Properties

Properties not inherited from the base binding file.

Name

Type

Details

max-current-330

int

Max drive current in mA at 3.3V. A value of zero indicates no maximum
is specified by the driver.

max-current-300

int

Max drive current in mA at 3.0V. A value of zero indicates no maximum
is specified by the driver.

max-current-180

int

Max drive current in mA at 1.8V. A value of zero indicates no maximum
is specified by the driver.

max-bus-freq

int

Maximum bus frequency for SD card. This should be the highest frequency
the SDHC is capable of negotiating with cards on the bus.

Default value: 400000

min-bus-freq

int

Minimum bus frequency for SD card. This should be the frequency that
cards first will select when attached to the SDHC bus

Default value: 400000

power-delay-ms

int

time in ms for SDHC to delay when toggling power to the SD card. This
delay gives the card time to power up or down fully

Default value: 500

mmc-hs200-1_8v

boolean

The host controller supports HS200 at 1.8V

mmc-hs400-1_8v

boolean

The host controller supports HS400 at 1.8V
