media: i2c: og01a1b: Specify monochrome media bus format instead of Bayer

2025-11-13T20:37:17Z

[ Upstream commit bfbd5aa5347fbd11ade188b316b800bfb27d9e22 ] The OmniVision OG01A1B image sensor is a monochrome sensor, it supports 8-bit and 10-bit RAW output formats only. That said the planar greyscale Y8/Y10 media formats are more appropriate for the sensor instead of the originally and arbitrary selected SGRBG one, since there is no red, green or blue color components.

media: adv7180: Only validate format in querystd

2025-11-13T20:37:13Z

[ Upstream commit 91c5d7c849273d14bc4bae1b92666bdb5409294a ] The .querystd callback should not program the device with the detected standard, it should only report the standard to user-space. User-space may then use .s_std to set the standard, if it wants to use it. All that is required of .querystd is to setup the auto detection of standards and report its findings. While at it add some documentation on why this can't happen while streaming and improve the error handling using a scoped guard.

media: adv7180: Do not write format to device in set_fmt

2025-11-13T20:37:13Z

[ Upstream commit 46c1e7814d1c3310ef23c01ed1a582ef0c8ab1d2 ] The .set_fmt callback should not write the new format directly do the device, it should only store it and have it applied by .s_stream. The .s_stream callback already calls adv7180_set_field_mode() so it's safe to remove programming of the device and just store the format and have .s_stream apply it.

media: i2c: mt9v111: fix incorrect type for ret

2025-10-19T14:37:20Z

commit bacd713145443dce7764bb2967d30832a95e5ec8 upstream. Change "ret" from unsigned int to int type in mt9v111_calc_frame_rate() to store negative error codes or zero returned by __mt9v111_hw_reset() and other functions. Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but it's ugly as pants. No effect on runtime.

media: i2c: mt9p031: fix mbus code initialization

2025-10-19T14:37:20Z

commit 075710b670d96cf9edca1894abecba7402fe4f34 upstream. The mediabus code is device dependent, but the probe() function thought that device_get_match_data() would return the code directly, when in fact it returned a pointer to a struct mt9p031_model_info. As a result, the initial mbus code was garbage. Tested with a BeagleBoard xM and a Leopard Imaging LI-5M03 sensor board.
