This change do not have a huge effect on the driver as it do not yet support changing the format. Signed-off-by: Niklas Söderlund --- Hello, This change is mostly to align all driver used in the R-Car VIN pipeline to use the same set of API and to make it easier to extend them in tandem going forward. This should be seen as a compliment to Jacopo's larger work in "[PATCH v3 00/11] media: renesas: rcar-csi2: Use the subdev active state" which updates other drivers in the VIN pipeline to use the active state. --- drivers/staging/media/max96712/max96712.c | 36 +++++++++++++++++------ 1 file changed, 27 insertions(+), 9 deletions(-) diff --git a/drivers/staging/media/max96712/max96712.c b/drivers/staging/media/max96712/max96712.c index c44145284aa1..2da65ccd2c57 100644 --- a/drivers/staging/media/max96712/max96712.c +++ b/drivers/staging/media/max96712/max96712.c @@ -242,21 +242,34 @@ static const struct v4l2_subdev_video_ops max96712_video_ops = { .s_stream = max96712_s_stream, }; -static int max96712_get_pad_format(struct v4l2_subdev *sd, - struct v4l2_subdev_state *sd_state, - struct v4l2_subdev_format *format) +static int max96712_init_state(struct v4l2_subdev *sd, + struct v4l2_subdev_state *state) { - format->format.width = 1920; - format->format.height = 1080; - format->format.code = MEDIA_BUS_FMT_RGB888_1X24; - format->format.field = V4L2_FIELD_NONE; + static const struct v4l2_mbus_framefmt default_fmt = { + .width = 1920, + .height = 1080, + .code = MEDIA_BUS_FMT_RGB888_1X24, + .colorspace = V4L2_COLORSPACE_SRGB, + .field = V4L2_FIELD_NONE, + .ycbcr_enc = V4L2_YCBCR_ENC_DEFAULT, + .quantization = V4L2_QUANTIZATION_DEFAULT, + .xfer_func = V4L2_XFER_FUNC_DEFAULT, + }; + struct v4l2_mbus_framefmt *fmt; + + fmt = v4l2_subdev_state_get_format(state, 0); + *fmt = default_fmt; return 0; } +static const struct v4l2_subdev_internal_ops max96712_internal_ops = { + .init_state = max96712_init_state, +}; + static const struct v4l2_subdev_pad_ops max96712_pad_ops = { - .get_fmt = max96712_get_pad_format, - .set_fmt = max96712_get_pad_format, + .get_fmt = v4l2_subdev_get_fmt, + .set_fmt = v4l2_subdev_get_fmt, }; static const struct v4l2_subdev_ops max96712_subdev_ops = { @@ -293,6 +306,7 @@ static int max96712_v4l2_register(struct max96712_priv *priv) long pixel_rate; int ret; + priv->sd.internal_ops = &max96712_internal_ops; v4l2_i2c_subdev_init(&priv->sd, priv->client, &max96712_subdev_ops); priv->sd.flags |= V4L2_SUBDEV_FL_HAS_DEVNODE; priv->sd.entity.function = MEDIA_ENT_F_VID_IF_BRIDGE; @@ -324,6 +338,10 @@ static int max96712_v4l2_register(struct max96712_priv *priv) v4l2_set_subdevdata(&priv->sd, priv); + ret = v4l2_subdev_init_finalize(&priv->sd); + if (ret) + goto error; + ret = v4l2_async_register_subdev(&priv->sd); if (ret < 0) { dev_err(&priv->client->dev, "Unable to register subdevice\n");
