* 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";
|
};
