[git pull] habanalabs pull request for kernel 5.7

[Oded Gabbay]

Hello Greg,

This is the pull request for habanalabs driver for kernel 5.7.

It mainly contains improvements to MMU, hwmon sensors and a new debugfs
interface to improve debug speed when reading large internal memories.

Please see the tag message for more details on what this pull request
contains.

Thanks,
Oded

  habanalabs: fix pm manual->auto in GOYA (2020-03-24 10:54:17 +0200)

----------------------------------------------------------------
This tag contains the following changes for kernel 5.7:

- MMU code improvements that includes:
  - Flush MMU TLB cache only once, at the end of mapping/unmapping
    function, instead of flushing after mapping of every page.
  - Add future ASIC support by splitting properties of ASIC capabilities
    regarding mapping of host memory to regular and huge pages.

- Add debugfs interface to write and read 64-bit values from the device's
  memory/registers. Previously the driver provided interface for 32-bit
  values and this will allow the user to debug much more quickly. We saw it
  gives a boost of around 1.5 - 1.7 when reading internal memories.

- Support temperature offset via sysfs as defined in
  https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface

- Display historical maximum of various sensors.

- Print to kernel log when clock throttling occurs to due breach of power
  or thermal envelope. Also prints when clock throttling is finished
  (clock is back to optimal).

- Fix bug when moving from manual to auto power-management mode.

- Print a message ("unsupported device") to kernel log in case a GAUDI device
  is recognized.

- Small bug fixes and minor improvements to code.
