[PATCH] OSS: Remove dead AD1889 driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is unlike other OSS drivers, in that it has never functioned. Might
as well remove the dead code. 

Signed-off-by: Kyle McMartin <[email protected]>

Whether or not Adrian's patch is applied, this code can be removed.

-<jsm> tausq: Anyway, to set up sample rates for D to A, you just use the sample rate on the codec. For A to D, you need to set the codec always to 48K (using the split sample rate feature on the codec) and then set the resampler on the AD1889 to the sample rate you want.
-<jsm> Also, when changing the sample rate on the codec you need to power it down and re power it up for the change to take effect!
