fsl,imx27-pwm
Vendor: Freescale Semiconductor
Description
This driver supports both i.MX6SX and i.MX7D PWM.
The compatible string is named "imx27" because the hardware module is the
same module present starting from imx27 CPUs and this driver can potentially
support other CPUs with imx27 module. This is also the same string used
in the Linux kernel.

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.
