Subject: [PATCH V3 0/5] Enable ADSP and CDSP for Glymur SoC

From: Sibi Sankar <quic_sibis@...cinc.com>

Qualcomm Glymur SoC variants predominantly boot Linux at EL2. This means
that the firmware streams of the remote processors are managed in kernel
and not in Gunyah hypervisor. Given that the Peripheral Image Loader for
Qualcomm SoCs now support running Linux Host at EL2 [1], this series
documents and enables ADSP and CDSP on Qualcomm Glymur SoCs with its
fastrpc nodes. A few variants of the SoC are expected to run Linux at EL1
hence the iommus properties are left optional.

Changes in v3:
- A few variants of the SoC are expected to run Linux at EL1 hence the
  iommus properties are left optional.
- Add fastrpc bindings and nodes.
- Link to v2: https://lore.kernel.org/all/20251029-knp-remoteproc-v2-0-6c81993b52ea@oss.qualcomm.com/

Changes in v2:
- Combined into Kaanapali series since they are fully compatible.
- Link to v1: https://lore.kernel.org/all/20250924183726.509202-1-sibi.sankar@oss.qualcomm.com/
