New device support
* adi,admv1013
  - New driver for this wideband microwave upconverter including dt-bindings
    and some device specific ABI due to the need to describe phase calibrations
    of a differential channel on both i and q phases. Previously we could
    do differential or i/q but not both on the same channel. The driver
    ABI uses a workaround for core support which will do until we know if
    this is a common requirement for which a more generic solution is
    needed.

Add register sequences for PCIe + QSGMII PHY multilink configuration.
PHY configuration for multi-link operation is done in two steps.
e.g. Consider a case for a 4 lane PHY with PCIe using 2 lanes and QSGMII
other 2 lanes. Sierra PHY has 2 PLLs, viz. PLLLC and PLLLC1. So in this
case, PLLLC is used for PCIe and PLLLC1 is used for QSGMII.

PHY is configured in two steps as described below.

[1] For first step, the register values are selected as
    [TYPE_PCIE][TYPE_QSGMII][ssc].
    This will configure PHY registers associated for PCIe involving PLLLC
    registers and registers for first 2 lanes of PHY.
[2] In second step, the register values are selected as
    [TYPE_QSGMII][TYPE_PCIE][ssc].
    This will configure PHY registers associated for QSGMII involving
    PLLLC1 registers and registers for other 2 lanes of PHY.

This completes the PHY configuration for multilink operation.

Oded writes:

This tag contains habanalabs driver changes for v5.17:

- Support reset-during-reset. In case the f/w notifies the driver
  that the f/w is going to reset the device, the driver should
  support that even if it is in the middle of doing another
  reset

- Support events from f/w that arrive during device resets.
  These events would be ignored which is bad as critical errors
  would not be reported and treated by the driver.

- Don't kill processes that hold the control device open during
  hard-reset of the device. The control device operations can't
  crash if done during hard-reset. And usually, only monitoring
  applications are using the control device, so killing them
  defies their purpose.

- Fix handling of hwmon nodes when working with legacy f/w

- Change the compute context pointer to be boolean. This pointer
  was abused by multiple code paths that wanted fast access to
  the compute context structure.

- Add uapi to fetch historical errors. This is necessary as errors
  sometimes result in hard-reset where the user application is
  being terminated.

- Optimize GAUDI's MMU cache invalidation.

- Add support for loading the latest f/w.

- Add uapi to fetch HBM replacement and pending rows information.

- Multiple bug fixes to the reset code.

This patch fixes issue in which we have timeout for multi-CS although
the CS in the list actually completed.

Example scenario (the two threads marked as WAIT for the thread that
handles the wait_for_multi_cs and CMPL as the thread that signal
completion for both CS and multi-CS):
1. Submit CS with sequence X
2. [WAIT]: call wait_for_multi_cs with single CS X
3. [CMPL]: CS X do invoke complete_all for both CS and multi-CS
           (multi_cs_completion_done still false)
4. [WAIT]: enter poll_fences, reinit the completion and find the CS
           as completed when asking on the fence but multi_cs_done is
	   still false it returns that no CS actually completed
5. [CMPL]: set multi_cs_handling_done as true
6. [WAIT]: wait for completion but no CS to awake the wait context
           and hence wait till timeout

Solution: if CS detected as completed in poll_fences but multi_cs_done
          is still false invoke complete_all to the multi-CS completion
	  and so it will not go to sleep in wait_for_completion but
	  rather will have a "second chance" to wait for
	  multi_cs_completion_done.

Currently the cq counters are allocated in userspace memory,
and mapped by the driver to the device address space.

A new requirement that is part of new future API related to this one,
requires that cq counters will be allocated in kernel memory.

We leverage the existing cb_create API with KERNEL_MAPPED flag set to
allocate this memory.

That way we gain two things:
1. The memory cannot be freed while in use since it's protected
by refcount in driver.

2. No need to wake up the user thread upon each interrupt from CQ,
because the kernel has direct access to the counter. Therefore,
it can make comparison with the target value in the interrupt
handler and wake up the user thread only if the counter reaches the
target value. This is instead of waking the thread up to copy counter
value from user then go sleep again if target value wasn't reached.

By the original design we assumed that if we "miss" multi CS completion
it is of no severe consequence as we'll just call wait_for_multi_cs
again.

Sequence of events for such scenario:
1. user submit CS with sequence N
2. user calls wait for multi-CS with only CS #N in the list
3. the multi CS call starts with poll of the CSs but find that none
   completed (while CS #N did not completed yet)
4. now, multi CS #N complete but multi CS CTX was not yet created for
   the above multi-CS. so, attempt to complete multi-CS fails (as no
   multi CS CTX exist)
5. wait_for_multi_cs call now does init_wait_multi_cs_completion (and
   for this create the multi-CS CTX)
6. wait_for_multi_cs wits on completion but will not get one as CS #N
   already completed

To fix the issue we initialize the multi-CS CTX prior polling the
fences.

This patch attempts, where possible, to keep definitions that can serve
multiple MMU versions (but that are not tightly bound with specific MMU
arch) in the mmu_general header file (e.g. different definitions for
number of HOPs).

Otherwise, move MMU version specific definitions (e.g. HOPs masks and
shifts) to the specific MMU version file.

As we allow soft-reset to be performed only on inference devices,
having the sysfs nodes may cause a confusion. Hence, we remove those
nodes on training ASICs.
