Hi Uri, The patch looks sane, but I'd like to have a better picture of the Siano device, to better understand this interface. The basic question is: why do we need an SDIO interface for a DVB device? For what reason this interface is needed?
The answer is relatively easy: Some hosts only have a SDIO interface, so no USB, no PCI, no I2C, no MPEG2-streaming interface. So, the device has to provide a SDIO interface in order to read and write register and to make DMAs to get the data to the host. Think of your cell-phone, or your PDA.
There are some/a lot of vendors who use Linux in their commercial mobile-TV product and there are some component-makers like Siano, who are supporting those vendors through GPL drivers.
