Pull ARM SoC driver updates from Arnd Bergmann:
 "This contains driver changes that are tightly connected to SoC
  specific code. Aside from smaller cleanups and bug fixes, here is a
  list of the notable changes.

  New device drivers:

   - The Turris Mox router has a new "moxtet" bus driver for its
     on-board pluggable extension bus. The same platform also gains a
     firmware driver.

   - The Samsung Exynos family gains a new Chipid driver exporting using
     the soc device sysfs interface

   - A similar socinfo driver for Qualcomm Snapdragon chips.

   - A firmware driver for the NXP i.MX DSP IPC protocol using shared
     memory and a mailbox

  Other changes:

   - The i.MX reset controller driver now supports the NXP i.MX8MM chip

   - Amlogic SoC specific drivers gain support for the S905X3 and A311D
     chips

   - A rework of the TI Davinci framebuffer driver to allow important
     cleanups in the platform code

   - A couple of device drivers for removed ARM SoC platforms are
     removed. Most of the removals were picked up by other maintainers,
     this contains whatever was left"

+Turris Mox Moxtet GPIO expander via Moxtet bus
+
+Required properties:
+ - compatible		: Should be "cznic,moxtet-gpio".
+ - gpio-controller	: Marks the device node as a GPIO controller.
+ - #gpio-cells		: Should be two. For consumer use see gpio.txt.
+
+Other properties are required for a Moxtet bus device, please refer to
+Documentation/devicetree/bindings/bus/moxtet.txt.
+
+Example:
+
+	moxtet_sfp: gpio@0 {
+		compatible = "cznic,moxtet-gpio";
+		gpio-controller;
+		#gpio-cells = <2>;
+		reg = <0>;
+	}
