We run into this problem with the PLLB on the at91: ohci-at91 disables the PLLB when going to suspend. The slowclock code however tries to do the same: It saves the PLLB register value and when restoring the value during resume, it waits for the PLLB to lock again. However the PLL will never lock and the loop would run into its timeout because the slowclock code just stored and restored an empty register. This fixes the problem by only restoring PLLA/PLLB when they were enabled at suspend time.
