* SOCIONEXT Milbeaut SDHCI controller
|
|
|
|
This file documents differences between the core properties in mmc.txt
|
|
and the properties used by the sdhci_milbeaut driver.
|
|
|
|
Required properties:
|
|
- compatible: "socionext,milbeaut-m10v-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:
|
|
- fujitsu,cmd-dat-delay-select: boolean property indicating that this host
|
|
requires the CMD_DAT_DELAY control to be enabled.
|
|
|
|
Example:
|
|
sdhci3: mmc@1b010000 {
|
|
compatible = "socionext,milbeaut-m10v-sdhci-3.0";
|
|
reg = <0x1b010000 0x10000>;
|
|
interrupts = <0 265 0x4>;
|
|
voltage-ranges = <3300 3300>;
|
|
bus-width = <4>;
|
|
clocks = <&clk 7>, <&ahb_clk>;
|
|
clock-names = "core", "iface";
|
|
cap-sdio-irq;
|
|
fujitsu,cmd-dat-delay-select;
|
|
};
