media: soc_camera: Move to the staging tree

2019-02-18T17:09:19Z

The SoC camera framework has no functional drivers left, something that has not changed for years. Move the leftovers to the staging tree. Signed-off-by: Sakari Ailus Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: soc_camera_platform: remove obsolete soc_camera test driver

2019-01-21T17:24:56Z

This is a test stub driver for soc_camera. Since soc_camera is being deprecated (and in fact, nobody is using it anymore) there's no sense in keeping this test driver. Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: soc_camera/soc_scale_crop: drop this unused code

With the removal of sh_mobile_ceu_camera.c this code is no longer used and can be removed. Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: sh_mobile_ceu_camera: remove obsolete soc_camera driver

2019-01-21T17:23:26Z

This driver got converted to not depend on soc_camera in commit 32e5a70dc8f4 ("media: platform: Add Renesas CEU driver"). There's no sense in keeping the old version there. Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

Pull new experimental media request API from Mauro Carvalho Chehab: "A new media request API This API is needed to support device drivers that can dynamically change their parameters for each new frame. The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ...

media: platform: Switch to v4l2_async_notifier_add_subdev

2018-10-04T19:55:38Z

Switch all media platform drivers to call v4l2_async_notifier_add_subdev() to add asd's to a notifier, in place of referencing the notifier->subdevs[] array. These drivers also must now call v4l2_async_notifier_init() before adding asd's to their notifiers. There may still be cases where a platform driver maintains a list of asd's that is a duplicate of the notifier asd_list, in which case its possible the platform driver list can be removed, and can reference the notifier asd_list instead. One example of where a duplicate list has been removed in this patch is xilinx-vipp.c. If there are such cases remaining, those drivers should be optimized to remove the duplicate platform driver asd lists. None of the changes to the platform drivers in this patch have been tested. Verify that the async subdevices needed by the platform are bound at load time, and that the driver unloads and reloads correctly with no memory leaking of asd objects.

media: v4l: Remove support for crop default target in subdev drivers

2018-10-03T15:58:24Z

The V4L2 sub-device API does not support the crop default target. A number of drivers apparently still did support this, likely as it was needed by the SoC camera framework. Drop support for the default crop rectaingle in sub-device drivers, and use the bounds rectangle in SoC camera instead.

media: replace strcpy() by strscpy()

The strcpy() function is being deprecated upstream. Replace it by the safer strscpy(). Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: use strscpy() instead of strlcpy()

2018-09-11T17:32:17Z

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings. Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Kees Cook Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
