2016-10-03IB/hns: Add & initialize "node_guid" parameter for RDMA CMLijun Ou
According to the Infiniband spec, NodeGUID uniquely identifies a node. This must be initialized to some unique value. This patch adds the support to the HNS RoCE driver to fetch the NodeGUID value from DT or ACPI and then use this value to initialize the node_guid parameter of IB device. This value shall be used by RDMA CM.

2016-10-03IB/hns: Register HNS RoCE Driver get_netdev() with IB CoreLijun Ou
This patch adds get_netdev() function to the IB device. This shall be used to fetch netdev corresponding to the port number. This function would be called by IB core(Generic CM Agent) for example, when the RDMA connection is being established.

2016-08-25IB/hns: Add support of ACPI to the Hisilicon RoCE driverSalil
This patch is meant to add support of ACPI to the Hisilicon RoCE driver. Changes done are primarily meant to detect the type and then either use DT specific or ACPI spcific functions. Where ever possible, this patch tries to make use of Unified Device Property Interface APIs to support both DT and ACPI through single interface. This patch depends upon HNS ethernet driver to Reset RoCE. This function within HNS ethernet driver has also been enhanced to support ACPI and is part of other accompanying patch with this patch-set.

2016-08-22IB/hns: Fix return value check in hns_roce_get_cfg()Wei Yongjun
In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <weiyj.lk@gmail.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
