-* Aspeed Firmware Memory controller
-* Aspeed SPI Flash Memory Controller
-
-The Firmware Memory Controller in the Aspeed AST2500 SoC supports
-three chip selects, two of which are always of SPI type and the third
-can be SPI or NOR type flash. These bindings only describe SPI.
-
-The two SPI flash memory controllers in the AST2500 each support two
-chip selects.
-
-Required properties:
- - compatible : Should be one of
- "aspeed,ast2400-fmc" for the AST2400 Firmware Memory Controller
- "aspeed,ast2400-spi" for the AST2400 SPI Flash memory Controller
- "aspeed,ast2500-fmc" for the AST2500 Firmware Memory Controller
- "aspeed,ast2500-spi" for the AST2500 SPI flash memory controllers
-
- - reg : the first contains the control register location and length,
- the second contains the memory window mapping address and length
- - #address-cells : must be 1 corresponding to chip select child binding
- - #size-cells : must be 0 corresponding to chip select child binding
-
-Optional properties:
- - interrupts : Should contain the interrupt for the dma device if an
- FMC
-
-The child nodes are the SPI flash modules which must have a compatible
-property as specified in bindings/mtd/jedec,spi-nor.txt
-
-Optionally, the child node can contain properties for SPI mode (may be
-ignored):
- - spi-max-frequency - max frequency of spi bus
-
-
-Example:
-fmc: fmc@1e620000 {
- compatible = "aspeed,ast2500-fmc";
- reg = < 0x1e620000 0x94
- 0x20000000 0x02000000 >;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupts = <19>;
- flash@0 {
- reg = < 0 >;
- compatible = "jedec,spi-nor";
- /* spi-max-frequency = <>; */
- /* m25p,fast-read; */
- #address-cells = <1>;
- #size-cells = <1>;
- };
-};
