Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver updates from Olof Johansson:
 "Some of the larger changes this merge window:

   - Removal of drivers for Exynos5440, a Samsung SoC that never saw
     widespread use.

   - Uniphier support for USB3 and SPI reset handling

   - Syste control and SRAM drivers and bindings for Allwinner platforms

   - Qualcomm AOSS (Always-on subsystem) reset controller drivers

   - Raspberry Pi hwmon driver for voltage

   - Mediatek pwrap (pmic) support for MT6797 SoC"

+Device tree bindings for Allwinner A64 DE2 bus
+
+The Allwinner A64 DE2 is on a special bus, which needs a SRAM region (SRAM C)
+to be claimed for enabling the access.
+
+Required properties:
+
+ - compatible:		Should contain "allwinner,sun50i-a64-de2"
+ - reg:			A resource specifier for the register space
+ - #address-cells:	Must be set to 1
+ - #size-cells:		Must be set to 1
+ - ranges:		Must be set up to map the address space inside the
+			DE2, for the sub-blocks of DE2.
+ - allwinner,sram:	the SRAM that needs to be claimed
+
+Example:
+
+	de2@1000000 {
+		compatible = "allwinner,sun50i-a64-de2";
+		reg = <0x1000000 0x400000>;
+		allwinner,sram = <&de2_sram 1>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges = <0 0x1000000 0x400000>;
+
+		display_clocks: clock@0 {
+			compatible = "allwinner,sun50i-a64-de2-clk";
+			reg = <0x0 0x100000>;
+			clocks = <&ccu CLK_DE>,
+				 <&ccu CLK_BUS_DE>;
+			clock-names = "mod",
+				      "bus";
+			resets = <&ccu RST_BUS_DE>;
+			#clock-cells = <1>;
+			#reset-cells = <1>;
+		};
+	};
