Subject: [PATCH V2 01/13] dt-bindings: remoteproc: qcom: Add support for multipd model
Add new binding document for multipd model remoteproc.
IPQ5018, IPQ9574 follows multipd model.
Signed-off-by: Manikanta Mylavarapu <quic_mmanikan@...cinc.com>

Changes in V2:
- Fixed all comments and rebased for TOT.
- Changed to BSD-3-Clause based on internal open source team
suggestion.
- Added firmware-name.

+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.
