Previously the driver used pcie_get_minimum_link() to warn when the NIC
is in a slot that can't supply as much bandwidth as the NIC could use.
pcie_get_minimum_link() can be misleading because it finds the slowest link
and the narrowest link (which may be different links) without considering
the total bandwidth of each link. For a path with a 16 GT/s x1 link and a
2.5 GT/s x16 link, it returns 2.5 GT/s x1, which corresponds to 250 MB/s of
bandwidth, not the true available bandwidth of about 1969 MB/s for a
16 GT/s x1 link.
Use pcie_print_link_status() to report PCIe link speed and possible
limitations instead of implementing this in the driver itself. This finds
the slowest link in the path to the device by computing the total bandwidth
of each link and compares that with the capabilities of the device.
The dmesg change is:
- PCI Express bandwidth of %dGT/s available
- (Speed:%s, Width: x%d, Encoding Loss:%s)
+ %u.%03u Gb/s available PCIe bandwidth (%s x%d link)
or, if the device is capable of better performance than is available in the
current slot:
- This is not sufficient for optimal performance of this card.
- For optimal performance, at least %dGT/s of bandwidth is required.
- A slot with more lanes and/or higher speed is suggested.
+ %u.%03u Gb/s available PCIe bandwidth, limited by %s x%d link at %s (capable of %u.%03u Gb/s with %s x%d link)
Note that the driver previously used dev_warn() to suggest using a
different slot, but pcie_print_link_status() uses dev_info() because if the
platform has no faster slot available, the user can't do anything about the
warning and may not want to be bothered with it.

This series contains two omap1 ams-delta GPIO clean-up patches to get
started with removal of hard-coded GPIO numbers from drivers. And then
the removal of board mach includes from drivers. The second patch mostly
touches the ams-delta audio driver but is included here because of the
removal of the latch gpios and is acked by Mark Brown.
And there are two more am437x related PM patches to save and restore
control module and timer registers for RTC only suspend mode. Looks like
the patch title for the timer changes is a bit misleading, not all the
timer code is yet living under drivers/clocksource. But I had already
pushed out the branch before I noticed this.

This patch removes the unused bt-en-1-8v regulator and moves the
bt_en_gios claim to the pm8994_gpios node.
This bt_en_gpio could have been moved to the bluetooth serial node but
instead this node declares an 'enable' gpio addressing the bt_en_gpio.
This is needed by the Qualcomm QCA6174 WLAN/BT combo chip that needs to
have the bt_en_gpio claimed even if only WLAN is used.

The property name vddpe-supply is not included in
Documentation/devicetree/bindings/pci/qcom,pcie.txt
nor in the pcie-qcom PCIe Root Complex driver.
This property name was used in an initial patchset for pcie-qcom,
but was renamed in a later revision.
Therefore, the regulator is currently never enabled, leaving us with
unoperational wlan.
Fix this by using the correct regulator property name, so that wlan
comes up correctly.

Introduce a new read/write lock that will protect statistics gathering from
netdev channels configuration changes.
e.g. when channels are being replaced (increase/decrease number of rings)
prevent statistic gathering (ndo_get_stats64) to read the statistics of
in-active channels (channels that are being closed).
Plus update channels software statistics on the fly when calling
ndo_get_stats64, and remove it from stats periodic work.

We fill SQ edge with NOPs to avoid WQEs wrap.
Here, instead of doing that in advance for the maximum possible

of WQE size (ds_cnt) before doing any writes to the WQE buffer.
When SQ work queue is fragmented (introduced in an downstream patch),
dealing with WQE wraps becomes more frequent. This change would drastically
reduce the overhead in this case.

If a TC rule needs to be split for mirroring, create two HW rules,
in the first level and the second level flow tables accordingly.
In the first level flow table, forward the packet to the mirror
port and forward the packet to the second level flow table for
further processing, eg. encap, vlan push or header re-write.
Currently the matching is repeated in both stages.
While here, simplify the setup of the vhca id valid indicator also
in the existing code.

Currently, we only support the mirred redirect TC sub-action. In order
to support flow based vport mirroring, add support to parse the mirred
mirror sub-action.
For mirroring, user-space will typically set the action order such that
the mirror port (mirror VF) sees packets as the original port (VF under
mirroring) sent them or as it will receive them.
In the general case, it means that packets are potentially sent to the
mirror port before or after some actions were applied on them. To
properly do that, we should follow on the exact action order as set for
the flow and make sure this will also be the case when we program the HW
offload.
We introduce a counter for the output ports (attr->out_count), which we
increase when parsing each mirred redirect/mirror sub-action and when
dealing with encap.
We introduce a counter (attr->mirror_count) telling us if split is
needed. If no split is needed and mirroring is just multicasting to
vport, the mirror count is zero, all the actions of the TC flow should
apply on that single HW flow.
If split is needed, the mirror count tells where to do the split, all
non-mirred tc actions should apply only after the split.
The mirror count is set while parsing the following actions encap/decap,
header re-write, vlan push/pop.

This is going to be used for flow based mirroring under the switchdev
