+      Clock source to be used by the TDM peripheral. The following options
+      are available:
+      - "PCLK": Peripheral clock
+      - "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
+    enum:
+      - "PCLK"
+      - "ACLK"
