DVB driver for Earthsoft PT3, PLEX PX-Q3PE ISDB-S/T PCIE cards & PX-BCUD ISDB-S USB dongle
==========================================================================================

Status: stable

Features:
1. in addition to the real frequency:
        ISDB-S : freq. channel ID
        ISDB-T : freq# (I/O# +128), ch#, ch# +64 for CATV
2. in addition to TSID:
        ISDB-S : slot#

Supported Cards & Main components:
A. EarthSoft PT3:
1. Altera       EP4CGX15BF14C8N : customized FPGA PCI bridge
2. Toshiba      TC90522XBG      : quad demodulator (2ch OFDM + 2ch 8PSK)
3. Sharp        VA4M6JC2103     : contains 2 ISDB-S + 2 ISDB-T tuners
        ISDB-S : Sharp QM1D1C0042 RF-IC, chip ver. 0x48
        ISDB-T : MaxLinear CMOS Hybrid TV MxL301RF

B. PLEX PX-Q3PE:
1. ASICEN       ASV5220         : PCI-E bridge
2. Toshiba      TC90522XBG      : quad demodulator (2ch OFDM + 2ch 8PSK)
3. NXP Semiconductors TDA20142  : ISDB-S tuner
4. Newport Media NM120          : ISDB-T tuner
5. ASICEN       ASIE5606X8      : crypting controller

C. PLEX PX-BCUD (ISDB-S USB dongle)
1. Empia        EM28178         : USB I/F (courtesy of Nagahama Satoshi)
2. Toshiba      TC90532         : demodulator (using TC90522 driver)
3. Sharp        QM1D1C0045_2    : ISDB-S RF-IC, chip ver. 0x68

Notes:
This is a complex but smartly polished driver package containing 2 (dual head)
PCI-E bridge I/F drivers, single demodulator frontend, and 4 (quad tail) tuner drivers,
plus, simplified Nagahama's patch for PLEX PX-BCUD (ISDB-S USB dongle).
Generic registration related procedures (subdevices, frontend, etc.) summarized in
ptx_common.c are very useful also for other DVB drivers, and would be very handy if
inserted into the core (e.g. dvb_frontend.c & dvb_frontend.h).

For example, currently, the entity of struct dvb_frontend is created sometimes in
demodulators, some in tuners, or even in the parent (bridge) drivers. IMHO, this entity
should be provided by dvb_core. ptx_register_fe() included in ptx_common.c simplifies
the tasks and in fact, significantly reduces coding & kernel size.

Also, currently dvb_frontend's .demodulator_priv & .tuner_priv are of type (void *).
These should be changed to (struct i2c_client *), IMHO. Private data for demodulator
or tuner should be attached under i2c_client, using i2c_set_clientdata() for instance.

#1370781 — [media 1/6] Raise adapter number limit

Subject[media 1/6] Raise adapter number limit
Message-ID<rkgaK-6mK-43@gated-at.bofh.it>
In reply to#1370774
From: Буди Романто, AreMa Inc <knightrider@are.ma>

The current limit is too low for latest cards with 8+ tuners on a single slot.
IMHO, the most appropriate minimum default is 16.
