Subject: [PATCH 05/11] media: i2c: st-vd55g1: Default to illuminator on GPIO 1
Date: Fri, 18 Sep 2026 18:16:59 -0400 [thread overview]
Message-ID: <20260918221705.323510-6-pm@petermarshall.ca> (raw)
In-Reply-To: <20260918221705.323510-1-pm@petermarshall.ca>
Sensors enumerated through a bus at runtime instead of a device tree may
not have any GPIO pins detected. Assume the illuminator is connected to
GPIO 1.
