Required properties:
- spi-max-frequency : maximum frequency for this device (Hz).
-- voltage-ranges : two cells are required, first cell specifies minimum
- slot voltage (mV), second cell specifies maximum slot voltage (mV).
- Several ranges could be specified.
Optional properties:
+- voltage-ranges : two cells are required, first cell specifies minimum
+ slot voltage (mV), second cell specifies maximum slot voltage (mV).
+ Several ranges could be specified. If not provided, 3.2v..3.4v is assumed.
- gpios : may specify GPIOs in this order: Card-Detect GPIO,
Write-Protect GPIO. Note that this does not follow the
binding from mmc.txt, for historical reasons.
