[PATCH 3/4] media: qcom: camss: Add support for SM8150
From: Andrew Gigena via B4 Relay
Date: Wed Nov 04 2026 - 16:54:28 EST
From: Andrew Gigena <mail@xxxxxxxxxxxxxxxx>
Add CAMSS platform data for the Qualcomm SM8150 SoC. The camera
subsystem contains four CSIPHY, four CSID (two full and two lite), two
VFE and two VFE-Lite instances.
The hardware reuses the existing 3-phase 1.0 CSIPHY, Gen2 CSID and
VFE 17x implementations; the CSIPHY uses the SC8280XP lane register
layout. Add CAMSS_8150 to the version enum and to the shared code
paths, then add the per-block clock, regulator, power domain,
interrupt and interconnect resources.
