[media] omap3isp: Fix kerneldoc for _module_sync_is_stopping and isp_isr()

2014-03-05T20:02:07Z

Use the correct name in the comment describing function omap3isp_module_sync_is_stopping(). isp_isr() never returned IRQ_NONE, remove the comment saying so. Signed-off-by: Peter Meerwald Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Refactor modules stop failure handling

2014-01-07T10:09:15Z

Modules failing to stop are fatal errors for the preview engine only. Flag that condition separately from the other stop failures to prepare support for more fatal errors. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Cancel streaming when a fatal error occurs

2014-01-07T10:08:48Z

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 omap3isp_pipeline_cancel_stream() function that can be used by submodules to cancel streaming.

[media] omap3isp: Use devm_ioremap_resource()

2013-12-18T08:24:41Z

Replace devm_request_mem_region() and devm_ioremap_nocache() with devm_ioremap_resource(). The behaviour remains the same and the code is simplified. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Modify clocks registration to avoid circular references

2013-12-18T08:24:13Z

The clock core code is going to be modified so clk_get() takes reference on the clock provider module. Until the potential circular reference issue is properly addressed, we pass NULL as the first argument to clk_register(), in order to disallow sub-devices taking a reference on the ISP module back trough clk_get(). This should prevent locking the modules in memory. Signed-off-by: Sylwester Nawrocki Signed-off-by: Kyungmin Park Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] media_tree: Fix spelling errors

2013-11-29T16:43:50Z

Fix various spelling errors in strings and comments throughout the media tree. The majority of these were found using Lucas De Marchi's codespell tool.

DMA-API: media: omap3isp: use dma_coerce_mask_and_coherent()

2013-10-31T14:48:52Z

The code sequence: isp->raw_dmamask = DMA_BIT_MASK(32); isp->dev->dma_mask = &isp->raw_dmamask; isp->dev->coherent_dma_mask = DMA_BIT_MASK(32); bypasses the architectures check on the DMA mask. It can be replaced with dma_coerce_mask_and_coherent(), avoiding the direct initialization of this mask. Acked-by: Laurent Pinchart Signed-off-by: Russell King

[media] media: Change media device link_notify behaviour

2013-06-13T01:16:27Z

Currently the media device link_notify callback is invoked before the actual change of state of a link when the link is being enabled, and after the actual change of state when the link is being disabled. This doesn't allow a media device driver to perform any operations on a full graph before a link is disabled, as well as performing any tasks on a modified graph right after a link's state is changed. This patch modifies signature of the link_notify callback. This callback is now called always before and after a link's state change. To distinguish the notifications a 'notification' argument is added to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates notification before link's state change and MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after link flags change.

[media] omap3isp: Defer probe when the IOMMU is not available

2013-06-12T21:27:18Z

When the OMAP3 ISP driver is compiled in the kernel the device can be probed before the corresponding IOMMU is available. Defer the probe in that case, and fix a crash in the error path. Reported-by: Javier Martin Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab
