+title: LPDDR channel with chip/rank topology description
+
+description:
+  An LPDDR channel is a completely independent set of LPDDR pins (DQ, CA, CS,
+  CK, etc.) that connect one or more LPDDR chips to a host system. The main
+  purpose of this node is to overall LPDDR topology of the system, including the
+  amount of individual LPDDR chips and the ranks per chip.

+      multiple instances of that type of chip are wired in parallel on this
+      channel (with the channel's DQ pins split up between the different
+      chips, and the CA, CS, etc. pins of the different chips all shorted
+      together).  This means that the total physical memory controlled by a
+      channel is equal to the sum of the densities of each rank on the

+      the io-width of the LPDDR chip.

+description:
+  Different LPDDR types generally use the same properties and only differ in the
+  range of legal values for each. This file defines the common parts that can be
+  reused for each type. Nodes using this schema should generally be nested under
+  an LPDDR channel node.
