Commit 64d47d50be ("net: dsa: mv88e6xxx: configure interface settings
in mac_config") removed forcing of speed and duplex from
mv88e6xxx_mac_config(), where the link is forced down, and left it only
in mv88e6xxx_mac_link_up(), by which time link is unforced.
It seems that (at least on 88E6190) when changing cmode to 2500base-x,
if the link is not forced down, but the speed or duplex are still
forced, the forcing of new settings for speed & duplex doesn't take in
mv88e6xxx_mac_link_up().
Fix this by unforcing speed & duplex in mv88e6xxx_mac_link_down().

When inserting a SFP that runs at 2.5G, then the Serdes was still
configured to run at 1G. Because the config->speed was 0, and then the
speed of the serdes was not configured at all, it was using the default
value which is 1G. This patch stop calling the serdes function set_speed
and allow the serdes to figure out the speed based on the interface
type.

When listening for notifications through netlink of a new interface being
registered, sporadically, it is possible for the MAC to be read as zero.
The zero MAC address lasts a short period of time and then switches to a
valid random MAC address.
This causes problems for netd in Android, which assumes that the interface
is malfunctioning and will not use it.
In the good case we get this log:
InterfaceController::getCfg() ifName usb0
hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002
In the error case we get these logs:
InterfaceController::getCfg() ifName usb0
hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002
netd : interfaceGetCfg("usb0")
netd : interfaceSetCfg() -> ServiceSpecificException
(99, "[Cannot assign requested address] : ioctl() failed")
The reason for the issue is the order in which the interface is setup,
it is first registered through register_netdev() and after the MAC
address is set.
Fixed by first setting the MAC address of the net_device and after that
calling register_netdev().

====================
add Vertexcom MSE102x support
This patch series adds support for the Vertexcom MSE102x Homeplug GreenPHY
chips [1]. They can be connected either via RGMII, RMII or SPI to a host CPU.
These patches handles only the last one, with an Ethernet over SPI protocol
driver.
The code has been tested only on Raspberry Pi boards, but should work
on other platforms.
Changes in V3:
- drop IF_PORT_HOMEPLUG again, since it's actually not used
Changes in V2:
- improve lock handling for RX & TX path
- add new patch to introduce IF_PORT_HOMEPLUG as suggested by Andrew Lunn
- address all the comments by Jakub Kicinski, Andrew Lunn, Kernel test robot

Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen
domU to communicate with a USB device assigned to that domU. The
communication is all done via the pvUSB backend in a driver domain
(usually Dom0) which is owner of the physical device.
The pvUSB frontend is a USB hcd for a virtual USB host connector.
The code is taken from the pvUSB implementation in Xen done by Fujitsu
based on Linux kernel 2.6.18.
Changes from the original version are:
- port to upstream kernel
- put all code in just one source file
- move module to appropriate location in kernel tree
- adapt to Linux style guide
- minor code modifications to increase readability

a Xen domU and the pvUSB backend in a Xen driver domain (usually Dom0).
This header was originally provided by Fujitsu for Xen based on Linux
2.6.18.
Changes are:
- adapt to Linux kernel style guide
- use Xen namespace
- add lots of comments
- don't use kernel internal defines

Synopsys introduced a new enhancement to DWC_usb32 called Multi-Stream
Transfer (MST) to improve bulk streams performance for SuperSpeed and
SuperSpeed Plus. This enhancement allows the controller to look ahead
and process multiple bulk streams.
Previously, to initiate a bulk stream transfer, the driver has to issue
Start Transfer command and wait for the stream to complete before
initiating a new stream. As a result, the controller does not process
TRBs beyond a single stream. With the enhancement, as long as there are
new requests, the dwc3 driver can keep preparing new TRBs and the
controller can keep caching and processing them without waiting for the
transfer completion.
The programming flow is similar to regular bulk endpoint with a few
additional rules:
1) Chained TRBs of the same stream must have a matching stream ID
2) The last TRB of a stream must have CHN=0
3) All the TRBs with LST=0 must have CSP=1
Depends on the application and usage, internal tests show significant
performance improvement in UASP transfers with this enhancement.

- Remove redundant interrupt declaration for gpio-keys on board

Naming clocks is a good practice. The atmel-quadspi driver supports
an unnamed clock for the peripheral clock in order to be backward
compatible with old DTs, but it is recommended to name the clocks
on new DTs. The driver's bindings file requires the clock-names
property, so name the clock.

Microchip EEPROM 24xx1025 is like a 24c1024. The only difference
between them is that the I2C address bit used to select between the
two banks is bit 2 for the 1025 and not bit 0 as in the 1024.

Well, just one: revert commit c045ceb5a1 ("reset: tegra-bpmp: Handle
errors in BPMP response"), which exposed an issue with the Tegra194 HDA
controller reset. BPMP response error handling will be reinstated once
there's a fix for the HDA issue.
