+title: NXP SPI Flash Interface (SPIFI)
+
+description:
+ NXP SPIFI is a specialized SPI interface for serial Flash devices.
+ It supports one Flash device with 1-, 2- and 4-bits width in SPI
+ mode 0 or 3. The controller operates in either command or memory
+ mode. In memory mode the Flash is accessible from the CPU as
+ normal memory.

-* NXP SPI Flash Interface (SPIFI)
-
-NXP SPIFI is a specialized SPI interface for serial Flash devices.
-It supports one Flash device with 1-, 2- and 4-bits width in SPI
-mode 0 or 3. The controller operates in either command or memory
-mode. In memory mode the Flash is accessible from the CPU as
-normal memory.
-
-Required properties:
- - compatible : Should be "nxp,lpc1773-spifi"
- - reg : the first contains the register location and length,
- the second contains the memory mapping address and length
- - reg-names: Should contain the reg names "spifi" and "flash"
- - interrupts : Should contain the interrupt for the device
- - clocks : The clocks needed by the SPIFI controller
- - clock-names : Should contain the clock names "spifi" and "reg"
-
-Optional properties:
- - resets : phandle + reset specifier
-
-The SPI Flash must be a child of the SPIFI node and must have a
-compatible property as specified in bindings/mtd/jedec,spi-nor.txt
-
-Optionally it can also contain the following properties.
- - spi-cpol : Controller only supports mode 0 and 3 so either
- both spi-cpol and spi-cpha should be present or
- none of them
- - spi-cpha : See above
- - spi-rx-bus-width : Used to select how many pins that are used
- for input on the controller
-
-See bindings/spi/spi-bus.txt for more information.
-
-Example:
-spifi: spifi@...03000 {
- compatible = "nxp,lpc1773-spifi";
- reg = <0x40003000 0x1000>, <0x14000000 0x4000000>;
- reg-names = "spifi", "flash";
- interrupts = <30>;
- clocks = <&ccu1 CLK_SPIFI>, <&ccu1 CLK_CPU_SPIFI>;
- clock-names = "spifi", "reg";
- resets = <&rgu 53>;
-
- flash@0 {
- compatible = "jedec,spi-nor";
- spi-cpol;
- spi-cpha;
- spi-rx-bus-width = <4>;
- #address-cells = <1>;
- #size-cells = <1>;
-
- partition@0 {
- label = "data";
- reg = <0 0x200000>;
- };
- };
-};
