If CEU driver can not receive data from camera, CETCR has VBP error state. Then, CEU is stopped and cure operation is needed. This patch add VBP error cure operation. Signed-off-by:

The initial soc-camera scaling and cropping implementation turned out to be incompliant with the V4L2 API, e.g., it expected the user to specify cropping in output window pixels, instead of input window pixels. This patch converts the soc-camera core and all drivers to comply with the standard. Signed-off-by:

Remove set_crop soc-camera device method and switch to s_crop from v4l2-subdev video operations. Also extend non-i2c drivers to also hold a pointer to their v4l2-subdev instance in control device driver-data, i.e., in dev_get_drvdata((struct device *)to_soc_camera_control(icd)) Signed-off-by:

Use host-side image scaling when the client fails to set the requested format. We also have to take scaling into account when performing host-side cropping. Similar to cropping we try to use client-side scaling as much as possible to preserve bus bandwidth and optimise the frame-rate. Signed-off-by:

Not all video capture devices can configure arbitrary cropping, whereas the CEU module on SuperH CPUs can crop with pixel precision. However, we want to use camera cropping if possible to save bandwidth and increase the frame-rate. This patch verifies whether the camera managed to crop exactly the requested rectangle, and if not, uses host-side cropping. To be able to crop on CEU we have to preserve camera rectangle too, for which the host_priv member in struct soc_camera_device is used. We now allocate memory dynamically, thus we have to use the .put_formats() method from struct soc_camera_host_ops to free it. Signed-off-by:

Patch [PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer() was not quite correct. It closed a race, but introduced a potential lock-up, if for some reason an interrupt does not come. This has been observed in tests with tw9910. This patch safely dequeues buffers without waiting for their completion. It also moves a buffer state assignment under a spinlock to make it atomic with queuing of the buffer. Signed-off-by:

Convert the soc-camera framework to use the v4l2-(sub)dev API. Start using v4l2-subdev operations. Only a part of the interface between the soc_camera core, soc_camera host drivers on one side and soc_camera device drivers on the other side is replaced so far. The rest of the interface will be replaced in incremental steps, and will require extensions and, possibly, modifications to the v4l2-subdev code. Signed-off-by:

Convert soc-camera core and all drivers to platform device API. We already converted platforms to register a platform device for each soc-camera client, now we remove the compatibility code and switch completely to the new scheme. This is a preparatory step for the v4l2-subdev conversion. Signed-off-by:

This patch modifies the SuperH Mobile CEU driver to support Runtime PM. Driver callbacks for Runtime PM are empty because the device registers are always re-initialized after pm_runtime_get_sync(). The Runtime PM functions replaces the clock framework module stop bit handling in this driver. Signed-off-by:

Currently, if an soc-camera device, connected to the sh_mobile_ceu_camera camera host driver, supports several formats from the UYVY, VYUY, YUYV, YVYU set, the driver would add four NV* formats for each of them. This patch fixes this misbehaviour. Reported-by:

Pixel format requested by the user is not necessarily the same, as what a sensor driver provides. There are situations, when a camera host driver provides the required format, but requires a different format from the sensor. Further, the list of formats, supported by sensors is pretty static and can be pretty good described with a constant list of structures. Whereas decisions, made by camera host drivers to support requested formats can be quite complex, therefore it is better to let the host driver do the work. Signed-off-by:
