Subject: [PATCH v3 0/6] arm64: dts: qcom: qcs615: enable remoteprocs - ADSP
 and CDSP

Enable the remote processor PAS loader for QCS615 ADSP and CDSP
processors. This allows different platforms/architectures to control
(power on, load firmware, power off) those remote processors while
abstracting the hardware differences. Additionally, and add a PIL region
in IMEM so that post mortem debug tools can collect ramdumps.
