nxp,s32-emios
Vendor: NXP Semiconductors
Description
NXP S32 Enhanced Modular IO SubSystem (eMIOS) node for S32 SoCs.
eMIOS provides independent unified channels (UCs), some of channels
have internal counter that either can be used independently or used
as a reference timebase (master bus) for other channels.

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

This property is required. See Important properties for more information. |
|
|
register space
This property is required. See Important properties for more information. |
|
|
name of each register space
|

|
extended interrupt specifier for device
|
|
|
name of each interrupt
This property is required. |
|
|
phandle to interrupt controller node
|
|
|
Human readable string describing the device (used as device_get_binding() argument)
See Important properties for more information. This property is deprecated. |

|
Channel identifier for the master bus.
This property is required. |
|
|
A channel mask for channels that by hardware design can use this master bus
as timebase for the operation, lsb is channel 0. The mask bit for this master bus
must always 0 because a master bus should not do other thing than a base timer.
This property is required. |
|
|
Clock divider value for internal UC prescaler.
Clock for internal counter = (eMIOS clock / global prescaler) / internal prescaler.
This property is required. Legal values: |
|
|
Master bus type.
This property is required. Legal values: |
|
|
Master bus mode.
This property is required. Legal values: |
|
|
Default period (in ticks) for master bus at boot time. This determines PWM period
for channels use this bus as reference timebase. Could be in range [2 ... 65535]
This property is required. |
|
|
Freeze internal counter when the chip enters Debug mode.
