dma_map_sg() can merge sglist entries, and can thus return a number of mapped entries different than the original value. Don't consider this as an error. Signed-off-by:

The ispmmu_vmap() and ispmmu_vunmap() functions are just wrappers around omap_iommu_vmap() and omap_iommu_vunmap(). Inline them. Signed-off-by:

In preparation for the switch to the DMA API merge the two functions that handle buffer preparation for the USERPTR cases (both page-backed and non page-backed memory). Signed-off-by:

Replace the sglen and sglist fields stored in the buffer structure with an sg_table. This allows using the sg table allocation helper function. Signed-off-by:

As a preparation for the switch from the OMAP IOMMU API to the DMA API move all IOMMU handling code from the video node implementation to the buffers queue implementation. Signed-off-by:

The v4l buffer bytesused field is a value that will be returned to userspace when the buffer gets dequeued. As such it doesn't need to be set early at buffer queue time. Move the assignment to buffer completion in the omap3isp_video_buffer_next() function to prepare for the video buffers queue refactoring. Signed-off-by:

Replace the OMAP-specific IOMMU API usage by the DMA API for FPC. The table is now allocated using dma_alloc_coherent() and the related sg table is retrieved using dma_get_sgtable() for sync operations. Signed-off-by:

The driver stores the IOMMU mapped iovm struct pointer in the buffer structure but only needs the iovm sg table. Store the sg table instead to prepare the migration to the DMA API. Signed-off-by:

The fields store buffer addresses as seen from the device. The first one is used with an external DMA engine while the second one is used with the ISP DMA engine. As they're never used together, merge them. Signed-off-by:

Move code common between the isp_stat_bufs_alloc_dma() and isp_stat_bufs_alloc_iommu() functions to isp_stat_bufs_alloc(). Signed-off-by:

Laurent Pinchart authored
The WARN_ON statements in the buffer allocation functions try to catch conditions where buffers would have already been allocated. As the buffers are explicitly freed right before being allocated this can't happen. Signed-off-by:

Laurent Pinchart authored
The macro is meant to test whether the statistics engine uses an external DMA engine to transfer data or supports DMA directly. As both cases will be supported by DMA coherent buffers rename the macro to ISP_STAT_USES_DMAENGINE for improved clarity. Signed-off-by:

Currently stk1160_read_reg() uses a stack-allocated char to get the read control value. This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.

This patch removes some modprobe parameters, without any reason or description. I was supposed to not merge this patch, but It was merged by mistake. Revert it while nobody provides a good description for such patch. This reverts commit b952662f.

This event indicates that the video device has encountered a source parameter change during runtime. This can typically be a resolution change detected by a video decoder OR a format change detected by an input connector. This needs to be nofified to the userspace and the application may be expected to reallocate buffers before proceeding. The application can subscribe to events on a specific pad or input port which it is interested in. Signed-off-by:

The current names clash with include/linux/leds.h namespace, although there is no compile issue currently this does affect backports.
