The MiPHY365x is a Generic PHY which can serve various SATA or PCIe
devices. It has 2 ports which it can use for either; both SATA, both
PCIe or one of each in any configuration.

+STMicroelectronics STi MIPHY365x PHY binding
+============================================
+
+This binding describes a miphy device that is used to control PHY hardware
+for SATA and PCIe.
+
+Required properties:
+- compatible: Should be "st,miphy365x-phy"
+- #phy-cells: Should be 2 (See second example)
+ First cell is the port number; MIPHY_PORT_{0,1}
+ Second cell is device type; MIPHY_TYPE_{SATA,PCI}
+- 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"
+ Options are; sata{0,1} and pcie{0,1} (See first example)
+- st,syscfg : Should be a phandle of the system configuration register group
+ which contain the SATA, PCIe mode setting bits
+
+Optional properties:
+- 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@0 {
+ compatible = "st,miphy365x-phy";
+ #phy-cells = <2>;
+ reg = <0xfe382000 0x100>,
+ <0xfe38a000 0x100>,
+ <0xfe394000 0x100>,
+ <0xfe804000 0x100>;
+ reg-names = "sata0", "sata1", "pcie0", "pcie1";
+ st,syscfg= <&syscfg_rear>;
+ };
+
+Specifying phy control of devices
+=================================
+
+Device nodes should specify the configuration required in their "phys"
+property, containing a phandle to the miphy device node, a port number
+and a device type.
+
+Example:
+
+#include <dt-bindings/phy/phy-miphy365x.h>
+
+ sata0: sata@fe380000 {
+ ...
+ phys = <&miphy365x_phy MIPHY_PORT_0 MIPHY_TYPE_SATA>;
+ ...
+ };
