Dear Mauro

Thanks for your replying.

I am checking your comments and linux/media codes.

I need to discuss with our members about our driver's structure.
Especially,
1. SPI

2.Tuner & Demodulator

Our codes for tuner and demodulator driver of user-space are encapsulated in order to optimize tuner control sequence.

I will send comments and additional questions after we have internal discussion.

Thanks,
Takiguchi
