Subject: [RFC PATCH 3/3] media: ti: j721e-csi2rx: Add support for VIDIOC_LOG_STATUS
Date: Wed, 12 Feb 2025 18:42:44 +0530 [thread overview]
Message-ID: <20250212131244.1397722-4-y-abhilashchandra@ti.com> (raw)
In-Reply-To: <20250212131244.1397722-1-y-abhilashchandra@ti.com>
The VIDIOC_LOG_STATUS ioctl outputs the current status of a device to the
kernel log. When this ioctl is called on a video device, the current
implementation queries the log status for all connected subdevices in the
media pipeline.
