The OmniVision OG0VA1B is a 1/10-inch monochrome CMOS VGA image sensor. It outputs 10-bit raw (Y10) frames at up to 640x480 resolution over a single-lane MIPI CSI-2 interface and is controlled via an I2C-compatible SCCB bus. This driver has been verified(include tpg) on the Purwa EVK. Signed-off-by: Wenmeng Liu --- Changes in v7: - Drop the test pattern rename patch. As Sakari noted, a monochrome colour filter does not imply the internal TPG cannot generate colour patterns, so the original "Vertical Colour Bars" name is kept. -- Sakari - Give the control registers shared by both sensors (mode select, software reset, exposure, analogue gain, vertical timing and the test pattern enable bit) a common OG0V_ prefix; part-specific registers keep their per-sensor prefix. -- Sakari - Reorder struct og0ve1b_sensor_data members to avoid padding. -- Sakari - Link to v6: https://lore.kernel.org/r/20260901-og0va1b-v6-0-a05b2d04c892@oss.qualcomm.com Changes in v6: - Rebased onto v7.3-rc1 and added the Vladimir`s Reviewed-by tag for Patch 2. - Link to v5: https://lore.kernel.org/all/20260731-og0va1b-v5-0-c2b90b601241@oss.qualcomm.com/ Changes in v5: - Use div_u64() for pixel rate calculation to avoid 64-bit division helpers on 32-bit architectures. -- sashiko-bot, kernel test robot - Link to v4: https://lore.kernel.org/r/20260729-og0va1b-v4-0-ec7e7ed87b2b@oss.qualcomm.com Changes in v4: - Rename the OG0VA1B and OG0VE1B test pattern menu entries to make them more accurate. -- Vladimir - Link to v3: https://lore.kernel.org/r/20260708-og0va1b-v3-0-de8e44455a42@oss.qualcomm.com Changes in v3: - Generalise the binding title and description for both sensors. -- Vladimir - Keep the cached pre_isp read so the OG0VE1B test pattern still works, select it via a per-sensor callback. -- Bryan, Vladimir - Rename the "sensor" field to "data", drop bpp (derive from code) and add og0ve1b_pixel_rate(). -- Vladimir - Sort defines, rename the shared CHIP_ID reg to OG0V_ and order og0va1b_data first. -- Vladimir - Expose all four OG0VA1B test patterns instead of one. - Link to v2: https://lore.kernel.org/r/20260702-og0va1b-v2-0-0071442caa2a@oss.qualcomm.com Changes in v2: - Integrate OG0VA1B into the existing og0ve1b driver and binding instead. -- Vladimir - Link to v1: https://lore.kernel.org/r/20260618-og0va1b-v1-0-dda71bb83009@oss.qualcomm.com --- Wenmeng Liu (3): dt-bindings: media: i2c: og0ve1b: Add OmniVision OG0VA1B camera sensor media: i2c: og0ve1b: Introduce per-sensor data structure media: i2c: og0ve1b: Add support for OmniVision OG0VA1B .../bindings/media/i2c/ovti,og0ve1b.yaml | 15 +- drivers/media/i2c/og0ve1b.c | 452 +++++++++++++++++---- 2 files changed, 383 insertions(+), 84 deletions(-) --- base-commit: e5e04726cdd043e309677071ab1b65a4b18f422b change-id: 20260618-og0va1b-55bbf3cabb0e Best regards, -- Wenmeng Liu
