1 TI PHY: DT DOCUMENTATION FOR PHYs in TI PLATFORMs
6 - compatible: Should be one of
7 "ti,control-phy-otghs" - if it has otghs_control mailbox register as on OMAP4.
8 "ti,control-phy-usb2" - if it has Power down bit in control_dev_conf register
9 e.g. USB2_PHY on OMAP5.
10 "ti,control-phy-pipe3" - if it has DPLL and individual Rx & Tx power control
11 e.g. USB3 PHY and SATA PHY on OMAP5.
12 "ti,control-phy-usb2-dra7" - if it has power down register like USB2 PHY on
14 "ti,control-phy-usb2-am437" - if it has power down register like USB2 PHY on
16 - reg : Address and length of the register set for the device. It contains
17 the address of "otghs_control" for control-phy-otghs or "power" register
19 - reg-names: should be "otghs_control" control-phy-otghs and "power" for
22 omap_control_usb: omap-control-usb@4a002300 {
23 compatible = "ti,control-phy-otghs";
24 reg = <0x4a00233c 0x4>;
25 reg-names = "otghs_control";
31 - compatible: Should be "ti,omap-usb2"
32 - reg : Address and length of the register set for the device.
33 - #phy-cells: determine the number of cells that should be given in the
34 phandle while referencing this phy.
37 - ctrl-module : phandle of the control module used by PHY driver to power on
40 This is usually a subnode of ocp2scp to which it is connected.
43 compatible = "ti,omap-usb2";
44 reg = <0x4a0ad080 0x58>;
45 ctrl-module = <&omap_control_usb>;
52 - compatible: Should be "ti,phy-usb3". "ti,omap-usb3" is deprecated.
53 - reg : Address and length of the register set for the device.
54 - reg-names: The names of the register addresses corresponding to the registers
56 - #phy-cells: determine the number of cells that should be given in the
57 phandle while referencing this phy.
60 - ctrl-module : phandle of the control module used by PHY driver to power on
63 This is usually a subnode of ocp2scp to which it is connected.
66 compatible = "ti,phy-usb3";
67 reg = <0x4a084400 0x80>,
70 reg-names = "phy_rx", "phy_tx", "pll_ctrl";
