[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.

[media] v4l: omap3isp: Use V4L2 graph PM operations

Power on devices represented by entities in the graph through the pipeline state using V4L2 graph PM operations instead of what was in the omap3isp driver. Signed-off-by: Sakari Ailus Cc: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Check v4l2_of_parse_endpoint() return value

The v4l2_of_parse_endpoint() function can fail so check the return value. Signed-off-by: Javier Martinez Canillas Acked-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l: omap3isp: Fix data lane shift configuration

2016-01-25T10:29:50+00:00

The data-shift DT property speficies the number of bits to be shifted, but the driver still interprets the value as a multiple of two bits as used by now removed platform data support. Fix it. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] v4l: omap3isp: preview: Mark output buffer done first

2016-01-25T10:29:06+00:00

The sequence number counter is incremented on each output buffer, and that incremented value is used as the sequence number of that buffer. The input buffer sequence numbering is based just on reading the same counter. If the input buffer is marked done first, its sequence number ends up being that of the output buffer - 1. This is how the resizer works as well. Signed-off-by: Sakari Ailus Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l: omap3isp: Fix handling platform_get_irq result

2016-01-25T10:28:41+00:00

The function can return negative value. The problem has been detected using proposed semantic patch scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].

[media] v4l: omap3isp: use vb2_buffer_state enum for vb2 buffer state

2016-01-25T10:28:15+00:00

use the vb2_buffer_state enum for assigning the state of the vb2 buffer, along side making isp_pipeline_state state variable local to the block. This fixes the following sparse warning as well: drivers/media/platform/omap3isp/ispvideo.c:497:35: warning: mixing different enum types drivers/media/platform/omap3isp/ispvideo.c:497:35: int enum isp_pipeline_state versus drivers/media/platform/omap3isp/ispvideo.c:497:35: int enum vb2_buffer_state Signed-off-by: Lad, Prabhakar Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l: omap3isp: Return buffers back to videobuf2 if pipeline streamon fails

Move the starting of the sensor from the VIDIOC_STREAMON handler to the videobuf2 queue op start_streaming. This avoids failing starting the stream after vb2_streamon() has already finished. Signed-off-by: Sakari Ailus Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l: omap3isp: Fix module autoloading

2016-01-25T10:21:12+00:00

Platform drivers needs to export the OF id table and this be built into the module or udev will not have the necessary information to autoload the driver module when the device is registered via OF.
