The aim of the condition is ensuring that the bytesperline value set by the user space application is proper for the given format and adjusting it if isn't. As the depth value of the format description entry is expressed in bits then the bytesperline value needs to be divided, not multiplied, by that value to get the number of bytes required to store single line of image samples.

Reorder quantization tables so that their elements are arranged in the manner reflecting compression quality level that is in accordance with V4L2 documentation, i.e. the larger value of the V4L2_CID_JPEG_COMPRESSION_QUALITY control the better image quality, and thus lower compression quality. The modification allows also to get rid of reverse logic in the s_ctrl callback while assigning user space value to the ctx->compr_quality variable. Signed-off-by:

This patch enables the JPEG codec on S5PV210 and Exynos4210 SoCs. There are some differences in newer versions of the JPEG codec IP on SoCs like Exynos4x12 and Exynos5 series and support for them will be added in subsequent patches. Signed-off-by:

When a fatal error that prevents any further video streaming occurs in a pipeline, all queued buffers must be marked as erroneous and new buffers must be prevented from being queued. Implement this behaviour with a new omap4iss_pipeline_cancel_stream() function that can be used by submodules to cancel streaming. Signed-off-by:

Instead of manually checking whether the CSI2 module is CSI2a or CSI2b in order to select the right subclock to enable/disable, add a subclk field to the iss_csi2 structure, initialize it with the corresponding subclock value and use it at runtime. Signed-off-by:

When a failure to stop a module in the pipeline is detected, the only way to recover is to reset the ISS. However, as other users can be using a different pipeline with other modules, the ISS can't be reset synchronously with the error detection. Keep track of modules that have failed to stop, and reset the ISS accordingly when the last user releases the last reference to the ISS. Refuse to start streaming on a pipeline that contains a crashed module, as the hardware wouldn't work anyway. Modify the omap4iss_pipeline_set_stream() function to record the new ISS pipeline state only when no error occurs, except when stopping the pipeline in which case the pipeline is still marked as stopped.

ISP interrupts are enabled/disabled when starting/stopping the IPIPEIF or resizer. This doesn't permit using the two modules in separate pipelines. Fix it by enabling/disabling the ISP interrupts at the same time as the ISS interrupts, in the ISS device get/put operations. Signed-off-by:
