[media] v4l: omap3isp: Use dma_request_chan_by_mask() to request the DMA channel

2016-11-16T18:14:20+00:00

When requesting the DMA channel it was mandatory that we do not have DMA resource nor valid DMA channel via DT. In this case the dma_request_slave_channel_compat() would fall back and request any channel with SW trigger. The same can be achieved with the dma_request_chan_by_mask() without the misleading use of the DMAengine API - implying that the omap3isp does need to have DMA resource or valid dma binding in DT.

[media] v4l: omap3isp: Fix OF node double put when parsing OF graph

2016-11-16T18:13:39+00:00

When parsing the graph the driver loops over all endpoints using of_graph_get_next_endpoint(). The function handles reference counting of the passed and returned nodes, so the returned node's reference count must not be decreased manually in the normal path. Move the offending of_node_put() call to the error path that requires manual reference count handling. Reported-by: H.

[media] omap3isp: don't break long lines

2016-10-21T11:34:16+00:00

Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } Signed-off-by: Mauro Carvalho Chehab

[media] media: Move media_device link_notify operation to an ops structure

This will allow adding new operations without increasing the media_device structure size for drivers that don't implement any media device operation. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: remove g/s_crop from video ops

2016-08-24T12:46:09+00:00

Replace all calls to g/s_crop by calls to the get/set_selection pad ops. Remove the old g/s_crop video ops since they are now no longer used. The cropcap video op is now only used to pass pixelaspect information, and is only needed if the pixelaspect is not 1:1.

[media] vb2: replace void alloc_ctxs by struct device alloc_devs

2016-07-08T17:45:07+00:00

Make this a proper typed array. Drop the old allocate context code since that is no longer used. Note that the memops functions now get a struct device pointer instead of the struct device ** that was there initially (actually a void pointer to a struct containing only a struct device pointer). This code is now a lot cleaner. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Cc: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] media: Rename is_media_entity_v4l2_io to is_media_entity_v4l2_video_device

2016-04-13T20:20:48+00:00

All users of is_media_entity_v4l2_io() (the exynos4-is, omap3isp, davince_vpfe and omap4iss drivers and the v4l2-mc power management code) use the function to check whether entities are video_device instances, either to ensure they can cast the entity to a struct video_device, or to count the number of video nodes users. The purpose of the function is thus to identify whether the media entity instance is an instance of the video_device object, not to check whether it can perform I/O. Rename it accordingly, we will introduce a more specific is_media_entity_v4l2_io() check when needed.
