设备树

设备树节点含义，

 - 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; supported names are "usb2-phy" or "usb3-phy".

例子，

&pinctrl0 {pinctrl_usb0_default: usb0-default {mux {groups = "usb0_0_grp";function = "usb0";};conf {groups = "usb0_0_grp";slew-rate = <1>;/*SLEW_RATE_SLOW*/io-standard = <1>;/*IO_STANDARD_LVCMOS18*/};conf-rx {pins = "MIO52", "MIO53", "MIO55";bias-high-impedance;};conf-tx {pins = "MIO54", "MIO56", "MIO57", "MIO58", "MIO59","MIO60", "MIO61", "MIO62", "MIO63";bias-disable;};};
};&usb0 {pinctrl-names = "default";pinctrl-0 = <&pinctrl_usb0_default>;
};&dwc3_0 {dr_mode = "host";snps,usb3_lpm_capable;phy-names = "usb3-phy";phys = <&lane0 4 0 2 100000000>;/*2->PHY_TYPE_USB3=4*/maximum-speed = "super-speed";
};

读写ULPI PHY寄存器

zynqmp通过GUSB2PHYACC_ULPI寄存器来访问ULPI PHY，地址，

0xFE20C280 (USB3_0_XHCI)
0xFE30C280 (USB3_1_XHCI)

SMSC 3320

在 USB 控制器针对 USB 2.0 配置以及启用待机／重启状态时，该控制器会通过发送 ULPI PHY 单命令来选择终止和收发器。在 PHY 要求这些通过两个单独的命令发送时，这会导致系统挂起。GUCTL1（0x0000C11C）寄存器的位 10 需要设置为 1，以便实现与 USB 2.0 PHY 设备（SMSC 3320）的更佳互操作性，以及预防高速设备的挂起/恢复有任何问题（06/13/2017 AR# 67667）。

UAS

UAS在2018.2还不稳定，等待改进，建议使用usb-storage (BOT) driver。
