Subject: [PATCH v8 2/8] media: v4l: ctrls: add a control for enabling strobe output
Date: Tue, 04 Nov 2025 15:30:53 +0100 [thread overview]
Message-ID: <20251104-ov9282-flash-strobe-v8-2-b91dfef1c65a@linux.dev> (raw)
In-Reply-To: <20251104-ov9282-flash-strobe-v8-0-b91dfef1c65a@linux.dev>
Add a control V4L2_CID_FLASH_STROBE_OE to en- or disable the
strobe output of v4l2 devices (most likely sensors).
