Subject: [PATCH 0/7] media: i2c: st-vd55g1: Genericize driver and add VD55G0 support
Date: Wed, 2 Sep 2026 16:45:39 -0400 [thread overview]
Message-ID: <20260902204549.657228-1-pm@petermarshall.ca> (raw)
This patch series refactors the STMicroelectronics VD55G1 and VD65G4 image
sensor driver (vd55g1) into a generic VD55G family driver (vd55g) and adds
support for the VD55G0 monochrome sensor.
The VD55G0 sensor is found in devices such as the Microsoft Surface Pro 9 under
ACPI HID `SMO55F0`. It features a native resolution of 644 x 604 pixels and
differs from later variants in the family in several ways:
* It uses a different native resolution and register addresses mapping,
requiring specification of generational feature differences.
* It lacks support for spatial and temporal HDR.
* It requires an exposure duty cycle limit to keep the illuminator current safe.
Tested on a Microsoft Surface Pro 9 (an Intel IPU6 platform with ACPI
HID "SMO55F0") running libcamera.
