      net: hns: Add support of ACPI to HNS driver RoCE Reset function · d605916b
      Salil authored
      In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network
      Subsystem and is dependent upon DSAF module. Therefore, certain
      functions like RESET are exposed through the common registers of
      HNS DSAF module which are memory-mapped by the HNS driver and
      currently can only be accessed through DT/syscon interface.
      
      This patch adds the support of ACPI to the existing RoCE reset
      function in the HNS driver(please refer NOTE 2). Hisilicon RoCE
      driver (please refer NOTE 1) shall call this reset function during
      probe time to reset the RoCE Engine.
      
      The HNS Reset function indirectly ends up in calling the _DSM()
      function part of the DSDT ACPI Table. Actual reset functionality
      for ACPI is implemented within the ACPI DSDT Table which also has
      been enhanced to support this change.
      
      Support of ACPI in the HNS RoCE driver shall be pushed through a
      different accompanying below patch:
      "IB/hns: Add support of ACPI to the Hisilicon RoCE Driver"
      
      NOTE 1: HNS RoCE driver has already been accepted by its maintainer
      Doug Ledford<dledford@redhat.com>. Please refer below link:
      https://www.spinics.net/lists/linux-rdma/msg38850.html
      
      NOTE 2: RoCE reset function patch has been accepted and now is
      part of the net-next:
