Details |
|---|---|---|
|
|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
This property is required. |
|
|
Names for the provided states. The number of names needs to match the
number of states.
This property is required. |
|
|
Mapping table between Wake-Up Input (WUI) and ESPI_RST signal.
For example the WUI mapping on NPCX7 would be
espi-rst-wui = <&wui_cr_sin1>;
This property is required. |
|
|
The maximum receive channel payload size.
This property is required. |
|
|
The maximum transmit channel payload size.
This property is required. |
|
|
Array of encoded virtual wire information
Update the vw index in group setting. Here is the format.
< ESPI_NPCX_VW_EX_VAL(direction, group_number, index) >
direction: 1 for ESPI_CONTROLLER_TO_TARGET and 0 for ESPI_TARGET_TO_CONTROLLER.
group_number: The number of VWEVMS or VWEVSM.
index: The index to be replaced.
For example, update the index of VWEVMS6 into 0x4A and the index of VWEVSM8 into 0x53
vw-index-extend-set = < ESPI_NPCX_VW_EX_VAL(1, 6, 0x4A)
ESPI_NPCX_VW_EX_VAL(0, 8, 0x53) >

|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
