Clock source to be used by the I2S peripheral for the master clock
(MCK) generator. The generator is only needed when the I2S peripheral
is operating in Master mode. The following options are available:
- "PCLK32M": 32 MHz peripheral clock, synchronous to HFCLK
- "PCLK32M_HFXO": PCLK32M running off the 32 MHz crystal oscillator
(HFXO) for better clock accuracy and jitter performance
- "ACLK": Audio PLL clock with configurable frequency (frequency for
this clock must be set via the "hfclkaudio-frequency" property
in the "nordic,nrf-clock" node); this clock source is only available
in the nRF53 Series SoCs and it requires the use of HFXO

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 “nordic,nrf-i2s” compatible.

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.
