  habanalabs/gaudi: don't enable clock gating on DMA5 (2021-02-08 18:20:08 +0200)

----------------------------------------------------------------
This tag contains the following changes for 5.12-rc1:

- Improve communication protocol with device CPU CP application.
  The change prevents random (rare) out-of-sync errors.

- Notify F/W to start sending events only after initialization of
  device is done. This fixes the issue where fatal events were received
  but ignored.

- Fix integer handling (static analysis warning).

- Always fetch HBM ECC errors from F/W (if available).

- Minor fix in GAUDI-specific initialization code.
