Merge tag 'reset-for-4.15' of git://git.pengutronix.de/git/pza/linux into next/drivers

Pull "Reset controller changes for v4.15" from Philipp Zabel:

- add ARC AX10x support,
  merged from a separate branch that is also included in the ARC tree
- add Stratix10 support via socfpga
- unify socfpga, stm32, sunxi, and zx2967 into simple-reset driver
- add Meson GX reset level control and remove an unneeded check
- add Uniphier PXs3 and ethernet reset controls
- add MT7622 reset control dt-bindings header

+Binding for the AXS10x reset controller
+
+This binding describes the ARC AXS10x boards custom IP-block which allows
+to control reset signals of selected peripherals. For example DW GMAC, etc...
+This block is controlled via memory-mapped register (AKA CREG) which
+represents up-to 32 reset lines.
+
+As of today only the following lines are used:
+ - DW GMAC - line 5
+
+This binding uses the common reset binding[1].
+
+[1] Documentation/devicetree/bindings/reset/reset.txt
+
+Required properties:
+- compatible: should be "snps,axs10x-reset".
+- reg: should always contain pair address - length: for creg reset
+  bits register.
+- #reset-cells: from common reset binding; Should always be set to 1.
+
+Example:
+	reset: reset-controller@11220 {
+		compatible = "snps,axs10x-reset";
+		#reset-cells = <1>;
+		reg = <0x11220 0x4>;
+	};
+
+Specifying reset lines connected to IP modules:
+	ethernet@.... {
+		....
+		resets = <&reset 5>;
+		....
+	};
