[PATCH 2/7] habanalabs: Use pending CS amount per ASIC

[Oded Gabbay]

From: Ofir Bitton <obitton@habana.ai>

Training schemes requires much more concurrent command submissions than
inference does. In addition, training command submissions can be completed
in a non serialized manner. Hence, we add support in which each ASIC will
be able to configure the amount of concurrent pending command submissions,
rather than use a predefined amount. This change will enhance performance
by allowing the user to add more concurrent work without waiting for the
previous work to be completed.

[PATCH 3/7] habanalabs: sync stream generic functionality

[Oded Gabbay]

From: Ofir Bitton <obitton@habana.ai>

Currently sync stream is limited only for external queues. We want to
remove this constraint by adding a new queue property dedicated for sync
stream. In addition we move the initialization and reset methods to the
common code since we can re-use them with slight changes.

[PATCH 4/7] habanalabs: Use mask instead of shift in sync stream registers

[Oded Gabbay]

From: Ofir Bitton <obitton@habana.ai>

Use proper bitfield masks instead of shifting values when configuring
packets sent to device.

[PATCH 6/7] habanalabs: align armcp_packet structure to 8 bytes

[Oded Gabbay]

Once there is a 64-bit field in a structure, GCC compiler for ARM aligns
the structure to 8 bytes. In order to avoid confusion when these
structures are being passed between CPUs from different architectures, we
explicitly align the structure to 8 bytes.

[PATCH 7/7] habanalabs: calculate trace frequency from PLL

[Oded Gabbay]

From: Adam Aharon <aaharon@habana.ai>

The profiler needs to know the PLL values for correctly showing the
profiling data. Because our firmware can use different PLL configurations,
we need to read the PLL values from the ASIC to pass them to the profiler.
