Hi,
This patch series fixes several bugs in the PLL driver preventing a proper
set_rate on the PLL clk.
It also enables propagation of set_rate request on the USB clk in order to
configure the PLL rate according to the USB block requirement (48 MHz).
Note that existing kernels, relying on the PLL configuration made by the
the bootloader should not be impacted by this bug, but others (those
directly booting from at91bootstrap or not enabling USB support in the
bootloader) will be.
This bug was reported by Gaël, who's directly booting the kernel from the
bootstrap.
Best Regards,
Boris
