Pull more ARM SoC updates from Olof Johansson:
 "A few updates that we merged late but are low risk for regressions for
  other platforms (and a few other straggling patches):

   - I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in
     here. They're for a driver for the PL353 SRAM controller and a
     build fix for the qualcomm scm driver.

   - A new platform, RDA Micro RDA8810PL (Cortex-A5 w/ integrated
     Vivante GPU, 256MB RAM, Wifi). This includes some acked
     platform-specific drivers (serial, etc). This also include DTs for
     two boards with this SoC, OrangePi 2G and OrangePi i86.

   - i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K
     video playback offload). This is the first i.MX 64-bit SoC.

   - Some minor updates to Samsung boards (adding a few peripherals in
     DTs).

   - Small rework for SMP bootup on STi platforms.

   - A couple of TEE driver fixes.

   - A couple of new config options (bcm2835 thermal, Uniphier MDMAC)
     enabled in defconfigs"

+Device tree bindings for ARM PL353 static memory controller
+
+PL353 static memory controller supports two kinds of memory
+interfaces.i.e NAND and SRAM/NOR interfaces.
+The actual devices are instantiated from the child nodes of pl353 smc node.
+
+Required properties:
+- compatible		: Should be "arm,pl353-smc-r2p1", "arm,primecell".
+- reg			: Controller registers map and length.
+- clock-names		: List of input clock names - "memclk", "apb_pclk"
+			  (See clock bindings for details).
+- clocks		: Clock phandles (see clock bindings for details).
+- address-cells		: Must be 2.
+- size-cells		: Must be 1.
+
+Child nodes:
+ For NAND the "arm,pl353-nand-r2p1" and for NOR the "cfi-flash" drivers are
+supported as child nodes.
+
+for NAND partition information please refer the below file
+Documentation/devicetree/bindings/mtd/partition.txt
+
+Example:
+	smcc: memory-controller@e000e000
+			compatible = "arm,pl353-smc-r2p1", "arm,primecell";
+			clock-names = "memclk", "apb_pclk";
+			clocks = <&clkc 11>, <&clkc 44>;
+			reg = <0xe000e000 0x1000>;
+			#address-cells = <2>;
+			#size-cells = <1>;
+			ranges = <0x0 0x0 0xe1000000 0x1000000 //Nand CS Region
+				  0x1 0x0 0xe2000000 0x2000000 //SRAM/NOR CS Region
+				  0x2 0x0 0xe4000000 0x2000000>; //SRAM/NOR CS Region
+			nand_0: flash@e1000000 {
+				compatible = "arm,pl353-nand-r2p1"
+				reg = <0 0 0x1000000>;
