1 * Atmel SDHCI controller
3 This file documents the differences between the core properties in
4 Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the
8 - compatible: Must be "atmel,sama5d2-sdhci" or "microchip,sam9x60-sdhci".
9 - clocks: Phandlers to the clocks.
10 - clock-names: Must be "hclock", "multclk", "baseclk" for
11 "atmel,sama5d2-sdhci".
12 Must be "hclock", "multclk" for "microchip,sam9x60-sdhci".
15 - assigned-clocks: The same with "multclk".
16 - assigned-clock-rates The rate of "multclk" in order to not rely on the
17 gck configuration set by previous components.
18 - microchip,sdcal-inverted: when present, polarity on the SDCAL SoC pin is
19 inverted. The default polarity for this signal is described in the datasheet.
20 For instance on SAMA5D2, the pin is usually tied to the GND with a resistor
21 and a capacitor (see "SDMMC I/O Calibration" chapter).
