+What: 		/sys/kernel/config/most_<component>
+Date: 		March 8, 2019
+KernelVersion:  5.2
+Description: 	Interface is used to configure and connect device channels
+		to component drivers.
+
+		Attributes are visible only when configfs is mounted. To mount
+		configfs in /sys/kernel/config directory use:
+		# mount -t configfs none /sys/kernel/config/

+Description:
+		The attributes:
+
+		buffer_size
+				configure the buffer size for this channel
+
+		subbuffer_size
+				configure the sub-buffer size for this channel
+				(needed for synchronous and isochronous data)
+
+
+		num_buffers
+				configure number of buffers used for this
+				channel
+
+		datatype
+				configure type of data that will travel over
+				this channel
+
+		direction
+				configure whether this link will be an input
+				or output
+
+		dbr_size
+				configure DBR data buffer size (this is used
+				for MediaLB communication only)
+
+		packets_per_xact
+				configure the number of packets that will be
+				collected from the network before being
+				transmitted via USB (this is used for USB
+				communication only)
+
+		device
+				name of the device the link is to be attached to
+
+		channel
+				name of the channel the link is to be attached to
+
+		comp_params
+				pass parameters needed by some components
+
+		create_link
+				write '1' to this attribute to trigger the
+				creation of the link. In case of speculative
+				configuration, the creation is post-poned until
+				a physical device is being attached to the bus.
+
+		destroy_link
+				write '1' to this attribute to destroy an
+				active link
