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 * tag 'reset-for-4.15' of git://git.pengutronix.de/git/pza/linux: reset: zx2967: use the reset-simple driver reset: stm32: use the reset-simple driver reset: socfpga: use the reset-simple driver reset: sunxi: use reset-simple driver reset: add reset-simple to unify socfpga, stm32, sunxi, and zx2967 reset: meson: remove unneeded check in meson_reset_reset reset: meson: add level reset support for GX SoC family reset: uniphier: add PXs3 reset data reset: mediatek: add reset controller dt-bindings required header for MT7622 SoC reset: socfpga: build the reset-socfpga for Stratix10 SOC reset: uniphier: add ethernet reset control support reset: socfpga: fix for 64-bit compilation ARC: reset: introduce AXS10x reset driver

+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>;
+ ....
+ };
