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 > There aren't many DVB drivers that aren't either PCI or USB. > There's one at drivers/media/mmc/siano/smssdio.c, but I guess this is not the > best example. ST is working on upstreaming drivers for some of their SoCs. They're > placing their drivers under drivers/media/platform/sti. Maybe this could help you more on that. 2.Tuner & Demodulator > At the DVB frontend, the tuner and demodulators should be implemented on different > drivers, even when both are encapsulated on the same silicon. > By using two drivers, it makes easier to review the code. It also helps to better > encapsulate the functions on each part of the chip. 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.
