+description:
+  Multipd Peripheral Image Loader loads firmware and boots Q6 pd, WCSS pd
+  remoteproc's on the Qualcomm IPQ5018, IPQ9574 SoC. Pd means protection
+  domain. It's similar to process in Linux. Here QDSP6 processor runs each
+  wifi radio functionality on a separate process. One process can't access
+  other process resources, so this is termed as PD i.e protection domain.

+      In Multipd model, WCSS pd depends on Q6 pd i.e Q6 pd should be up before
+      WCSS. It can be achieved by keeping wcss pd node as subnode of Q6
+      device node.
