Subject: [PATCH v6 04/11] media: v4l: ctrls: add a control for enabling hw strobe signal
Date: Wed, 16 Jul 2025 11:06:54 +0200	[thread overview]
Message-ID: <20250716-ov9282-flash-strobe-v6-4-934f12aeff33@linux.dev> (raw)
In-Reply-To: <20250716-ov9282-flash-strobe-v6-0-934f12aeff33@linux.dev>

Add a control V4L2_CID_FLASH_HW_STROBE_SIGNAL to en- or disable the
strobe output of v4l2 devices (most likely sensors).
