[media] sh_veu: v4l2_dev wasn't set

2015-04-01T09:56:55+00:00

The v4l2_dev field of struct video_device must be set correctly. This was never done for this driver, so no video nodes were created anymore. Signed-off-by: Hans Verkuil Cc: # for v3.11 and up Signed-off-by: Mauro Carvalho Chehab

[media] media: sh_veu: use vb2_ops_wait_prepare/finish helper

2014-12-22T16:35:13+00:00

This patch drops driver specific wait_prepare() and wait_finish() callbacks from vb2_ops and instead uses the the helpers vb2_ops_wait_prepare/finish() provided by the vb2 core, the lock member of the queue needs to be initalized to a mutex so that vb2 helpers vb2_ops_wait_prepare/finish() can make use of it.

media: platform: drop owner assignment from platform_drivers

2014-10-20T14:20:44+00:00

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

[media] sh_veu: Include media/v4l2-image-sizes.h

2014-08-21T20:25:37+00:00

So we can remove the same defines in the driver code. Signed-off-by: Axel Lin Signed-off-by: Mauro Carvalho Chehab

[media] v4l: Support extending the v4l2_pix_format structure

2014-07-17T15:44:47+00:00

The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

sh_veu: Replace PTR_RET with PTR_ERR_OR_ZERO

Use the PTR_RET() macro to simplify error processing. Signed-off-by: Thomas Meyer Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] sh_veu: fix the buffer size calculation

2013-06-09T00:50:45+00:00

The 'bytesperline' value only indicates the stride of the Y plane if the color format is planar, such as NV12. When calculating the total plane size, the size of CbCr plane must also be considered.

[media] sh_veu: keep power supply until the m2m context is released

2013-06-09T00:50:25+00:00

In the sh_veu driver, only the interrupt handler 'sh_veu_bh' can invoke the v4l2_m2m_job_finish() function. So the hardware must be alive for handling interrupts until returning from v4l2_m2m_ctx_release().

[media] sh_veu: invoke v4l2_m2m_job_finish() even if a job has been aborted

2013-06-09T00:50:13+00:00

v4l2_m2m_job_finish() should be invoked even if the current ongoing job has been aborted since v4l2_m2m_ctx_release() which has issued the job abort may wait until the finish function is invoked.
