This tag contains habanalabs driver changes for v5.11-rc1:

- Add support for ability to perform collective stream sync. This is basically
  a synchronization between compute and network streams.

- Add initialization of NIC QMANs and security configuration. This is a
  pre-requisite for upstreaming the NIC ETH and RDMA code.

- Add option to scrub all internal memory (SRAM and DRAM) when the user
  closes the file-descriptor

- Support new firmware that provide enhanced device security. This includes
  many changes that basically amounts to moving certain configurations to
  the firmware and stop reading registers directly and instead receiving the
  information from the firmware. For example:
  - Retrieve HBM ECC error information
  - Retrieve PLL configuration
  - Configure of internal credits, rate-limitation

- Support new firmware that performs the GAUDI device reset instead of the
  driver. The driver now asks the firmware to do it.

- Some changes were done as Pre-requisite for future ASICs support:
  - Add option to put the device's PCI MMU page tables on the host memory.
  - Support loading multiple types of firmware.
  - Adding option to user to inquire about usage counter of Command buffer.

- Support taking timestamp of Command Submission when it completes and
  providing it to the user.

- Change aggregate cs counters to atomic and fix the cs counters structure
  to support addition of new counters in the future

- Update email address nad git repo of the driver in MAINTAINERS

- Many small bug fixes and improvements, such as:
  - Refactoring in MMU code to move code from ASIC-dependant files to
    common code
  - Minimize driver prints when no errors occur
  - Using enums, defines instead of hard-coded values
  - Refactoring of Command Submission flow to make it more readable now that
    we have multiple types of Command Submissions.
