Merge tag 'usb-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY driver updates from Greg KH:
 "Here are the large set of USB and PHY driver updates for 5.8-rc1.

  Nothing huge, just lots of little things:

   - USB gadget fixes and additions all over the place

   - new PHY drivers

   - PHY driver fixes and updates

   - XHCI driver updates

   - musb driver updates

   - more USB-serial driver ids added

   - various USB quirks added

   - thunderbolt minor updates and fixes

   - typec updates and additions

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

* Renesas R-Car generation 3 USB 2.0 PHY
This file provides information on what the device node for the R-Car generation
3, RZ/G1C, RZ/G2 and RZ/A2 USB 2.0 PHY contain.
Required properties:
- compatible: "renesas,usb2-phy-r7s9210" if the device is a part of an R7S9210
SoC.
"renesas,usb2-phy-r8a77470" if the device is a part of an R8A77470
SoC.
"renesas,usb2-phy-r8a774a1" if the device is a part of an R8A774A1
SoC.
"renesas,usb2-phy-r8a774b1" if the device is a part of an R8A774B1
SoC.
"renesas,usb2-phy-r8a774c0" if the device is a part of an R8A774C0
SoC.
"renesas,usb2-phy-r8a7795" if the device is a part of an R8A7795
SoC.
"renesas,usb2-phy-r8a7796" if the device is a part of an R8A7796
SoC.
"renesas,usb2-phy-r8a77965" if the device is a part of an
R8A77965 SoC.
"renesas,usb2-phy-r8a77990" if the device is a part of an
R8A77990 SoC.
"renesas,usb2-phy-r8a77995" if the device is a part of an
R8A77995 SoC.
"renesas,rcar-gen3-usb2-phy" for a generic R-Car Gen3, RZ/G2 or
RZ/A2 compatible device.
When compatible with the generic version, nodes must list the
SoC-specific version corresponding to the platform first
followed by the generic version.
- reg: offset and length of the partial USB 2.0 Host register block.
- clocks: clock phandle and specifier pair(s).
- #phy-cells: see phy-bindings.txt in the same directory, must be <1> (and
using <0> is deprecated).
The phandle's argument in the PHY specifier is the INT_STATUS bit of controller:
- 1 = USBH_INTA (OHCI)
- 2 = USBH_INTB (EHCI)
- 3 = UCOM_INT (OTG and BC)
Optional properties:
To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
combined, the device tree node should set interrupt properties to use the
channel as USB OTG:
- interrupts: interrupt specifier for the PHY.
- vbus-supply: Phandle to a regulator that provides power to the VBUS. This
regulator will be managed during the PHY power on/off sequence.
- renesas,no-otg-pins: boolean, specify when a board does not provide proper
otg pins.
- dr_mode: string, indicates the working mode for the PHY. Can be "host",
"peripheral", or "otg". Should be set if otg controller is not used.
Example (R-Car H3):
usb-phy@ee080200 {
compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
reg = <0 0xee080200 0 0x700>;
interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cpg CPG_MOD 703>;
};
usb-phy@ee0a0200 {
compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
reg = <0 0xee0a0200 0 0x700>;
clocks = <&cpg CPG_MOD 702>;
};

This file provides information on what the device node for the R-Car generation
3 and RZ/G2 USB 3.0 PHY contain.
If you want to enable spread spectrum clock (ssc), you should use USB_EXTAL
instead of USB3_CLK. However, if you don't want to these features, you don't
need this driver.
Required properties:

R8A77965 SoC.
"renesas,rcar-gen3-usb3-phy" for a generic R-Car Gen3 or RZ/G2
compatible device.
When compatible with the generic version, nodes must list the
SoC-specific version corresponding to the platform first
followed by the generic version.
- reg: offset and length of the USB 3.0 PHY register block.
- clocks: A list of phandles and clock-specifier pairs.
- clock-names: Name of the clocks.
- The funcional clock must be "usb3-if".
- The usb3's external clock must be "usb3s_clk".
- The usb2's external clock must be "usb_extal". If you want to use the ssc,
the clock-frequency must not be 0.
- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
Optional properties:
- renesas,ssc-range: Enable/disable spread spectrum clock (ssc) by using
the following values as u32:
- 0 (or the property doesn't exist): disable the ssc
- 4980: enable the ssc as -4980 ppm
- 4492: enable the ssc as -4492 ppm
- 4003: enable the ssc as -4003 ppm
Example (R-Car H3):
usb-phy@e65ee000 {
compatible = "renesas,r8a7795-usb3-phy",
"renesas,rcar-gen3-usb3-phy";
reg = <0 0xe65ee000 0 0x90>;

Intel North Mux-Agent
=====================
Introduction
============
North Mux-Agent is a function of the Intel PMC firmware that is supported on
most Intel based platforms that have the PMC microcontroller. It's used for
configuring the various USB Multiplexer/DeMultiplexers on the system. The
platforms that allow the mux-agent to be configured from the operating system
have an ACPI device object (node) with HID "INTC105C" that represents it.
The North Mux-Agent (aka. Intel PMC Mux Control, or just mux-agent) driver
communicates with the PMC microcontroller by using the PMC IPC method
(drivers/platform/x86/intel_scu_ipc.c). The driver registers with the USB Type-C
Mux Class which allows the USB Type-C Controller and Interface drivers to
configure the cable plug orientation and mode (with Alternate Modes). The driver
also registers with the USB Role Class in order to support both USB Host and
Device modes. The driver is located here: drivers/usb/typec/mux/intel_pmc_mux.c.
Port nodes
==========
General
-------
For every USB Type-C connector under the mux-agent control on the system, there
is a separate child node under the PMC mux-agent device node. Those nodes do not
represent the actual connectors, but instead the "channels" in the mux-agent
that are associated with the connectors::
Scope (_SB.PCI0.PMC.MUX)
{
Device (CH0)
{
Name (_ADR, 0)
}
Device (CH1)
{
Name (_ADR, 1)
}
}
_PLD (Physical Location of Device)
----------------------------------
The optional _PLD object can be used with the port (the channel) nodes. If _PLD
is supplied, it should match the connector node _PLD::
Scope (_SB.PCI0.PMC.MUX)
{
Device (CH0)
{
Name (_ADR, 0)
Method (_PLD, 0, NotSerialized)
{
/* Consider this as pseudocode. */
Return (\_SB.USBC.CON0._PLD())
}
}
}
Mux-agent specific _DSD Device Properties
-----------------------------------------
Port Numbers
~~~~~~~~~~~~
In order to configure the muxes behind a USB Type-C connector, the PMC firmware
needs to know the USB2 port and the USB3 port that is associated with the
connector. The driver extracts the correct port numbers by reading specific _DSD
device properties named "usb2-port-number" and "usb3-port-number". These
properties have integer value that means the port index. The port index number
is 1's based, and value 0 is illegal. The driver uses the numbers extracted from
these device properties as-is when sending the mux-agent specific messages to
the PMC::
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package() {
Package () {"usb2-port-number", 6},
Package () {"usb3-port-number", 3},
},
})
Orientation
~~~~~~~~~~~
Depending on the platform, the data and SBU lines coming from the connector may
be "fixed" from the mux-agent's point of view, which means the mux-agent driver
should not configure them according to the cable plug orientation. This can
happen for example if a retimer on the platform handles the cable plug
orientation. The driver uses a specific device properties "sbu-orientation"
(SBU) and "hsl-orientation" (data) to know if those lines are "fixed", and to
which orientation. The value that these properties have is a string value, and
it can be one that is defined for the USB Type-C connector orientation: "normal"
or "reversed"::
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package() {
Package () {"sbu-orientation", "normal"},
Package () {"hsl-orientation", "normal"},
},
})
Example ASL
===========
The following ASL is an example that shows the mux-agent node, and two
connectors under its control::
Scope (_SB.PCI0.PMC)
{
Device (MUX)
{
Name (_HID, "INTC105C")
Device (CH0)
{
Name (_ADR, 0)
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package() {
Package () {"usb2-port-number", 6},
Package () {"usb3-port-number", 3},
Package () {"sbu-orientation", "normal"},
Package () {"hsl-orientation", "normal"},
},
})
}
Device (CH1)
{
Name (_ADR, 1)
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package() {
Package () {"usb2-port-number", 5},
Package () {"usb3-port-number", 2},
Package () {"sbu-orientation", "normal"},
Package () {"hsl-orientation", "normal"},
},
})
}
}

Enable support for the USB high-speed SNPS Femto phy on Qualcomm
chipsets. This PHY has differences in the register map compared
to the V1 variants. The PHY is paired with a Synopsys DWC3 USB
controller on Qualcomm SOCs.
