From 07115449919383548d094ff83cc27bd08639a8a1 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Mon, 3 Dec 2018 03:44:16 -0500 Subject: media: ov5640: Fix set format regression The set_fmt operations updates the sensor format only when the image format is changed. 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 --- drivers/media/i2c/ov5640.c | 17 ++++++++--------- 1 file changed, 8 insertions(+), 9 deletions(-) (limited to 'drivers') diff --git a/drivers/media/i2c/ov5640.c b/drivers/media/i2c/ov5640.c index a91d91715d00..807bd0e386a4 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; -- cgit v1.2.3
