-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 {
- compatible = "cfi-flash";
- reg = <1 0 0x2000000>;
- };
- nor1: flash@e4000000 {
- compatible = "cfi-flash";
- reg = <2 0 0x2000000>;
- };
- };
