Note that some embedded systems will choose to vary the AC97 link clock. The most common case is where there's a PLL on the CODEC - the CODEC will start up misclocked at whatever the input frequency it's got is and then be reclocked using register writes to configure the PLL. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
