Merge tag 'usb-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB and PHY updates from Greg KH:
 "Here is the big USB pull request for 4.18-rc1.

  Lots of stuff here, the highlights are:

   - phy driver updates and new additions

   - usual set of xhci driver updates

   - normal set of musb updates

   - gadget driver updates and new controllers

   - typec work, it's getting closer to getting fully out of the staging
     portion of the tree.

   - lots of minor cleanups and bugfixes.

  All of these have been in linux-next for a while with no reported
  issues"

Description:
In some cases, we care about time-to-active for devices
connected on a specific port (e.g. non-standard USB port like
pogo pins), where the device to be connected is known in
advance, and behaves well according to the specification.
This attribute is a bit-field that controls the behavior of
a specific port:
- Bit 0 of this field selects the "old" enumeration scheme,
as it is considerably faster (it only causes one USB reset
instead of 2).
The old enumeration scheme can also be selected globally
using /sys/module/usbcore/parameters/old_scheme_first, but
it is often not desirable as the new scheme was introduced to
increase compatibility with more devices.
- Bit 1 reduces TRSTRCY to the 10 ms that are required by the
USB 2.0 specification, instead of the 50 ms that are normally
used to help make enumeration work better on some high speed
devices.

MediaTek XS-PHY binding
--------------------------
The XS-PHY controller supports physical layer functionality for USB3.1
GEN2 controller on MediaTek SoCs.
Required properties (controller (parent) node):
- compatible : should be "mediatek,<soc-model>-xsphy", "mediatek,xsphy",
soc-model is the name of SoC, such as mt3611 etc;
when using "mediatek,xsphy" compatible string, you need SoC specific
ones in addition, one of:
- "mediatek,mt3611-xsphy"
- #address-cells, #size-cells : should use the same values as the root node
- ranges: must be present
Optional properties (controller (parent) node):
- reg : offset and length of register shared by multiple U3 ports,
exclude port's private register, if only U2 ports provided,
shouldn't use the property.
- mediatek,src-ref-clk-mhz : u32, frequency of reference clock for slew rate
calibrate
- mediatek,src-coef : u32, coefficient for slew rate calibrate, depends on
SoC process
Required nodes : a sub-node is required for each port the controller
provides. Address range information including the usual
'reg' property is used inside these nodes to describe
the controller's topology.
Required properties (port (child) node):
- reg : address and length of the register set for the port.
- clocks : a list of phandle + clock-specifier pairs, one for each
entry in clock-names
- clock-names : must contain
"ref": 48M reference clock for HighSpeed analog phy; and 26M
reference clock for SuperSpeedPlus analog phy, sometimes is
24M, 25M or 27M, depended on platform.
- #phy-cells : should be 1
cell after port phandle is phy type from:
- PHY_TYPE_USB2
- PHY_TYPE_USB3
The following optional properties are only for debug or HQA test
Optional properties (PHY_TYPE_USB2 port (child) node):
- mediatek,eye-src : u32, the value of slew rate calibrate
- mediatek,eye-vrt : u32, the selection of VRT reference voltage
- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
- mediatek,efuse-intr : u32, the selection of Internal Resistor
Optional properties (PHY_TYPE_USB3 port (child) node):
- mediatek,efuse-intr : u32, the selection of Internal Resistor
- mediatek,efuse-tx-imp : u32, the selection of TX Impedance
- mediatek,efuse-rx-imp : u32, the selection of RX Impedance
