PATCH 2/2 Add a driver for Earthsoft PT1

Add a driver for Earthsoft PT1

Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S and ISDB-T demodulators.

This card has neither MPEG decoder nor conditional access module onboard. It transmits only compressed and possibly encrypted MPEG data over the PCI bus, so you need an external software decoder and a decrypter to watch TV on your computer.

This driver is originally developed by Tomoaki Ishikawa <[email protected]> by reverse engineering.

Committed, thanks. Please take a look at the ISDB-T API recently added. It would be good to support it on all ISDB-T drivers:
