Subject: [RCF 2/2] media: verisilicon: Use V4L2_FMT_FLAG_ALL_FORMATS flag
Date: Thu, 11 Jan 2024 17:07:21 +0100	[thread overview]
Message-ID: <20240111160721.50020-3-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20240111160721.50020-1-benjamin.gaignard@collabora.com>

If V4L2_FMT_FLAG_ALL_FORMATS flag has been set when calling
VIDIOC_ENUM_FMT ignore depth match and returns all the
hardware supported pixels formats.
