Merge tag 'phy-for-4.15_v1' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-next
Kishon writes: phy: for 4.15 *) Add support in phy core to perform phy calibration *) Return NULL for optional PHY's even if CONFIG_GENERIC_PHY is not selected *) Add USB Phy driver for Broadcom STB SoCs *) Add support to force mediatek PHY with USB OTG function to enter a specific mode *) Calibrate rockchip-typec PHY according to docs *) Enable dual route feature for sun4i-usb in V3s SoC *) Use dr_mode dt property to enable otg capability in rcar-gen3-usb2 *) Add driver data to specify dedicated otg pins in rcar-gen3-usb2 driver *) Configure the RX equalizer of brcm-sata PHY *) Update pcie phy settings for ti-pipe3 phy *) Add set_mode callback in qcom-ufs-qmp-14nm phy *) Use PHY callbacks in phy-qcom-ufs instead of export APIs Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

+Broadcom STB USB PHY
+
+Required properties:
+ - compatible: brcm,brcmstb-usb-phy
+ - reg: two offset and length pairs.
+ The first pair specifies a manditory set of memory mapped
+ registers used for general control of the PHY.
+ The second pair specifies optional registers used by some of
+ the SoCs that support USB 3.x
+ - #phy-cells: Shall be 1 as it expects one argument for setting
+ the type of the PHY. Possible values are:
+ - PHY_TYPE_USB2 for USB1.1/2.0 PHY
+ - PHY_TYPE_USB3 for USB3.x PHY
+
+Optional Properties:
+- clocks : clock phandles.
+- clock-names: String, clock name.
+- brcm,ipp: Boolean, Invert Port Power.
+ Possible values are: 0 (Don't invert), 1 (Invert)
+- brcm,ioc: Boolean, Invert Over Current detection.
+ Possible values are: 0 (Don't invert), 1 (Invert)
+NOTE: one or both of the following two properties must be set
+- brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
+- brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
+- dr_mode: String, PHY Device mode.
+ Possible values are: "host", "peripheral ", "drd" or "typec-pd"
+ If this property is not defined, the phy will default to "host" mode.
+
+Example:
+
+usbphy_0: usb-phy@f0470200 {
+ reg = <0xf0470200 0xb8>,
+ <0xf0471940 0x6c0>;
+ compatible = "brcm,brcmstb-usb-phy";
+ #phy-cells = <1>;
+ dr_mode = "host"
+ brcm,ioc = <1>;
+ brcm,ipp = <1>;
+ brcm,has-xhci;
+ brcm,has-eohci;
+ clocks = <&usb20>, <&usb30>;
+ clock-names = "sw_usb", "sw_usb3";
+};
