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-pcie" - for pcie to support external clock for pcie and to
14 e.g. PCIE PHY in DRA7x
15 "ti,control-phy-usb2-dra7" - if it has power down register like USB2 PHY on
17 "ti,control-phy-usb2-am437" - if it has power down register like USB2 PHY on
19 - reg : register ranges as listed in the reg-names property
20 - reg-names: "otghs_control" for control-phy-otghs
21 "power", "pcie_pcs" and "control_sma" for control-phy-pcie
22 "power" for all other types

25 compatible = "ti,control-phy-otghs";
26 reg = <0x4a00233c 0x4>;
27 reg-names = "otghs_control";
33 - compatible: Should be "ti,omap-usb2"
34 - reg : Address and length of the register set for the device.
35 - #phy-cells: determine the number of cells that should be given in the
36 phandle while referencing this phy.
37 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
39 - clock-names: should include:
40 * "wkupclk" - wakeup clock.
41 * "refclk" - reference clock (optional).
44 - ctrl-module : phandle of the control module used by PHY driver to power on
47 This is usually a subnode of ocp2scp to which it is connected.
50 compatible = "ti,omap-usb2";

55 clock-names = "wkupclk", "refclk";
61 - compatible: Should be "ti,phy-usb3", "ti,phy-pipe3-sata" or
62 "ti,phy-pipe3-pcie. "ti,omap-usb3" is deprecated.
63 - reg : Address and length of the register set for the device.
64 - reg-names: The names of the register addresses corresponding to the registers
66 - #phy-cells: determine the number of cells that should be given in the
67 phandle while referencing this phy.
68 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
70 - clock-names: should include:
71 * "wkupclk" - wakeup clock.
72 * "sysclk" - system clock.
73 * "refclk" - reference clock.
74 * "dpll_ref" - external dpll ref clk
75 * "dpll_ref_m2" - external dpll ref clk
76 * "phy-div" - divider for apll
77 * "div-clk" - apll clock
80 - ctrl-module : phandle of the control module used by PHY driver to power on
82 - id: If there are multiple instance of the same type, in order to
83 differentiate between each instance "id" can be used (e.g., multi-lane PCIe
84 PHY). If "id" is not provided, it is set to default value of '1'.
86 This is usually a subnode of ocp2scp to which it is connected.
