Merge tag 'usb-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big USB/PHY driver patches for 4.20-rc1 Lots of USB changes in here, primarily in these areas: - typec updates and new drivers - new PHY drivers - dwc2 driver updates and additions (this old core keeps getting added to new devices.) - usbtmc major update based on the industry group coming together and working to add new features and performance to the driver. - USB gadget additions for new features - USB gadget configfs updates - chipidea driver updates - other USB gadget updates - USB serial driver updates - renesas driver updates - xhci driver updates - other tiny USB driver updates All of these have been in linux-next for a while with no reported issues" * tag 'usb-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (229 commits) usb: phy: ab8500: silence some uninitialized variable warnings usb: xhci: tegra: Add genpd support usb: xhci: tegra: Power-off power-domains on removal usbip:vudc: BUG kmalloc-2048 (Not tainted): Poison overwritten usbip: tools: fix atoi() on non-null terminated string USB: misc: appledisplay: fix backlight update_status return code phy: phy-pxa-usb: add a new driver usb: host: add DT bindings for faraday fotg2 usb: host: ohci-at91: fix request of irq for optional gpio usb/early: remove set but not used variable 'remain_length' usb: typec: Fix copy/paste on typec_set_vconn_role() kerneldoc usb: typec: tcpm: Report back negotiated PPS voltage and current USB: core: remove set but not used variable 'udev' usb: core: fix memory leak on port_dev_path allocation USB: net2280: Remove ->disconnect() callback from net2280_pullup() usb: dwc2: disable power_down on rockchip devices usb: gadget: udc: renesas_usb3: add support for r8a77990 dt-bindings: usb: renesas_usb3: add bindings for r8a77990 usb: gadget: udc: renesas_usb3: Add r8a774a1 support USB: serial: cypress_m8: remove set but not used variable 'iflag' ...

+ROCKCHIP HDMI PHY WITH INNO IP BLOCK
+
+Required properties:
+ - compatible : should be one of the listed compatibles:
+ * "rockchip,rk3228-hdmi-phy",
+ * "rockchip,rk3328-hdmi-phy";
+ - reg : Address and length of the hdmi phy control register set
+ - clocks : phandle + clock specifier for the phy clocks
+ - clock-names : string, clock name, must contain "sysclk" for system
+ control and register configuration, "refoclk" for crystal-
+ oscillator reference PLL clock input and "refpclk" for pclk-
+ based refeference PLL clock input.
+ - #clock-cells: should be 0.
+ - clock-output-names : shall be the name for the output clock.
+ - interrupts : phandle + interrupt specified for the hdmiphy interrupt
+ - #phy-cells : must be 0. See ./phy-bindings.txt for details.
+
+Optional properties for rk3328-hdmi-phy:
+ - nvmem-cells = phandle + nvmem specifier for the cpu-version efuse
+ - nvmem-cell-names : "cpu-version" to read the chip version, required
+ for adjustment to some frequency settings
+
+Example:
+ hdmi_phy: hdmi-phy@12030000 {
+ compatible = "rockchip,rk3228-hdmi-phy";
+ reg = <0x12030000 0x10000>;
+ #phy-cells = <0>;
+ clocks = <&cru PCLK_HDMI_PHY>, <&xin24m>, <&cru DCLK_HDMIPHY>;
+ clock-names = "sysclk", "refoclk", "refpclk";
+ #clock-cells = <0>;
+ clock-output-names = "hdmi_phy";
+ status = "disabled";
+ };
+
+Then the PHY can be used in other nodes such as:
+
+ hdmi: hdmi@200a0000 {
+ compatible = "rockchip,rk3228-dw-hdmi";
+ ...
+ phys = <&hdmi_phy>;
+ phy-names = "hdmi";
+ ...
+ };
