-STMicroelectronics STi MIPHY365x PHY binding
-============================================
-
-This binding describes a miphy device that is used to control PHY hardware
-for SATA and PCIe.
-
-Required properties (controller (parent) node):
-- compatible : Should be "st,miphy365x-phy"
-- st,syscfg : Phandle / integer array property. Phandle of sysconfig group
- containing the miphy registers and integer array should contain
- an entry for each port sub-node, specifying the control
- register offset inside the sysconfig group.
-
-Required nodes : A sub-node is required for each channel the controller
- provides. Address range information including the usual
- 'reg' and 'reg-names' properties are used inside these
- nodes to describe the controller's topology. These nodes
- are translated by the driver's .xlate() function.
-
-Required properties (port (child) node):
-- #phy-cells : Should be 1 (See second example)
- Cell after port phandle is device type from:
- - PHY_TYPE_SATA
- - PHY_TYPE_PCI
-- reg : Address and length of register sets for each device in
- "reg-names"
-- reg-names : The names of the register addresses corresponding to the
- registers filled in "reg":
- - sata: For SATA devices
- - pcie: For PCIe devices
-
-Optional properties (port (child) node):
-- st,sata-gen : Generation of locally attached SATA IP. Expected values
- are {1,2,3). If not supplied generation 1 hardware will
- be expected
-- st,pcie-tx-pol-inv : Bool property to invert the polarity PCIe Tx (Txn/Txp)
-- st,sata-tx-pol-inv : Bool property to invert the polarity SATA Tx (Txn/Txp)
-
-Example:
-
- miphy365x_phy: miphy365x@fe382000 {
- compatible = "st,miphy365x-phy";
- st,syscfg = <&syscfg_rear 0x824 0x828>;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges;
-
- phy_port0: port@fe382000 {
- reg = <0xfe382000 0x100>, <0xfe394000 0x100>;
- reg-names = "sata", "pcie";
- #phy-cells = <1>;
- st,sata-gen = <3>;
- };
-
- phy_port1: port@fe38a000 {
- reg = <0xfe38a000 0x100>, <0xfe804000 0x100>;;
- reg-names = "sata", "pcie", "syscfg";
- #phy-cells = <1>;
- st,pcie-tx-pol-inv;
- };
- };
-
-Specifying phy control of devices
-=================================
-
-Device nodes should specify the configuration required in their "phys"
-property, containing a phandle to the phy port node and a device type.
-
-Example:
-
-#include <dt-bindings/phy/phy.h>
-
- sata0: sata@fe380000 {
- ...
- phys = <&phy_port0 PHY_TYPE_SATA>;
- ...
- };
