Kernel-3.10.0-957.el7_sdhci-fujitsu

• Fujitsu SDHCI controller

This file documents differences between the core properties in mmc.txt
and the properties used by the sdhci_f_sdh30 driver.

Required properties:

• compatible: “fujitsu,mb86s70-sdhci-3.0”
• clocks: Must contain an entry for each entry in clock-names. It is a
  list of phandles and clock-specifier pairs.
  See ../clocks/clock-bindings.txt for details.
• clock-names: Should contain the following two entries:
  “iface” - clock used for sdhci interface
  “core” - core clock for sdhci controller

Optional properties:

• vqmmc-supply: phandle to the regulator device tree node, mentioned
  as the VCCQ/VDD_IO supply in the eMMC/SD specs.

Example:

sdhci1: mmc@36600000 {
    compatible = "fujitsu,mb86s70-sdhci-3.0";
    reg = <0 0x36600000 0x1000>;
    interrupts = <0 172 0x4>,
             <0 173 0x4>;
    bus-width = <4>;
    vqmmc-supply = <&vccq_sdhci1>;
    clocks = <&clock 2 2 0>, <&clock 2 3 0>;
    clock-names = "iface", "core";
};
