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

Pull ARM SoC driver updates from Arnd Bergmann:
 "This branch contains platform-related driver updates for ARM and
  ARM64, these are the areas that bring the changes:

  New drivers:

   - driver support for Renesas R-Car V3M (R8A77970)

   - power management support for Amlogic GX

   - a new driver for the Tegra BPMP thermal sensor

   - a new bus driver for Technologic Systems NBUS

  Changes for subsystems that prefer to merge through arm-soc:

   - the usual updates for reset controller drivers from Philipp Zabel,
     with five added drivers for SoCs in the arc, meson, socfpa,
     uniphier and mediatek families

   - updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
     Heiner Kallweit and Lorenzo Pieralisi

  Changes specific to some ARM-based SoC

   - the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on
     ARM as well

   - several changes for power management on Broadcom SoCs

   - various improvements on Qualcomm, Broadcom, Amlogic, Atmel,
     Mediatek

   - minor Cleanups for Samsung, TI OMAP SoCs"

[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
  because the R8A77970 driver is missing a header file that came from
  that pull.

  The fact that this got merged afterwards only fixes it at this point,
  and bisection of that driver will fail if/when you walk into the
  history of that driver.           - Linus ]

+Qualcomm Remote File System Memory binding
+
+This binding describes the Qualcomm remote filesystem memory, which serves the
+purpose of describing the shared memory region used for remote processors to
+access block device data using the Remote Filesystem protocol.
+
+- compatible:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be:
+		    "qcom,rmtfs-mem"
+
+- reg:
+	Usage: required for static allocation
+	Value type: <prop-encoded-array>
+	Definition: must specify base address and size of the memory region,
+		    as described in reserved-memory.txt
+
+- size:
+	Usage: required for dynamic allocation
+	Value type: <prop-encoded-array>
+	Definition: must specify a size of the memory region, as described in
+		    reserved-memory.txt
+
+- qcom,client-id:
+	Usage: required
+	Value type: <u32>
+	Definition: identifier of the client to use this region for buffers.
+
+- qcom,vmid:
+	Usage: optional
+	Value type: <u32>
+	Definition: vmid of the remote processor, to set up memory protection.
+
+= EXAMPLE
+The following example shows the remote filesystem memory setup for APQ8016,
+with the rmtfs region for the Hexagon DSP (id #1) located at 0x86700000.
+
+	reserved-memory {
+		#address-cells = <2>;
+		#size-cells = <2>;
+		ranges;
+
+		rmtfs@86700000 {
+			compatible = "qcom,rmtfs-mem";
+			reg = <0x0 0x86700000 0x0 0xe0000>;
+			no-map;
+
+			qcom,client-id = <1>;
+		};
+	};
