  1. MPC83xx SPISEL_BOOT gpio controller
  2. Provide access to MPC83xx SPISEL_BOOT signal as a gpio to allow it to be
  3. easily bound as a SPI controller chip select.
  4. The SPISEL_BOOT signal is always an output.
  5. Required properties:
  6. - compatible: must be "fsl,mpc83xx-spisel-boot" or "fsl,mpc8309-spisel-boot".
  7. - reg: must point to the SPI_CS register in the SoC register map.
  8. - ngpios: number of gpios provided by driver, normally 1.
  9. Example:
  10. spisel_boot: spisel_boot@14c {
  11. compatible = "fsl,mpc8309-spisel-boot";
  12. reg = <0x14c 0x04>;
  13. #gpio-cells = <2>;
  14. device_type = "gpio";
  15. ngpios = <1>;
  16. };
