When only the image sizes gets changed, the format do not get updated causing the sensor to always report the one that was previously in use. Without this patch, updating frame size only fails: [fmt:UYVY8_2X8/640x480@1/30 field:none colorspace:srgb xfer:srgb ...] With this patch applied: [fmt:UYVY8_2X8/1024x768@1/30 field:none colorspace:srgb xfer:srgb ...] Fixes: 6949d864776e ("media: ov5640: do not change mode if format or frame interval is unchanged") Signed-off-by: Jacopo Mondi Signed-off-by: Maxime Ripard Tested-by: Adam Ford #imx6 w/ CSI2 interface on 4.19.6 and 4.20-RC5 Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/i2c/ov5640.c b/drivers/media/i2c/ov5640.c index a91d917..807bd0e 100644 --- a/drivers/media/i2c/ov5640.c +++ b/drivers/media/i2c/ov5640.c @@ -2021,6 +2021,7 @@ static int ov5640_set_fmt(struct v4l2_subdev *sd, struct ov5640_dev *sensor = to_ov5640_dev(sd); const struct ov5640_mode_info *new_mode; struct v4l2_mbus_framefmt *mbus_fmt = &format->format; + struct v4l2_mbus_framefmt *fmt; int ret; if (format->pad != 0) @@ -2038,22 +2039,20 @@ static int ov5640_set_fmt(struct v4l2_subdev *sd, if (ret) goto out; - if (format->which == V4L2_SUBDEV_FORMAT_TRY) { - struct v4l2_mbus_framefmt *fmt = - v4l2_subdev_get_try_format(sd, cfg, 0); + if (format->which == V4L2_SUBDEV_FORMAT_TRY) + fmt = v4l2_subdev_get_try_format(sd, cfg, 0); + else + fmt = &sensor->fmt; - *fmt = *mbus_fmt; - goto out; - } + *fmt = *mbus_fmt; if (new_mode != sensor->current_mode) { sensor->current_mode = new_mode; sensor->pending_mode_change = true; } - if (mbus_fmt->code != sensor->fmt.code) { - sensor->fmt = *mbus_fmt; + if (mbus_fmt->code != sensor->fmt.code) sensor->pending_fmt_change = true; - } + out: mutex_unlock(&sensor->lock); return ret;
