1 | * Fujitsu SDHCI controller |
2 | ||
3 | This file documents differences between the core properties in mmc.txt | |
4 | and the properties used by the sdhci_f_sdh30 driver. | |
5 | ||
6 | Required properties: | |
7 | - compatible: "fujitsu,mb86s70-sdhci-3.0" | |
8 | - clocks: Must contain an entry for each entry in clock-names. It is a | |
9 | list of phandles and clock-specifier pairs. | |
10 | See ../clocks/clock-bindings.txt for details. | |
11 | - clock-names: Should contain the following two entries: | |
12 | "iface" - clock used for sdhci interface | |
13 | "core" - core clock for sdhci controller | |
14 | ||
15 | Optional properties: | |
16 | - vqmmc-supply: phandle to the regulator device tree node, mentioned | |
17 | as the VCCQ/VDD_IO supply in the eMMC/SD specs. | |
18 | ||
19 | Example: | |
20 | ||
21 | sdhci1: mmc@36600000 { | |
22 | compatible = "fujitsu,mb86s70-sdhci-3.0"; | |
23 | reg = <0 0x36600000 0x1000>; | |
24 | interrupts = <0 172 0x4>, | |
25 | <0 173 0x4>; | |
26 | bus-width = <4>; | |
27 | vqmmc-supply = <&vccq_sdhci1>; | |
28 | clocks = <&clock 2 2 0>, <&clock 2 3 0>; | |
29 | clock-names = "iface", "core"; | |
30 | }; |
