TI PHY: DT DOCUMENTATION FOR PHYs in TI PLATFORMs OMAP CONTROL PHY Required properties: - compatible: Should be one of "ti,control-phy-otghs" - if it has otghs_control mailbox register as on OMAP4. "ti,control-phy-usb2" - if it has Power down bit in control_dev_conf register e.g. USB2_PHY on OMAP5. "ti,control-phy-pipe3" - if it has DPLL and individual Rx & Tx power control e.g. USB3 PHY and SATA PHY on OMAP5. "ti,control-phy-usb2-dra7" - if it has power down register like USB2 PHY on DRA7 platform. "ti,control-phy-usb2-am437" - if it has power down register like USB2 PHY on AM437 platform. - reg : Address and length of the register set for the device. It contains the address of "otghs_control" for control-phy-otghs or "power" register for other types. - reg-names: should be "otghs_control" control-phy-otghs and "power" for other types. omap_control_usb: omap-control-usb@4a002300 { compatible = "ti,control-phy-otghs"; reg = <0x4a00233c 0x4>; reg-names = "otghs_control"; }; OMAP USB2 PHY Required properties: - compatible: Should be "ti,omap-usb2" - reg : Address and length of the register set for the device. - #phy-cells: determine the number of cells that should be given in the phandle while referencing this phy. - clocks: a list of phandles and clock-specifier pairs, one for each entry in clock-names. - clock-names: should include: * "wkupclk" - wakeup clock. * "refclk" - reference clock (optional). Optional properties: - ctrl-module : phandle of the control module used by PHY driver to power on the PHY. This is usually a subnode of ocp2scp to which it is connected. usb2phy@4a0ad080 { compatible = "ti,omap-usb2"; reg = <0x4a0ad080 0x58>; ctrl-module = <&omap_control_usb>; #phy-cells = <0>; clocks = <&usb_phy_cm_clk32k>, <&usb_otg_ss_refclk960m>; clock-names = "wkupclk", "refclk"; }; TI PIPE3 PHY Required properties: - compatible: Should be "ti,phy-usb3" or "ti,phy-pipe3-sata". "ti,omap-usb3" is deprecated. - reg : Address and length of the register set for the device. - reg-names: The names of the register addresses corresponding to the registers filled in "reg". - #phy-cells: determine the number of cells that should be given in the phandle while referencing this phy. - clocks: a list of phandles and clock-specifier pairs, one for each entry in clock-names. - clock-names: should include: * "wkupclk" - wakeup clock. * "sysclk" - system clock. * "refclk" - reference clock. Optional properties: - ctrl-module : phandle of the control module used by PHY driver to power on the PHY. This is usually a subnode of ocp2scp to which it is connected. usb3phy@4a084400 { compatible = "ti,phy-usb3"; reg = <0x4a084400 0x80>, <0x4a084800 0x64>, <0x4a084c00 0x40>; reg-names = "phy_rx", "phy_tx", "pll_ctrl"; ctrl-module = <&omap_control_usb>; #phy-cells = <0>; clocks = <&usb_phy_cm_clk32k>, <&sys_clkin>, <&usb_otg_ss_refclk960m>; clock-names = "wkupclk", "sysclk", "refclk"; }; |
