1 MMC/SD/SDIO slot directly connected to a SPI bus
3 This file documents differences between the core properties described
4 by mmc.txt and the properties used by the mmc_spi driver.
7 - spi-max-frequency : maximum frequency for this device (Hz).
10 - voltage-ranges : two cells are required, first cell specifies minimum
11 slot voltage (mV), second cell specifies maximum slot voltage (mV).
12 Several ranges could be specified. If not provided, 3.2v..3.4v is assumed.
13 - gpios : may specify GPIOs in this order: Card-Detect GPIO,
14 Write-Protect GPIO. Note that this does not follow the
15 binding from mmc.txt, for historical reasons.
