media: v4l2-mediabus: add support for dual edge sampling

2022-12-07T16:58:46Z

Some devices support sampling of the parallel data at both edges of the interface pixel clock in order to reduce the pixel clock by two. Add a mediabus flag that represents this feature. Signed-off-by: Michael Riesch Reviewed-by: Jacopo Mondi Signed-off-by: Hans Verkuil

media: media/v4l2-core: Add enum V4L2_FWNODE_BUS_TYPE_DPI

2022-05-17T07:09:59Z

As V4L2_FWNODE_BUS_TYPE_PARALLEL is not used for DPI interface, this patch add V4L2_FWNODE_BUS_TYPE_DPI for video DPI interface. Signed-off-by: Xin Ji Reviewed-by: Robert Foss Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-mediabus: Drop V4L2_MBUS_CSI2_CONTINUOUS_CLOCK flag

2022-02-17T08:54:26Z

MIPI CSI-2 continuous and non-continuous clock modes are mutually exclusive. Drop the V4L2_MBUS_CSI2_CONTINUOUS_CLOCK flag and use V4L2_MBUS_CSI2_NONCONTINUOUS_CLOCK only. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-mediabus: Drop legacy V4L2_MBUS_CSI2_CHANNEL_* flags

2022-02-17T08:53:25Z

The V4L2_MBUS_CSI2_CHANNEL_* flags are a legacy API. Only V4L2_MBUS_CSI2_CHANNEL_0 is used, set in a single driver, and never read. Drop those flags. Virtual channel information should be conveyed through frame descriptors instead. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-mediabus: Drop legacy V4L2_MBUS_CSI2_*_LANE flags

The V4L2_MBUS_CSI2_*_LANE flags are a legacy API and are unused. Drop them. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-mediabus: Use structures to describe bus configuration

2022-02-17T08:51:23Z

The media bus configuration is specified through a set of flags, some of which being mutually exclusive. This doesn't scale to express more complex configurations. Improve the API by replacing the single flags field in v4l2_mbus_config by a union of v4l2_mbus_config_* structures. The flags themselves are still used in those structures, so they are kept here. Drivers are however updated to use structure fields instead of flags when already possible. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-fwnode: Move bus config structure to v4l2_mediabus.h

2022-01-28T14:52:41Z

To prepare for usage of the v4l2_fwnode_bus_* data structures to describe bus configuration in the subdev .get_mbus_config() operation, rename the structures with a v4l2_mbus_config_ prefix instead of v4l2_fwnode_bus_, and move them to v4l2_mediabus.h.

media: v4l2-subdev: Drop .set_mbus_config() operation

2022-01-28T14:51:23Z

The .set_mbus_config() operation is deprecated, and nothing in the kernel uses it. Drop it. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: fix kernel-doc markups

2020-11-16T09:31:16Z

Some identifiers have different names between their prototypes and the kernel-doc markup. Seome seems to be due to cut-and-paste related issues. Others need to be fixed, as kernel-doc markups should use this format: identifier - description Acked-by: Sakari Ailus # IPU3 and V4L2 Signed-off-by: Mauro Carvalho Chehab
