These patches fix several issues in soc-camera drivers, preparing a
cleaner base for v4l2-async patches.
Thanks

OTOH, holding .video_lock in soc_camera_open() isn't enough to protect the host during its building of the pipeline, because .video_lock is per soc-camera device. If, e.g. more than one sensor can be attached to a host and the user tries to open both device nodes simultaneously, host's .add() method can be called simultaneously for both sensors. Fix these problems by holding list_lock instead of .host_lock in scan_add_host() and taking it shortly at the beginning of soc_camera_open(), and using .host_lock to protect host's .add() and .remove() operations only.

To make subdevice driver re-use simpler, split it into a host and a subdevice parts. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> --- v2: following an off-list discussion with Laurent, .add_device() and .del_device() callbacks are moved over from the subdevice part of the platform data to the host part. drivers/media/i2c/soc_camera/imx074.c | 14 ++-- drivers/media/i2c/soc_camera/mt9m001.c | 38 ++++---- drivers/media/i2c/soc_camera/mt9m111.c | 21 ++-- drivers/media/i2c/soc_camera/mt9t031.c | 22 ++-- drivers/media/i2c/soc_camera/mt9t112.c | 18 ++-- drivers/media/i2c/soc_camera/mt9v022.c | 36 ++++---- drivers/media/i2c/soc_camera/ov2640.c | 12 +- drivers/media/i2c/soc_camera/ov5642.c | 16 ++-- drivers/media/i2c/soc_camera/ov6650.c | 16 ++-- drivers/media/i2c/soc_camera/ov772x.c | 14 ++-- drivers/media/i2c/soc_camera/ov9640.c | 12 +- drivers/media/i2c/soc_camera/ov9740.c | 14 ++-- drivers/media/i2c/soc_camera/rj54n1cb0c.c | 24 +++--- drivers/media/i2c/soc_camera/tw9910.c | 18 ++-- drivers/media/platform/soc_camera/soc_camera.c | 98 ++++++++++--------- .../platform/soc_camera/soc_camera_platform.c | 2 +- include/media/soc_camera.h | 102 ++++++++++++++++---- include/media/soc_camera_platform.h | 10 ++- 18 files changed, 279 insertions(+), 208 deletions(-) diff --git a/drivers/media/i2c/soc_camera/imx074.c b/drivers/media/i2c/soc_camera/imx074.c index f8534ee..1c06571 100644 --- a/drivers/media/i2c/soc_camera/imx074.c +++ b/drivers/media/i2c/soc_camera/imx074.c @@ -271,9 +271,9 @@ static int imx074_g_chip_ident(struct v4l2_subdev *sd, static int imx074_s_power(struct v4l2_subdev *sd, int on) { struct i2c_client *client = v4l2_get_subdevdata(sd); - struct soc_camera_link *icl = soc_camera_i2c_to_link(client); + struct soc_camera_subdev_desc *ssdd = soc_camera_i2c_to_desc(client); - return soc_camera_set_power(&client->dev, icl, on); + return soc_camera_set_power(&client->dev, ssdd, on); } static int imx074_g_mbus_config(struct v4l2_subdev *sd, @@ -430,10 +430,10 @@ static int imx074_probe(struct i2c_client *client, { struct imx074 *priv; struct i2c_adapter *adapter = to_i2c_adapter(client->dev.parent); - struct soc_camera_link *icl = soc_camera_i2c_to_link(client); + struct soc_camera_subdev_desc *ssdd = soc_camera_i2c_to_desc(client); int ret; - if (!icl) { + if (!ssdd) { dev_err(&client->dev, "IMX074: missing platform data!\n"); return -EINVAL; } @@ -464,10 +464,10 @@ static int imx074_probe(struct i2c_client *client, static int imx074_remove(struct i2c_client *client) { struct imx074 *priv = to_imx074(client); - struct soc_camera_link *icl = soc_camera_i2c_to_link(client); + struct soc_camera_subdev_desc *ssdd = soc_camera_i2c_to_desc(client); - if (icl->free_bus) - icl->free_bus(icl); + if (ssdd->free_bus) + ssdd->free_bus(ssdd); kfree(priv); return 0; diff --git a/drivers/media/i2c/soc_camera/mt9m001.c b/drivers/media/i2c/soc_camera/mt9m001.c index 19f8a07..9ae7066 100644 --- a/drivers/media/i2c/soc_camera/mt9m001.c +++ b/drivers/media/i2c/soc_camera/mt9m001.c @@ -23,7 +23,7 @@ /* * mt9m001 i2c address 0x5d * The platform has to define struct i2c_board_info objects and link to them - * from struct soc_camera_link + * from struct soc_camera_host_desc */ /* mt9m001 selected register addresses */ @@ -380,9 +380,9 @@ static int mt9m001_s_register(struct v4l2_subdev *sd, static int mt9m001_s_power(struct v4l2_subdev *sd, int on) { struct i2c_client *client = v4l2_get_subdevdata(sd); - struct soc_camera_link *icl = soc_camera_i2c_to_link(client); + struct soc_camera_subdev_desc *ssdd = soc_camera_i2c_to_desc(client); - return soc_camera_set_power(&client->dev, icl, on); + return soc_camera_set_power(&client->dev, ssdd, on); } static int mt9m001_g_volatile_ctrl(struct v4l2_ctrl *ctrl) @@ -482,7 +482,7 @@ static int mt9m001_s_ctrl(struct v4l2_ctrl *ctrl) * Interface active, can use i2c.

This can lead to repeated regulator requesting, if the host driver is re-probed. Move the call to platform device probing to avoid this.
