 Tony,

Who do you expect to make that code merge? Do you expect us to mechanically merge RX51 PPA API patch with the existing generic OMAP PPA API code putting #ifdefs all over the place? Not that it is impossible, but the only real piece of HW I have here is n900, so I just can't be sure the code will still work on the other platforms besides RX51, once the code modified. Please, advice on how to proceed.

Regards,
Ivo
