Subject: [PATCH v3 00/11] Remoteprocs (ADSP, CDSP, WPSS) for SC7280

This series adds support for the ADSP, CDSP and WPSS remoteprocs found
on SC7280. And finally enable them and WiFi on the QCM6490-based
Fairphone 5 smartphone.

The first two patches are fixes for the MPSS to fix some dt validation
issues. They're included in this series to avoid conflicts with the
later patches and keep it simpler.

Then there's two patches reorganizing the reserved-memory setup for
sc7280 in preparations for the new remoteprocs.

Please note, that the ChromeOS-based devices using SC7280 need different
driver and dts support, similar to how there's already
qcom,sc7280-mpss-pas for "standard" firmware and there's
qcom,sc7280-mss-pil for ChromeOS firmware.

I'm aware of the series also adding SC7280 ADSP support with the last
revision sent in June this year.

https://lore.kernel.org/linux-arm-msm/20230616103534.4031331-1-quic_mohs@quicinc.com/

However there's some differences since that series added the "pil"
variant for ChromeOS, not "pas" for standard firmware. Also it seems on
ChromeOS devices gpr+q6apm+q6prm is used. On my device it appears to be
instead apr+q6afe+q6asm+q6adm but I don't add either in this series to
keep it a bit simpler, and I couldn't test much of that yet.
