1* Atmel SDHCI controller
2
3This file documents the differences between the core properties in
4Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the
5sdhci-of-at91 driver.
6
7Required properties:
8- compatible:		Must be "atmel,sama5d2-sdhci".
9- clocks:		Phandlers to the clocks.
10- clock-names:		Must be "hclock", "multclk", "baseclk";
11
12Optional properties:
13- microchip,sdcal-inverted: when present, polarity on the SDCAL SoC pin is
14  inverted. The default polarity for this signal is described in the datasheet.
15  For instance on SAMA5D2, the pin is usually tied to the GND with a resistor
16  and a capacitor (see "SDMMC I/O Calibration" chapter).

20sdmmc0: sdio-host@a0000000 {
21	compatible = "atmel,sama5d2-sdhci";
22	reg = <0xa0000000 0x300>;
23	interrupts = <31 IRQ_TYPE_LEVEL_HIGH 0>;
24	clocks = <&sdmmc0_hclk>, <&sdmmc0_gclk>, <&main>;
25	clock-names = "hclock", "multclk", "baseclk";
26};
