Set the EPIT prescaler between 0 and 4095
This property is required. |
|
|
Set the RDC permission for specified peripheral: Resource Domain Controller (RDC)
supports flexible configuration on IP’s access permission, each individual IP can,
for example, be configured as A-core only or M-core only. This property uses some
macros defined in 'include/zephyr/dt-bindings/rdc/imx_rdc.h' to configure current
peripheral's access permission.
For example to allow both A53 and M7 Core to have read/write permission to current
peripheral:
rdc = <(RDC_DOMAIN_PERM(A53_DOMAIN_ID, RDC_DOMAIN_PERM_RW)|\
RDC_DOMAIN_PERM(M7_DOMAIN_ID, RDC_DOMAIN_PERM_RW))>;

Deprecated properties not inherited from the base binding file.
(None)
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,imx-epit” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
