v4l: omap3isp: Fix sub-device power management code

2015-10-01T09:36:12Z

commit 9d39f05490115bf145e5ea03c0b7ec9d3d015b01 upstream. Commit 813f5c0ac5cc ("media: Change media device link_notify behaviour") modified the media controller link setup notification API and updated the OMAP3 ISP driver accordingly. As a side effect it introduced a bug by turning power on after setting the link instead of before. This results in sub-devices not being powered down in some cases when they should be. Fix it.

media: omap3isp: preview: Fix the crop margins

2014-05-06T14:59:32Z

commit 8b57b9669aa884ac75b8d09c251d6b1755533c15 upstream. Commit 3fdfedaaa "[media] omap3isp: preview: Lower the crop margins" accidentally changed the previewer's cropping, causing the previewer to miss four pixels on each line, thus corrupting the final image. Restored the removed setting. Signed-off-by: Florian Vaussard Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

[media] omap3isp: ccdc: Don't hang when the SBL fails to become idle

2014-01-07T10:09:30Z

Under abnormal conditions (such as glitches on the HSYNC/VSYNC signals) the CCDC output SBL can fail to become idle. The driver currently logs this condition to the kernel log and doesn't restart the CCDC. This results in CCDC video capture hanging without any notification to userspace. Cancel the pipeline and mark the CCDC as crashed instead of hanging. Userspace will be notified of the problem and will then be able to close and reopen the device to trigger a reset of the ISP.

[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: Fix buffer flags handling when querying buffer

2013-12-18T08:25:04Z

A missing break resulted in all done buffers being flagged with V4L2_BUF_FLAG_QUEUED. Fix it. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[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
