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).
8 - voltage-ranges : two cells are required, first cell specifies minimum
9 slot voltage (mV), second cell specifies maximum slot voltage (mV).
10 Several ranges could be specified.
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.
16 - interrupt-parent : the phandle for the interrupt controller that
17 services interrupts for this device.
