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" * tag 'usb-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (263 commits) Revert "xhci: Reset Renesas uPD72020x USB controller for 32-bit DMA issue" xhci: Add quirk to zero 64bit registers on Renesas PCIe controllers xhci: Allow more than 32 quirks usb: xhci: force all memory allocations to node selftests: add test for USB over IP driver USB: typec: fsusb302: no need to check return value of debugfs_create_dir() USB: gadget: udc: s3c2410_udc: no need to check return value of debugfs_create functions USB: gadget: udc: renesas_usb3: no need to check return value of debugfs_create functions USB: gadget: udc: pxa27x_udc: no need to check return value of debugfs_create functions USB: gadget: udc: gr_udc: no need to check return value of debugfs_create functions USB: gadget: udc: bcm63xx_udc: no need to check return value of debugfs_create functions USB: udc: atmel_usba_udc: no need to check return value of debugfs_create functions USB: dwc3: no need to check return value of debugfs_create functions USB: dwc2: no need to check return value of debugfs_create functions USB: core: no need to check return value of debugfs_create functions USB: chipidea: no need to check return value of debugfs_create functions USB: ehci-hcd: no need to check return value of debugfs_create functions USB: fhci-hcd: no need to check return value of debugfs_create functions USB: fotg210-hcd: no need to check return value of debugfs_create functions USB: imx21-hcd: no need to check return value of debugfs_create functions ...

+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
