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"; }; |
