^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) This file documents differences between the core properties described
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) by mmc.txt and the properties used by the mmc_spi driver.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) - spi-max-frequency : maximum frequency for this device (Hz).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) - voltage-ranges : two cells are required, first cell specifies minimum
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9)   slot voltage (mV), second cell specifies maximum slot voltage (mV).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)   Several ranges could be specified.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - gpios : may specify GPIOs in this order: Card-Detect GPIO,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)   Write-Protect GPIO. Note that this does not follow the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)   binding from mmc.txt, for historical reasons.
