  • Wondermedia WM8505/WM8650 SD/MMC Host Controller

This file documents differences between the core properties described
by mmc.txt and the properties used by the wmt-sdmmc driver.

Required properties:

  • compatible: Should be “wm,wm8505-sdhc”.
  • interrupts: Two interrupts are required - regular irq and dma irq.

Optional properties:

  • sdon-inverted: SD_ON bit is inverted on the controller

Examples:

sdhc@d800a000 {
compatible = “wm,wm8505-sdhc”;
reg = <0xd800a000 0x1000>;
interrupts = <20 21>;
clocks = <&sdhc>;
bus-width = <4>;
sdon-inverted;
};
