MPC83xx SPISEL_BOOT gpio controller
|
||
|
|
|
||
|
|
Provide access to MPC83xx SPISEL_BOOT signal as a gpio to allow it to be
|
||
|
|
easily bound as a SPI controller chip select.
|
||
|
|
|
||
|
|
The SPISEL_BOOT signal is always an output.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible: must be "fsl,mpc83xx-spisel-boot" or "fsl,mpc8309-spisel-boot".
|
||
|
|
- reg: must point to the SPI_CS register in the SoC register map.
|
||
|
|
- ngpios: number of gpios provided by driver, normally 1.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
spisel_boot: spisel_boot@14c {
|
||
|
|
compatible = "fsl,mpc8309-spisel-boot";
|
||
|
|
reg = <0x14c 0x04>;
|
||
|
|
#gpio-cells = <2>;
|
||
|
|
device_type = "gpio";
|
||
|
|
ngpios = <1>;
|
||
|
|
};
