0001 * Fujitsu SDHCI controller
0002
0003 This file documents differences between the core properties in mmc.txt
0004 and the properties used by the sdhci_f_sdh30 driver.
0005
0006 Required properties:
0007 - compatible: "fujitsu,mb86s70-sdhci-3.0"
0008 - clocks: Must contain an entry for each entry in clock-names. It is a
0009 list of phandles and clock-specifier pairs.
0010 See ../clocks/clock-bindings.txt for details.
0011 - clock-names: Should contain the following two entries:
0012 "iface" - clock used for sdhci interface
0013 "core" - core clock for sdhci controller
0014
0015 Optional properties:
0016 - vqmmc-supply: phandle to the regulator device tree node, mentioned
0017 as the VCCQ/VDD_IO supply in the eMMC/SD specs.
0018 - fujitsu,cmd-dat-delay-select: boolean property indicating that this host
0019 requires the CMD_DAT_DELAY control to be enabled.

0021 Example:
0022
0023 sdhci1: mmc@36600000 {
0024 compatible = "fujitsu,mb86s70-sdhci-3.0";
0025 reg = <0 0x36600000 0x1000>;
0026 interrupts = <0 172 0x4>,
0027 <0 173 0x4>;
0028 bus-width = <4>;
0029 vqmmc-supply = <&vccq_sdhci1>;
0030 clocks = <&clock 2 2 0>, <&clock 2 3 0>;
0031 clock-names = "iface", "core";
0032 };
