Pull clk updates from Stephen Boyd:
 "The diff is dominated by the Allwinner A10/A20 SoCs getting converted
  to the sunxi-ng framework. Otherwise, the heavy hitters are various
  drivers for SoCs like AT91, Amlogic, Renesas, and Rockchip. There are
  some other new clk drivers in here too but overall this is just a
  bunch of clk drivers for various different pieces of hardware and a
  collection of non-critical fixes for clk drivers.

  New Drivers:
   - Allwinner R40 SoCs
   - Renesas R-Car Gen3 USB 2.0 clock selector PHY
   - Atmel AT91 audio PLL
   - Uniphier PXs3 SoCs
   - ARC HSDK Board PLLs
   - AXS10X Board PLLs
   - STMicroelectronics STM32H743 SoCs

  Removed Drivers:
   - Non-compiling mb86s7x support

  Updates:
   - Allwinner A10/A20 SoCs converted to sunxi-ng framework
   - Allwinner H3 CPU clk fixes
   - Renesas R-Car D3 SoC
   - Renesas V2H and M3-W modules
   - Samsung Exynos5420/5422/5800 audio fixes
   - Rockchip fractional clk approximation fixes
   - Rockchip rk3126 SoC support within the rk3128 driver
   - Amlogic gxbb CEC32 and sd_emmc clks
   - Amlogic meson8b reset controller support
   - IDT VersaClock 5P49V5925/5P49V6901 support
   - Qualcomm MSM8996 SMMU clks
   - Various 'const' applications for struct clk_ops
   - si5351 PLL reset bugfix
   - Uniphier audio on LD11/LD20 and ethernet support on LD11/LD20/Pro4/PXs2
   - Assorted Tegra clk driver fixes"

+* Renesas R-Car USB 2.0 clock selector
+
+This file provides information on what the device node for the R-Car USB 2.0
+clock selector.
+
+If you connect an external clock to the USB_EXTAL pin only, you should set
+the clock rate to "usb_extal" node only.
+If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
+is not needed because this is default setting. (Of course, you can set the
+clock rates to both "usb_extal" and "usb_xtal" nodes.
+
+Case 1: An external clock connects to R-Car SoC
+	+----------+   +--- R-Car ---------------------+
+	|External  |---|USB_EXTAL ---> all usb channels|
+	|clock     |   |USB_XTAL                       |
+	+----------+   +-------------------------------+
+In this case, we need this driver with "usb_extal" clock.
+
+Case 2: An oscillator connects to R-Car SoC
+	+----------+   +--- R-Car ---------------------+
+	|Oscillator|---|USB_EXTAL -+-> all usb channels|
+	|          |---|USB_XTAL --+                   |
+	+----------+   +-------------------------------+
+In this case, we don't need this selector.
+
+Required properties:
+- compatible: "renesas,r8a7795-rcar-usb2-clock-sel" if the device is a part of
+	      an R8A7795 SoC.
+	      "renesas,r8a7796-rcar-usb2-clock-sel" if the device if a part of
+	      an R8A7796 SoC.
+	      "renesas,rcar-gen3-usb2-clock-sel" for a generic R-Car Gen3
+	      compatible device.
+
+	      When compatible with the generic version, nodes must list the
+	      SoC-specific version corresponding to the platform first
+	      followed by the generic version.
+
+- reg: offset and length of the USB 2.0 clock selector register block.
+- clocks: A list of phandles and specifier pairs.
+- clock-names: Name of the clocks.
+ - The functional clock must be "ehci_ohci"
+ - The USB_EXTAL clock pin must be "usb_extal"
+ - The USB_XTAL clock pin must be "usb_xtal"
+- #clock-cells: Must be 0
+
+Example (R-Car H3):
+
+	usb2_clksel: clock-controller@e6590630 {
+		compatible = "renesas,r8a77950-rcar-usb2-clock-sel",
+			     "renesas,rcar-gen3-usb2-clock-sel";
+		reg = <0 0xe6590630 0 0x02>;
+		clocks = <&cpg CPG_MOD 703>, <&usb_extal>, <&usb_xtal>;
+		clock-names = "ehci_ohci", "usb_extal", "usb_xtal";
+		#clock-cells = <0>;
+	};
