Commit e431e0e4 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'usb-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY fixes from Greg KH:
 "Here are a number of small USB and PHY driver fixes for 4.11-rc4.

  Nothing major here, just an bunch of small fixes, and a handfull of
  good fixes from Johan for devices with crazy descriptors. There are a
  few new device ids in here as well.

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

Broadcom USB3 phy binding for northstar plus SoC
The USB3 phy is internal to the SoC and is accessed using mdio interface.
Required mdio bus properties:
- reg: Should be 0x0 for SoC internal USB3 phy
- #address-cells: must be 1
- #size-cells: must be 0
Required USB3 PHY properties:
- compatible: should be "brcm,nsp-usb3-phy"
- reg: USB3 Phy address on SoC internal MDIO bus and it should be 0x10.
- usb3-ctrl-syscon: handler of syscon node defining physical address
of usb3 control register.
- #phy-cells: must be 0
Required usb3 control properties:
- compatible: should be "brcm,nsp-usb3-ctrl"
- reg: offset and length of the control registers
Example:
mdio@0 {
reg = <0x0>;
#address-cells = <1>;
#size-cells = <0>;
usb3_phy: usb-phy@10 {
compatible = "brcm,nsp-usb3-phy";
reg = <0x10>;
usb3-ctrl-syscon = <&usb3_ctrl>;
#phy-cells = <0>;
status = "disabled";
};
};
usb3_ctrl: syscon@104408 {
compatible = "brcm,nsp-usb3-ctrl", "syscon";
reg = <0x104408 0x3fc>;
};
