i dont see the issue here. the firmware is *optional* and does not impair basic audio output. further, the firmware is fully written/compiled/maintained by the end customer, just like the application. which means there is no "magic" here -- the end customer is the wizard.
it's a DSP,so firmware is not optional,actually there is default internal program can be used if no external firmware is downloaded,of cause, the internal program is only used to test analog audio pass-through.
If there is default firmware then even if it's not particularly useful the kernel should probably not *require* that additional firmware is provided during driver startup - the system may wish to wait until later in the boot to provide it, for example because it needs to mount media to get to the firmware or because it needs to do additional work to decide what firmware is required for the current system setup.
sorry, i was thinking this part was like the other ADI ones where the DSP is there as an enhancement. so many of my comments were tailored towards that.
there shouldnt be any problem with us providing a stub firmware with the kernel (in firmware/) that simply does a "pass through" or whatever. -mike
