In this driver there are several entities associated with separate platform or I2C client devices, which may get probed in random order. When the platform device bound to the media device driver is probed all other entity drivers need to be already in place and initialized. If any of them is not, fail the media device probe and return an error indicating we need to be retried once any new driver gets registered. The media device driver probe will not succeed until there are available all needed sub-drivers, as specified in the platform data. While at it, make sure the s5p-csis module (MIPI-CSI receiver driver) does not get unloaded when in use, by guarding its usage with try_module_get/module_put. This patch is a prerequisite for adding the device tree support. It now also allows again to unbind/bind the driver at runtime from user space via sysfs. Signed-off-by:

This patch prevents blocking on DQBUF at a video capture node in some conditions, after STREAOMOFF/STREAMON sequence. The ST_CAPT_SUSPEND flag should not be set during normal stream off, otherwise the capture engine is not properly enabled at stream on. Reported-by:

The MIPI-CSI2 data alignment parameter can be derived from media bus pixel code, so it can be now dropped from the platform data structure. This is a prerequisite for adding the device tree support. Once this patch is merged the corresponding fields will be removed from the drivers' public headers and corresponding board files. Signed-off-by:

Add support for VIDIOC_SUBDEV_S_SELECTION and VIDIOC_SUBDEV_G_SELECTION IOCTLs. They replace functionality provided by VIDIOC_SUBDEV_S_CROP and VIDIOC_SUBDEV_G_CROP IOCTLs and also add new functionality (composing). VIDIOC_SUBDEV_G_CROP and VIDIOC_SUBDEV_S_CROP continue to be supported. Signed-off-by:

There was a bug I2C adapter writes and reads one byte too much. As the most I2C clients has auto-increment register addressing this leads next register from the target register overwritten by garbage data. As a change remove whole register address byte usage and write data directly to the I2C bus without saying what are register address bytes to firmware. Signed-off-by:
