Subject: [PATCH v2 3/7] dt-bindings: remoteproc: qcom,pas: Document pas for
SoCCP on Kaanapali and Glymur platforms
Document the component used to boot SoCCP on Kaanapali SoC and add
compatible for Glymur SoCCP which could fallback to Kaanapali. Extend
the "qcom,smem-states" and "qcom,smem-state-names" properties and
add conditions for the "interrupts" and "interrupt-names" properties
in the pas-common.

+description:
+ The SoC Control Processor (SoCCP) is small RISC-V MCU that controls USB
+ Type-C, battery charging and various other functions on Qualcomm SoCs, somewhat
+ analogous to traditional PC Embedded Controllers. This document describes
+ the Peripheral Authentication Service loads and boots firmware for SoCCP.
