Default value is the reset value of SOC

Default value: 16777215

response-timeout

int

Response timeout, as multiple of the SD clock. See RESPONSE_TIMEOUT field
of SDIF. Default value is the maximum possible timeout

DEBOUNCE_COUNT field of SDIF. Default value is the reset value of SOC.

Default value: 16777215

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

This property is required.

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

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.
