-* Atmel SDHCI controller
-
-This file documents the differences between the core properties in
-Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the
-sdhci-of-at91 driver.
-
-Required properties:
-- compatible: Must be "atmel,sama5d2-sdhci" or "microchip,sam9x60-sdhci"
- or "microchip,sam9x7-sdhci", "microchip,sam9x60-sdhci".
-- clocks: Phandlers to the clocks.
-- clock-names: Must be "hclock", "multclk", "baseclk" for
- "atmel,sama5d2-sdhci".
- Must be "hclock", "multclk" for "microchip,sam9x60-sdhci".
- Must be "hclock", "multclk" for "microchip,sam9x7-sdhci".
-
-Optional properties:
-- assigned-clocks: The same with "multclk".
-- assigned-clock-rates The rate of "multclk" in order to not rely on the
- gck configuration set by previous components.
-- microchip,sdcal-inverted: when present, polarity on the SDCAL SoC pin is
- inverted. The default polarity for this signal is described in the datasheet.
- For instance on SAMA5D2, the pin is usually tied to the GND with a resistor
- and a capacitor (see "SDMMC I/O Calibration" chapter).
-
-Example:
-
-mmc0: sdio-host@a0000000 {
- compatible = "atmel,sama5d2-sdhci";
- reg = <0xa0000000 0x300>;
- interrupts = <31 IRQ_TYPE_LEVEL_HIGH 0>;
- clocks = <&sdmmc0_hclk>, <&sdmmc0_gclk>, <&main>;
- clock-names = "hclock", "multclk", "baseclk";
- assigned-clocks = <&sdmmc0_gclk>;
- assigned-clock-rates = <480000000>;
-};
