+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 : Should be a phandle of the system configuration register group
+ which contain the SATA, PCIe mode setting bits
+
+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:
+ - MIPHY_TYPE_SATA
+ - MIPHY_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
+ - syscfg: To specify the syscfg based config register
+
+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>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ phy_port0: port@fe382000 {
+ reg = <0xfe382000 0x100>, <0xfe394000 0x100>, <0x824 0x4>;
+ reg-names = "sata", "pcie", "syscfg";
+ #phy-cells = <1>;
+ st,sata-gen = <3>;
+ };
+
+ phy_port1: port@fe38a000 {
+ reg = <0xfe38a000 0x100>, <0xfe804000 0x100>, <0x828 0x4>;;
+ 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-miphy365x.h>
+
+ sata0: sata@fe380000 {
+ ...
+ phys = <&phy_port0 MIPHY_TYPE_SATA>;
+ ...
