* Freescale Quad Serial Peripheral Interface(QuadSPI)
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : Should be "fsl,vf610-qspi"
|
||
|
|
- 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 "QuadSPI" and "QuadSPI-memory"
|
||
|
|
- interrupts : Should contain the interrupt for the device
|
||
|
|
- clocks : The clocks needed by the QuadSPI controller
|
||
|
|
- clock-names : the name of the clocks
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- fsl,qspi-has-second-chip: The controller has two buses, bus A and bus B.
|
||
|
|
Each bus can be connected with two NOR flashes.
|
||
|
|
Most of the time, each bus only has one NOR flash
|
||
|
|
connected, this is the default case.
|
||
|
|
But if there are two NOR flashes connected to the
|
||
|
|
bus, you should enable this property.
|
||
|
|
(Please check the board's schematic.)
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
qspi0: quadspi@40044000 {
|
||
|
|
compatible = "fsl,vf610-qspi";
|
||
|
|
reg = <0x40044000 0x1000>, <0x20000000 0x10000000>;
|
||
|
|
reg-names = "QuadSPI", "QuadSPI-memory";
|
||
|
|
interrupts = <0 24 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
|
clocks = <&clks VF610_CLK_QSPI0_EN>,
|
||
|
|
<&clks VF610_CLK_QSPI0>;
|
||
|
|
clock-names = "qspi_en", "qspi";
|
||
|
|
|
||
|
|
flash0: s25fl128s@0 {
|
||
|
|
....
|

|

};

};
