+- qcom,fifo-empty-threshold:
+  Usage:	optional
+  Value type:	<u32>
+  Definition:	Specifies the FIFO empty threshold. The "fifo-empty" IRQ will be

 - qcom,use-erm:
   Usage:	optional
   Value type:	<bool>
   Definition:	Specifies if the hardware is driving an ERM actuator. If it's

+- nvmem-cell-names:
+  Usage:	optional
+  Value type:	<string>
+  Definition:	The nvmem cell name of the SDAM module where the closed-loop
