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)
