2021-05-08habanalabs: expose ASIC specific PLL indexBharat Jauhari1-6/+6
Currently the user cannot interpret the PLL information based on index as its exposed as an integer. This commit exposes ASIC specific PLL indexes and maps it to a generic FW compatible index.

2020-11-30habanalabs: add 'needs reset' state in driverOfir Bitton1-4/+4
The new state indicates that device should be reset in order to re-gain funcionality. This unique state can occur if reset_on_lockup is disabled and an actual lockup has occurred.

2020-07-29habanalabs: fix up absolute include instructionsGreg Kroah-Hartman1-1/+1
There's no need to try to be cute with the include file locations in the Makefile, so just specify exactly where the files are. Bonus is this fixes the problem of building with O= as well as trying to just build the subdirectory alone.

2020-05-19habanalabs: add hwmgr module for gaudiOded Gabbay1-0/+121
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>
