This patch is meant to add support of ACPI to the Hisilicon RoCE

driver.

quoted

Following changes have been made in the driver(s):

Patch 1/2: HNS Ethernet Driver: changes to support ACPI have been

done in

quoted

   the RoCE reset function part of the HNS ethernet driver. Earlier

it only

quoted

   supported DT/syscon.

Patch 2/2. HNS RoCE driver: changes done in RoCE driver are meant to

detect

quoted

   the type and then either use DT specific or ACPI spcific

functions. Where

quoted

   ever possible, this patch tries to make use of "Unified Device

Property

quoted

   Interface" APIs to support both DT and ACPI through single

interface.

quoted

NOTE 1: ACPI changes done in both of the drivers depend upon the ACPI

Table

quoted

     (DSDT and IORT tables) changes part of UEFI/BIOS. These changes

are NOT

quoted

     part of this patch-set.
NOTE 2: Reset function in Patch 1/2 depends upon the reset function

added in

quoted

     ACPI tables(basically DSDT table) part of the UEFI/BIOS. Again,

this

quoted

     change is NOT reflected in this patch-set.

I can't apply this series to my tree because the hns infiniband driver
doesn't exist in it.

Hi David,
I understand your point. This patch-set was primarily sent for Doug Ledford
and is based on his internal repository (which has been rebased on the
net-next). 

Though we were hoping, if by any chance, we can expedite the acceptance of the
below patch part of patch-set in the net-next. This might help Doug Ledford as
well later on when he pushes the already accepted RoCE driver and ACPI patches
to linux-next,

"[PATCH for-next 1/2] net: hns: Add support of ACPI to HNS driver RoCE Reset
 function"

Below HNS RoCE reset function patch has already been accepted and is part of your
net-next,
https://patchwork.kernel.org/patch/9287497/

Above ACPI support of RoCE Reset patch cleanly applies over the already accepted
patch in the link. It is not dependent on other accompanying RoCE driver ACPI
changes related patch or even the presence of the Infiniband/RoCE Driver in the
net-next repository.

Could you please suggest anything here?  

Thanks 
Salil
