Simplify the driver by using the m2m ioctl and vb2 helpers. Signed-off-by:
-
Sylwester Nawrocki authored
This patch adds ioctl helpers to the V4L2 mem-to-mem API, so we can avoid several ioctl handlers in the mem-to-mem video node drivers that are simply a pass-through to the v4l2_m2m_* calls. These helpers will only be useful for drivers that use same mutex for both OUTPUT and CAPTURE queue, which is the case for all currently in tree v4l2 m2m drivers. In order to use the helpers the drivers are required to use struct v4l2_fh. Signed-off-by:

Mark pads that must be connected. Signed-off-by:
-
Sakari Ailus authored
Do not allow streaming if a pad with MEDIA_PAD_FL_MUST_CONNECT flag is not connected by an active link. This patch makes it possible to avoid drivers having to check for the most common case of link state validation: a sink pad that must be connected. Signed-off-by:
-

Pads that set this flag must be connected by an active link for the entity to stream. Signed-off-by:

The ioctl is (at least currently) mandatory. Signed-off-by:

The pad::get_fmt call must be protected by a mutex, but preparing its arguments doesn't need to be. Move the non-critical code out of the mutex-protected section. Signed-off-by:

Translating -ENOIOCTLCMD to -EINVAL is invalid, the correct ioctl return value is -ENOTTY. Signed-off-by:
-
Laurent Pinchart authored
The remote subdev of any video node in the OMAP4 ISS is an internal subdev that is guaranteed to implement get_fmt. Don't check the return value for -ENOIOCTLCMD, as this can't happen. Signed-off-by:

Timestamps use the monotonic clock, configure the vb2 queue accordingly. Signed-off-by:

Laurent Pinchart authored
The vb2 queue already keeps track of the streaming state, there's no need to duplicate that in the driver. Signed-off-by:

Instead of using the extended control API internally to get the sensor pixel rate, use the dedicated in-kernel APIs (find the control with v4l2_ctrl_find() and get its value with v4l2_ctrl_g_ctrl_int64()). Signed-off-by:

This adds a very simplistic driver to utilize the CSI2A interface inside the ISS subsystem in OMAP4, and dump the data to memory. Check Documentation/video4linux/omap4_camera.txt for details. This commit adds and updates Kconfig's and Makefile's, as well as a TODO list. Signed-off-by:

This commit adds resizer support. [Port the driver to v3.12-rc3, including the following changes - Don't include plat/ headers - Don't use cpu_is_omap44xx() macro - Don't depend on EXPERIMENTAL - Fix s_crop operation prototype - Update link_notify prototype - Rename media_entity_remote_source to media_entity_remote_pad] Signed-off-by:
