Well, the reset default is 0 (as stated on page 44) and set_hw_params() is the only location where this value is written. So if it's never written with a different value, it should always be set to its default, no?
Not all systems use a static SYSCLK rate - sometimes systems will select the rate based on their current usage. If the system has previously had to configure it then the register won't be at the default value any more.
Ok, I didn't consider that. New version of the patch attached which resets AIC3X_PLL_PROGA_REG and AIC3X_SAMPLE_RATE_SEL_REG to appropriate values in case the PLL setup is skipped.
