+Description:	MIPS VPE remoteproc start
+
+	This node only exists when a VPE is considered offline by Linux. Writes
+	to this file will start firmware running on a VPE.
+
+	If the VPE is idle, specifying a name will cause a remoteproc instance
+	to be allocated, which will cause the core to be stolen, the firmware
+	image to be loaded, and the remoteproc instance to be started.
+	Otherwise, the operation will fail.

+Description:	MIPS VPE remoteproc stop
+
+	This node only exists when a VPE is considered offline by Linux. Writes
+	to this file will stop firmware running on a VPE.
+
+	If the VPE is running a remote proc instance, the instance will be
+	stopped, the core returned, and the instance freed.
