[media] media: omap3isp: hist: Move histogram DMA to DMA engine

2015-04-02T19:37:13Z

Replace the custom OMAP DMA API usage by DMA engine. Feature-wise the driver has lost the ability to get notified of DMA transfers failure through the completion handler, as the DMA engine API doesn't expose that status information.

[media] omap3isp: Remove boilerplate disclaimer and FSF address

2014-08-21T20:25:12Z

We don't want to modify all source files the day the FSF moves. Signed-off-by: Laurent Pinchart Tested-by: Enrico Butera Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: stat: Use the DMA API

2014-05-25T14:10:50Z

Replace the OMAP-specific IOMMU API usage by the DMA API. All buffers are now allocated using dma_alloc_coherent() and the related sg table is retrieved using dma_get_sgtable() for sync operations. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: stat: Store sg table in ispstat_buffer

2014-05-25T14:10:02Z

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: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: stat: Merge dma_addr and iommu_addr fields

2014-05-25T14:09:25Z

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: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: stat: Share common code for buffer allocation

2014-05-25T14:07:45Z

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 Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: stat: Remove impossible WARN_ON

2014-05-25T14:06:49Z

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 Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: stat: Rename IS_COHERENT_BUF to ISP_STAT_USES_DMAENGINE

2014-05-25T14:05:38Z

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.
