Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
This property is **required**.
* - ``pinctrl-names``

Names for the provided states. The number of names needs to match the
number of states.
This property is **required**.
* - ``max-current-330``

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``

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``
- .. code-block:: none
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

- .. code-block:: none
The host controller supports HS200 at 1.8V
* - ``mmc-hs400-1_8v``
- ``boolean``
- .. code-block:: none
The host controller supports HS400 at 1.8V
* - ``pinctrl-1``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the second state. See pinctrl-0.
* - ``pinctrl-2``

- .. code-block:: none
Pin configuration/s for the fourth state. See pinctrl-0.
* - ``pinctrl-4``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the fifth state. See pinctrl-0.
.. group-tab:: Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
.. group-tab:: Base properties
Properties inherited from the base binding file, which defines
common properties that may be set on many nodes. Not all of these
may apply to the "nxp,lpc-sdif" compatible.
