+What:           /config/stp-policy
+Date:           June 2015
+KernelVersion:  4.3
+Description:
+                This group contains policies mandating Master/Channel allocation
+                for software sources wishing to send trace data over an STM
+                device.
+
+What:           /config/stp-policy/<device>.<policy>
+Date:           June 2015
+KernelVersion:  4.3
+Description:
+                This group is the root of a policy; its name is a concatenation
+                of an stm device name to which this policy applies and an
+                arbitrary string. If <device> part doesn't match an existing
+                stm device, mkdir will fail with ENODEV; if that device already
+                has a policy assigned to it, mkdir will fail with EBUSY.
+
+What:           /config/stp-policy/<device>.<policy>/device
+Date:           June 2015
+KernelVersion:  4.3
+Description:
+                STM device to which this policy applies, read only. Same as the
+                <device> component of its parent directory.
+
+What:           /config/stp-policy/<device>.<policy>/<node>
+Date:           June 2015
+KernelVersion:  4.3
+Description:
+                Policy node is a string identifier that software clients will
+                use to request a master/channel to be allocated and assigned to
+                them.
+
+What:           /config/stp-policy/<device>.<policy>/<node>/masters
+Date:           June 2015
+KernelVersion:  4.3
+Description:
+                Range of masters from which to allocate for users of this node.
+                Write two numbers: the first master and the last master number.
+
+What:           /config/stp-policy/<device>.<policy>/<node>/channels
+Date:           June 2015
+KernelVersion:  4.3
+Description:
+                Range of channels from which to allocate for users of this node.
+                Write two numbers: the first channel and the last channel
+                number.
