synopsys DWC3 CORE

DWC3- USB3 CONTROLLER

Required properties:
 - compatible: must be "snps,dwc3"
 - reg : Address and length of the register set for the device
 - interrupts: Interrupts used by the dwc3 controller.

Optional properties:
 - usb-phy : array of phandle for the PHY device.  The first element
   in the array is expected to be a handle to the USB2/HS PHY and
   the second element is expected to be a handle to the USB3/SS PHY
 - phys: from the *Generic PHY* bindings
 - phy-names: from the *Generic PHY* bindings
 - tx-fifo-resize: determines if the FIFO *has* to be reallocated.
 - snps,usb3_lpm_capable: determines if platform is USB3 LPM capable
 - snps,disable_scramble_quirk: true when SW should disable data scrambling.
	Only really useful for FPGA builds.
 - snps,has-lpm-erratum: true when DWC3 was configured with LPM Erratum enabled
 - snps,lpm-nyet-threshold: LPM NYET threshold
 - snps,u2exit_lfps_quirk: set if we want to enable u2exit lfps quirk
 - snps,u2ss_inp3_quirk: set if we enable P3 OK for U2/SS Inactive quirk
 - snps,req_p1p2p3_quirk: when set, the core will always request for
			P1/P2/P3 transition sequence.
 - snps,del_p1p2p3_quirk: when set core will delay P1/P2/P3 until a certain
			amount of 8B10B errors occur.
 - snps,del_phy_power_chg_quirk: when set core will delay PHY power change
			from P0 to P1/P2/P3.
 - snps,lfps_filter_quirk: when set core will filter LFPS reception.
 - snps,rx_detect_poll_quirk: when set core will disable a 400us delay to start
			Polling LFPS after RX.Detect.
 - snps,tx_de_emphasis_quirk: when set core will set Tx de-emphasis value.
 - snps,tx_de_emphasis: the value driven to the PHY is controlled by the
			LTSSM during USB3 Compliance mode.
 - snps,dis_u3_susphy_quirk: when set core will disable USB3 suspend phy.
 - snps,dis_u2_susphy_quirk: when set core will disable USB2 suspend phy.
 - snps,is-utmi-l1-suspend: true when DWC3 asserts output signal
			utmi_l1_suspend_n, false when asserts utmi_sleep_n
 - snps,hird-threshold: HIRD threshold

This is usually a subnode to DWC3 glue to which it is connected.
