[PATCH v2 3/7] dt-bindings: remoteproc: qcom,pas: Document pas for SoCCP on Kaanapali and Glymur platforms

Jingyi Wang
2025-10-29T08:05:51Z

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.
