[PATCH 0/3] Disable dynamic load balancing and support fixed balancing

[Andi Shyti <andi.shyti@linux.intel.com>]

Hi,

This series aims to disable the CCS hardware load balancing, as recommended by
hardware directives in Wa_16016805146.

In the meantime, we need to define and support a fixed CCS mode of balancing
that can be configured by the user.

Thanks,
Andi
