smiapp_replace_limit_at() function is not called by the driver. This was detected by sparse as: drivers/media/i2c/smiapp/smiapp-quirk.c:64:5: warning: symbol 'smiapp_replace_limit_at' was not declared. Should it be static? Signed-off-by:

This patch adds driver for Samsung S5K4ECGX image sensor with an embedded SoC ISP. The driver only implements preview operation mode and still capture (snapshot) and face detection features are missing now. Following controls are supported: contrast, saturation, brightness, sharpness. Signed-off-by:

New mem-to-mem video drivers should use V4L2_CAP_VIDEO_M2M capability, rather than ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags, as outlined in commit a1367f1b. Acked-by:

channel_first_int[][] variable is used as a flag for the ISR, This flag was being set after enabling the interrupts, There where situations when the isr occurred even before the flag was set dues to which it was causing the application hang. This patch sets channel_first_int[][] flag just before enabling the interrupt. Reported-by:

This fixes a failure in vb2_qbuf in user pointer mode where __qbuf_userptr checks if the buffer queued by userspace is large enough. The failure would happen if coda_queue_setup was called with empty fmt (and thus set the expected buffer size to the maximum resolution), and userspace queues buffers of smaller size - corresponding to the negotiated dimensions - were queued. Explicitly setting sizeimage to the value negotiated via s_fmt fixes the issue. Signed-off-by:

Determining the next free instance just by incrementing and decrementing an instance counter does not work: if there are two instances opened, 0 and 1, and instance 0 is released, the next call to coda_open will create a new instance with index 1, but instance 1 is already in use. Instead, scan a bitfield of active instances to determine the first free instance index. Signed-off-by:

job_ready is supposed to signal whether a context is ready to be added to the job queue, not whether the CODA is ready to run it immediately. Calling v4l2_m2m_job_finish at the end of coda_irq_handler already guarantees that the coda is ready when v4l2-mem2mem eventually tries to run the next queued job. Signed-off-by:

Some codecs running on CODA need internal framebuffers for reference and reconstructed frames. Allocate them separately, and do not use the input vb2_buffers: those will be handed off to userspace regularly, and there is no way to signal to the CODA which of the registered framebuffers are off limits. As a consequence, userspace is now free to choose the number of v4l2 buffers. This patch also includes the code to set up the parameter buffer for CODA7 and above with 64-bit AXI bus width.

This uses the ARCH_MXC specific iram_alloc API to allocate a work buffer in the SoC's on-chip SRAM and sets up the AXI_SRAM_USE register. In the future, the allocation will be converted to use the genalloc API. Signed-off-by:

Check against q->fileio to see if the queue owner should be set or not. The former check against the return value of read or write is wrong, since read/write can return an error, even if the queue is in streaming mode. For example, EAGAIN when in non-blocking mode. Signed-off-by:

The ioctl validity checks have been improved and now take vfl_type and vfl_dir into account. During the 2012 Media Workshop it was decided that these improved v4l2 core checks should be added as they simplified drivers and made drivers behave consistently. Signed-off-by:

While the documentation says that VIDIOC_CROPCAP is compulsory for all video capture and output devices, in practice VIDIOC_CROPCAP is only implemented for devices that can do cropping and/or scaling. Update the documentation to no longer require VIDIOC_CROPCAP if the driver does not support cropping or scaling or non-square pixels. Signed-off-by:
