* 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"; |
|
};
