Subject: [PATCH v4 3/3] arm64: dts: Add USB DT nodes for Stingray SoC
Add DT nodes for
- Two xHCI host controllers
- Two BDC Broadcom USB device controller
- Five USB PHY controllers
[xHCI0] [BDC0] [xHCI1] [BDC1]
| | | |
--------------- -----------------------
| | | | |
[SS-PHY0] [HS-PHY0] [SS-PHY1] [HS-PHY2] [HS-PHY1]
[SS-PHY0/HS-PHY0] and [SS-PHY1/HS-PHY1] are combo PHYs has one SS and
one HS PHYs. [HS-PHY2] is a single HS PHY.
xHCI use SS-PHY to detect SS devices and HS-PHY to detect HS/FS/LS
devices. BDC use SS-PHY in SS mode and HS-PHY in HS mode.
xHCI0 port1 is SS-PHY0, port2 is HS-PHY0.
xHCI1 port1 is SS-PHY1, port2 is HS-PHY2 and port3 is HS-PHY1.
