gating mechanism in Gaudi. Due to how Gaudi is built, the
clock gating needs to be disabled in order to access the
registers of the TPC and MME engines. This is sometimes needed
- during debug by the user and hence the user needs this option
+ during debug by the user and hence the user needs this option.
+ The user can supply a bitmask value, each bit represents
+ a different engine to disable/enable its clock gating feature.
+ The bitmask is composed of 20 bits:
+ 0 - 7 : DMA channels
+ 8 - 11 : MME engines
+ 12 - 19 : TPC engines
+ The bit's location of a specific engine can be determined
+ using (1 << GAUDI_ENGINE_ID_*). GAUDI_ENGINE_ID_* values
+ are defined in uapi habanalabs.h file in enum gaudi_engine_id
