+

+ - Roger Quadros <rogerq@ti.com>
+
+description:
+ The TI OMAP Control PHY module is a hardware block within the system
+ control module (SCM) of Texas Instruments OMAP SoCs. It provides
+ centralized control over power, configuration, and auxiliary features
+ for multiple on-chip PHYs. This module is essential for proper PHY
+ operation in power-constrained embedded systems.

-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-pcie" - for pcie to support external clock for pcie and to
- set PCS delay value.
- e.g. PCIE PHY in DRA7x
- "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 : register ranges as listed in the reg-names property
- - reg-names: "otghs_control" for control-phy-otghs
- "power", "pcie_pcs" and "control_sma" for control-phy-pcie
- "power" for all other types
-
-omap_control_usb: omap-control-usb@4a002300 {
- compatible = "ti,control-phy-otghs";
- reg = <0x4a00233c 0x4>;
- reg-names = "otghs_control";
-};
-
-TI PIPE3 PHY
-
-Required properties:
- - compatible: Should be "ti,phy-usb3", "ti,phy-pipe3-sata" or
- "ti,phy-pipe3-pcie. "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.
- * "dpll_ref" - external dpll ref clk
- * "dpll_ref_m2" - external dpll ref clk
- * "phy-div" - divider for apll
- * "div-clk" - apll clock
-
-Optional properties:
- - id: If there are multiple instance of the same type, in order to
- differentiate between each instance "id" can be used (e.g., multi-lane PCIe
- PHY). If "id" is not provided, it is set to default value of '1'.
- - syscon-pllreset: Handle to system control region that contains the
- CTRL_CORE_SMA_SW_0 register and register offset to the CTRL_CORE_SMA_SW_0
- register that contains the SATA_PLL_SOFT_RESET bit. Only valid for sata_phy.
- - syscon-pcs : phandle/offset pair. Phandle to the system control module and the
- register offset to write the PCS delay value.
-
-Deprecated properties:
- - ctrl-module : phandle of the control module used by PHY driver to power on
- the PHY.
-
-Recommended properties:
- - syscon-phy-power : phandle/offset pair. Phandle to the system control
- module and the register offset to power on/off the PHY.
-
-This is usually a subnode of ocp2scp to which it is connected.
