I prepared a patch for the mpu401_uart driver, with proposed changes. The fundamental "higlights":
-No API change needed. snd_mpu_uart401_new() can be maintained as is.
Drivers that use some other means of io, just overwrite mpu->write and mpu->read after calling snd_mpu_uart401_new() with driver specific code, just as the command port offset is handled. This lets keep Hardware dependent and hardware indepedent code separated.
-Build in support for PORT I/O (default) and MMIO (MPU401_HW_MMIO).
I would like to know your thoughts, if you accept it, reject it, or want to send it to hell, etc :-)
Best Regards
Manuel Jander.
