-* 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.
-- fujitsu,cmd-dat-delay-select: boolean property indicating that this host
- requires the CMD_DAT_DELAY control to be enabled.
-
-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";
- };
