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
24 omap_control_usb: omap-control-usb@4a002300 {
25 compatible = "ti,control-phy-otghs";
26 reg = <0x4a00233c 0x4>;
27 reg-names = "otghs_control";
33 - compatible: Should be "ti,omap-usb2"
34 Should be "ti,dra7x-usb2-phy2" for the 2nd instance of USB2 PHY
36 - reg : Address and length of the register set for the device.
37 - #phy-cells: determine the number of cells that should be given in the
38 phandle while referencing this phy.
39 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
41 - clock-names: should include:
42 * "wkupclk" - wakeup clock.
43 * "refclk" - reference clock (optional).
45 Deprecated properties:
46 - ctrl-module : phandle of the control module used by PHY driver to power on
49 Recommended properies:
50 - syscon-phy-power : phandle/offset pair. Phandle to the system control
51 module and the register offset to power on/off the PHY.
53 This is usually a subnode of ocp2scp to which it is connected.
56 compatible = "ti,omap-usb2";
57 reg = <0x4a0ad080 0x58>;
58 ctrl-module = <&omap_control_usb>;
60 clocks = <&usb_phy_cm_clk32k>, <&usb_otg_ss_refclk960m>;
61 clock-names = "wkupclk", "refclk";
67 - compatible: Should be "ti,phy-usb3", "ti,phy-pipe3-sata" or
68 "ti,phy-pipe3-pcie. "ti,omap-usb3" is deprecated.
69 - reg : Address and length of the register set for the device.
70 - reg-names: The names of the register addresses corresponding to the registers
72 - #phy-cells: determine the number of cells that should be given in the
73 phandle while referencing this phy.
74 - clocks: a list of phandles and clock-specifier pairs, one for each entry in
76 - clock-names: should include:
77 * "wkupclk" - wakeup clock.
78 * "sysclk" - system clock.
79 * "refclk" - reference clock.
80 * "dpll_ref" - external dpll ref clk
81 * "dpll_ref_m2" - external dpll ref clk
82 * "phy-div" - divider for apll
83 * "div-clk" - apll clock
86 - id: If there are multiple instance of the same type, in order to
87 differentiate between each instance "id" can be used (e.g., multi-lane PCIe
88 PHY). If "id" is not provided, it is set to default value of '1'.
89 - syscon-pllreset: Handle to system control region that contains the
90 CTRL_CORE_SMA_SW_0 register and register offset to the CTRL_CORE_SMA_SW_0
91 register that contains the SATA_PLL_SOFT_RESET bit. Only valid for sata_phy.
92 - syscon-pcs : phandle/offset pair. Phandle to the system control module and the
93 register offset to write the PCS delay value.
95 Deprecated properties:
96 - ctrl-module : phandle of the control module used by PHY driver to power on
99 Recommended properies:
100 - syscon-phy-power : phandle/offset pair. Phandle to the system control
101 module and the register offset to power on/off the PHY.
