The hwmgr module is responsible for messages sent to GAUDI F/W that are not common to all habanalabs ASICs. In GAUDI, we provide the user a simplified mode of controlling the ASIC clock frequency. Instead of three different clocks, we present a single clock property that the user can configure via sysfs. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
