-8. Board File Initialization
-
-Certain board file initialization is necessary in order to get a reference
-to the PHY in the case of non-dt boot.
-Say we have a single device that implements 3 PHYs that of USB, SATA and PCIe,
-then in the board file the following initialization should be done.
-
-struct phy_consumer consumers[] = {
- PHY_CONSUMER("dwc3.0", "usb"),
- PHY_CONSUMER("pcie.0", "pcie"),
- PHY_CONSUMER("sata.0", "sata"),
-};
-PHY_CONSUMER takes 2 parameters, first is the device name of the controller
-(PHY consumer) and second is the port name.
-
-struct phy_init_data init_data = {
- .consumers = consumers,
- .num_consumers = ARRAY_SIZE(consumers),
-};
-
-static const struct platform_device pipe3_phy_dev = {
- .name = "pipe3-phy",
- .id = -1,
- .dev = {
- .platform_data = {
- .init_data = &init_data,
- },
- },
-};
-
-then, while doing phy_create, the PHY driver should pass this init_data
- phy_create(dev, ops, pdata->init_data);
-
-and the controller driver (phy consumer) should pass the port name along with
-the device to get a reference to the PHY
- phy_get(dev, "pcie");
+8. PHY Mappings
+
+In order to get reference to a PHY without help from DeviceTree, the framework
+offers lookups which can be compared to clkdev that allow clk structures to be
+bound to devices. A lookup can be made be made during runtime when a handle to
+the struct phy already exists.
+
+The framework offers the following API for registering and unregistering the
+lookups.
+
+int phy_create_lookup(struct phy *phy, const char *con_id, const char *dev_id);
+void phy_remove_lookup(struct phy *phy, const char *con_id, const char *dev_id);
