Tuner for sat: Montage TS2022

This patch depends on Max Nibble's patch for m88ds3103 (see patchwork 25312: https://patchwork.linuxtv.org/patch/25312/ ).

3 firmwares are needed:
- Si2168-A30 demod and Si2158-A20 tuner: same as TechnoTrend CT2-4400, https://www.mail-archive.com/linux-media@vger.kernel.org/msg76944.html
- Montage DS3103 demod: same as PCTV 461e, Antti has it on his LinuxTV project page: http://palosaari.fi/linux/v4l-dvb/firmware/M88DS3103/

IR receiver is not supported.

Values in cx23885_gpio_setup, cx23885_card_setup and dvbsky_t9580_set_voltage as well as the EEPROM read function are taken from the manufacturer provided semi-open source driver. The drivers in question are Linux GPL'd media tree drivers for cx23885 modified by Max Nibble (nibble.max@gmail.com) with proprietary tuner/demod drivers. Max is aware of this patch and has approved my use of the values in this patch.

Re: [PATCH 2/6] em28xx: add ts mode setting for PCTV 461e

PCTV 461e is satellite receiver whilst that one should be PCTV 292e. I 
will fix the type, no new patch needed.
