Merge tag 'usb-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB/PHY updates from Greg KH:
 "Here is the big set of USB and PHY driver patches for 5.2-rc1

  There is the usual set of:

   - USB gadget updates

   - PHY driver updates and additions

   - USB serial driver updates and fixes

   - typec updates and new chips supported

   - mtu3 driver updates

   - xhci driver updates

   - other tiny driver updates

  Nothing really interesting, just constant forward progress.

  All of these have been in linux-next for a while with no reported
  issues. The usb-gadget and usb-serial trees were merged a bit "late",
  but both of them had been in linux-next before they got merged here
  last Friday"

What:		Raise a uevent when a USB Host Controller has died

Date:		2019-04-17

KernelVersion:	5.2

Contact:	linux-usb@vger.kernel.org

Description:	When the USB Host Controller has entered a state where it is no

		longer functional a uevent will be raised. The uevent will

		contain ACTION=offline and ERROR=DEAD.



		Here is an example taken using udevadm monitor -p:



		KERNEL[130.428945] offline  /devices/pci0000:00/0000:00:10.0/usb2 (usb)

		ACTION=offline

		BUSNUM=002

		DEVNAME=/dev/bus/usb/002/001

		DEVNUM=001

		DEVPATH=/devices/pci0000:00/0000:00:10.0/usb2

		DEVTYPE=usb_device

		DRIVER=usb

		ERROR=DEAD

		MAJOR=189

		MINOR=128

		PRODUCT=1d6b/2/414

		SEQNUM=2168

Broadcom Stingray USB PHY



Required properties:

 - compatible : should be one of the listed compatibles

	- "brcm,sr-usb-combo-phy" is combo PHY has two PHYs, one SS and one HS.

	- "brcm,sr-usb-hs-phy" is a single HS PHY.

 - reg: offset and length of the PHY blocks registers

 - #phy-cells:

   - Must be 1 for brcm,sr-usb-combo-phy as it expects one argument to indicate

     the PHY number of two PHYs. 0 for HS PHY and 1 for SS PHY.

   - Must be 0 for brcm,sr-usb-hs-phy.



Refer to phy/phy-bindings.txt for the generic PHY binding properties



Example:

	usbphy0: usb-phy@0 {

		compatible = "brcm,sr-usb-combo-phy";

		reg = <0x00000000 0x100>;

		#phy-cells = <1>;

	usbphy2: usb-phy@20000 {

		compatible = "brcm,sr-usb-hs-phy";

		reg = <0x00020000 0x100>,

		#phy-cells = <0>;
