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.
35 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
37 - clock-names: should include:
38 * "wkupclk" - wakeup clock.
39 * "refclk" - reference clock (optional).
42 - ctrl-module : phandle of the control module used by PHY driver to power on
45 This is usually a subnode of ocp2scp to which it is connected.
48 compatible = "ti,omap-usb2";
49 reg = <0x4a0ad080 0x58>;

52 clocks = <&usb_phy_cm_clk32k>, <&usb_otg_ss_refclk960m>;
53 clock-names = "wkupclk", "refclk";
59 - compatible: Should be "ti,phy-usb3" or "ti,phy-pipe3-sata".
60 "ti,omap-usb3" is deprecated.
61 - reg : Address and length of the register set for the device.
62 - reg-names: The names of the register addresses corresponding to the registers
64 - #phy-cells: determine the number of cells that should be given in the
65 phandle while referencing this phy.
66 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
68 - clock-names: should include:
69 * "wkupclk" - wakeup clock.
70 * "sysclk" - system clock.
71 * "refclk" - reference clock.
74 - ctrl-module : phandle of the control module used by PHY driver to power on
77 This is usually a subnode of ocp2scp to which it is connected.
