This patchset is mainly used to enable usb2 function on poplar board.
Jiancheng Xue (4):
clk: hisilicon: add usb2 clocks for hi3798cv200 SoC
dt-bindings: phy-hisi-inno-usb2: add support for hisi-inno-usb2 phy
arm64: dts: hisilicon: add usb2 controller and phy nodes for poplar
board.
arm64: defconfig: enable some drivers and configs for
hi3798cv200-poplar board.
Pengcheng Li (1):
phy: add inno-usb2-phy driver for hi3798cv200 SoC

+HiSilicon INNO USB2 PHY
+-----------------------
+Required properties:
+- compatible: Should be one of the following strings:
+ "hisilicon,inno-usb2-phy",
+ "hisilicon,hi3798cv200-usb2-phy",
+- #phy-cells: Must be 0
+- hisilicon,peripheral-syscon: Phandle of syscon used to control phy.
+- clocks: Phandle and clock specifier pair for reference clock utmi_refclk.
+- resets: List of phandle and reset specifier pairs for each reset signal in
+reset-names.
+- reset-names: Should be "por_rst" and "test_rst". The test_rst only
+exists in some of SOCs, so it is optional.
+
+Phy node can include up to four subnodes. Each subnode represents one port.
+The required properties of port node are as follows:
+- clocks: Phandle and clock specifier pair for utmi_clock.
+- resets: List of phandle and reset specifier pairs for port reset and utmi reset.
+- reset-names: List of reset signal names. Should be "port_rst" and "utmi_rst"
+
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
+Example:
+usb_phy: phy {
+ compatible = "hisilicon,inno_usb2_phy";
+ #phy-cells = <0>;
+ hisilicon,peripheral-syscon = <&peri_ctrl>;
+ clocks = <&crg USB2_REF_CLK>;
+ resets = <&crg 0xb4 2>;
+ reset-names = "por_rst";

+ resets = <&crg 0xb4 5>, <&crg 0xb4 1>;

Here a property should be added to supply offsets of phy specific registers
in the above peripheral syscon. I will modify this in the next version.
