Message-ID<r2uYy-41S-11@gated-at.bofh.it>
From: Буди Романто, AreMa Inc <knightrider@are.ma>

Polished driver bundle for PT3 & PX-Q3PE, two of the most powerful ISDB-S/ISDB-T receiver cards
currently available in Japan. Useless features are removed.

Main Components:
A. PT3 (2 ISDB-S + 2 ISDB-T receiver)
 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
	ISDB-T : MaxLinear CMOS Hybrid TV MxL301RF

B. PX-Q3PE (4 ISDB-S + 4 ISDB-T receiver)
 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

Буди Романто, AreMa Inc (7):
  raise adapter number limit
  add NXP tda2014x & Newport Media nm120/130/131 tuners
  drop backstabbing drivers
  Toshiba TC90522XBG quad demod (2ch OFDM + 2ch 8PSK) for PT3 & PXQ3PE
  MaxLinear MxL301RF ISDB-T tuner
  Sharp QM1D1C0042 ISDB-S tuner
  PCI bridge driver for PT3 & PXQ3PE

Message-ID<r2v8g-45p-55@gated-at.bofh.it>
In reply to#1334640
