- arm,primecell-periphid : contains the PrimeCell Peripheral ID, it overrides
the ID provided by the HW
- resets : phandle to internal reset line.
+ Should be defined for sdmmc variant.
- vqmmc-supply : phandle to the regulator device tree node, mentioned
as the VCCQ/VDD_IO supply in the eMMC/SD specs.
+specific for ux500 variant:
- st,sig-dir-dat0 : bus signal direction pin used for DAT[0].
- st,sig-dir-dat2 : bus signal direction pin used for DAT[2].
- st,sig-dir-dat31 : bus signal direction pin used for DAT[3] and DAT[1].
- st,sig-dir-cmd : cmd signal direction pin used for CMD.
- st,sig-pin-fbclk : feedback clock signal pin used.
+specific for sdmmc variant:
+- st,sig-dir : signal direction polarity used for cmd, dat0 dat123.
+- st,neg-edge : data & command phase relation, generated on
+ sd clock falling edge.
+- st,use-ckin : use ckin pin from an external driver to sample
+ the receive data (example: with voltage
+ switch transceiver).

Deprecated properties:
- mmc-cap-mmc-highspeed : indicates whether MMC is high speed capable.
- mmc-cap-sd-highspeed : indicates whether SD is high speed capable.
