The consensus that I thought we had reached was to let 83xx specify the interrupt in the controller node (to make things simple for a driver using the shared summary register rather than registering four handlers for the same IRQ), but require that it also be in the channel node, and that if there is an interrupt in the controller node, that it be the same as in all the channels. > My sound driver doesn't use Extended Mode, > but it does check for "fsl,8610-dma-channel".

Sure it'd be nice, but it's not possible without going back in time and convincing the hardware people to make them 100% compatible. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
