Max drive current in mA at 3.3V. A value of zero indicates no maximum
is specified by the driver.
|
|
|
Max drive current in mA at 3.0V. A value of zero indicates no maximum
is specified by the driver.
|
|
|
Max drive current in mA at 1.8V. A value of zero indicates no maximum
is specified by the driver.
|
|
|
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: |
|
|
Minimum bus frequency for SD card. This should be the frequency that
cards first will select when attached to the SDHC bus
Default value: |
|
|
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: |
|
|
The host controller supports HS200 at 1.8V

|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device
