Hi, this patchset introduces cropping support for the Sony IMX274 sensor using the SELECTION API. Changes since v5 are only minor fixes and cleanups. Patch 1 introduces a helper to greatly simplify the code to write a multibyte register. Patch 2 implements the set_selection pad operation for cropping (V4L2_SEL_TGT_CROP) and binning (V4L2_SEL_TGT_COMPOSE). Usage examples: * Capture the entire 4K area, downscaled to 1080p with 2:1 binning: media-ctl -V '"IMX274":0[crop:(0,0)/3840x2160]' media-ctl -V '"IMX274":0[compose:(0,0)/1920x1080]' * Capture the central 1080p area (no binning): media-ctl -V '"IMX274":0[crop:(960,540)/1920x1080]' (this also sets the compose and fmt rects to 1920x1080) Regards, Luca Luca Ceresoli (2): media: imx274: use regmap_bulk_write to write multybyte registers media: imx274: add cropping support via SELECTION API drivers/media/i2c/imx274.c | 566 +++++++++++++++++++++++++++---------- 1 file changed, 412 insertions(+), 154 deletions(-) -- 2.17.1
