  1. * Freescale MXS MMC controller
  2. The Freescale MXS Synchronous Serial Ports (SSP) can act as a MMC controller
  3. to support MMC, SD, and SDIO types of memory cards.
  4. Required properties:
  5. - compatible: Should be "fsl,<chip>-mmc". The supported chips include
  6. imx23 and imx28.
  7. - reg: Should contain registers location and length
  8. - interrupts: Should contain ERROR and DMA interrupts
  9. - fsl,ssp-dma-channel: APBH DMA channel for the SSP
  10. - bus-width: Number of data lines, can be <1>, <4>, or <8>
  11. Optional properties:
  12. - wp-gpios: Specify GPIOs for write protection
  13. Examples:
  14. ssp0: ssp@80010000 {
  15. compatible = "fsl,imx28-mmc";
  16. reg = <0x80010000 2000>;
  17. interrupts = <96 82>;
  18. fsl,ssp-dma-channel = <0>;
  19. bus-width = <8>;
  20. };
