[PATCH v2 01/24] dt-bindings: qcom,pdc: Fix OS DRV reg size in example
From: Mukesh Ojha
Date: Wed May 27 2026 - 05:45:49 EST
PDC instances have multiple 0x10000-byte DRV regions, with each region
serving a specific client like HLOS (High level operating system),
TrustZone, Hypervisor etc.,. The OS-visible PDC instance should uses its
own DRV region, while other DRV regions belong to other clients.
Update the binding example to describe a single OS DRV region by
changing the reg size from 0x30000 to 0x10000. This matches the example
with the OS-facing PDC nodes used on Qualcomm platforms and avoids
suggesting that the example should span multiple client regions.
