[SRU][J:linux-bluefield][PATCH v1 0/1] UBUNTU: SAUCE: ptm debugfs: add ddr thermal event nodes

[Jitendra Lanka]

BugLink: https://bugs.launchpad.net/bugs/2029505

SRU Justification:

[Impact]

mlxbf-ptm is a kernel driver that provides debufgs interface for system
software to monitor Bluefield devices' power and thermal management
parameters.

[Fix]

* This change adds additional debugfs nodes that provides event counter
  and throttling states of ddr thermal management state machine.

[Test Case]

* After installing the kernel module, debugfs entry at
  /sys/kernel/debug/mlxbf-ptm will be created
* monitors/status folder contains read-only parameters reported from the
  Bluefield device

[Regression Potential]

* Minimal - as these are read-only parameters that report Bluefield device
  information.

[Other]

* This code is likely to change depending on feedback we received from
  maintainers.
