^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 466) white balance. The automatic adjustments can be paused independently
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 467) by setting the corresponding lock bit to 1. The camera then retains
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 468) the settings until the lock bit is cleared. The following lock bits
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 469) are defined:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 471) When a given algorithm is not enabled, drivers should ignore
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 472) requests to lock it and should return no error. An example might be

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 495) The unit is undefined. A positive value moves the camera to the

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 507) This read-only control describes the camera orientation by reporting its
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 508) mounting position on the device where the camera is installed. The control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 509) value is constant and not modifiable by software. This control is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 510) particularly meaningful for devices which have a well defined orientation,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 511) such as phones, laptops and portable devices since the control is expressed
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 512) as a position relative to the device's intended usage orientation. For
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 513) example, a camera installed on the user-facing side of a phone, a tablet or
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 514) a laptop device is said to be have ``V4L2_CAMERA_ORIENTATION_FRONT``

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 564) Assuming you can bring your laptop with you while swimming with sharks,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 565) the camera module of the laptop is installed on the user facing part of a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 566) laptop screen casing, and is typically used for video calls. The captured
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 567) images are meant to be displayed in landscape mode (width > height) on the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 568) laptop screen.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 569)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 570) The camera is typically mounted upside-down to compensate the lens optical

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 615) The camera sensor is typically mounted with its pixel array longer side
