+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>;
+ (...)
+ };
+ nor0: flash@e2000000 {

v11 was sent long time ago and also reviewed by Linus here
https://lore.kernel.org/patchwork/patch/961603/
I can't see changelog which you have in v11. And also recorded changes
if any.
Then this driver will go through arm-soc tree via me.
Thanks,
Michal
