media: ov5645: Supported external clock is 24MHz

2018-09-26T06:38:00+00:00

[ Upstream commit 4adb0a0432f489c5eb802b33dae7737f69e6fd7a ]

The external clock frequency was set to 23.88MHz by mistake
because of a platform which cannot get closer to 24MHz.
The supported by the driver external clock is 24MHz so
set it correctly and also fix the values of the pixel
clock and link clock.
However allow 1% tolerance to the external clock as this
difference is small enough to be insignificant.

media: videobuf2-core: check for q->error in vb2_core_qbuf()

2018-09-26T06:38:00+00:00

[ Upstream commit b509d733d337417bcb7fa4a35be3b9a49332b724 ]

The vb2_core_qbuf() function didn't check if q->error was set. It is
checked in __buf_prepare(), but that function isn't called if the buffer
was already prepared before with VIDIOC_PREPARE_BUF.

So check it at the start of vb2_core_qbuf() as well.

media: tw686x: Fix oops on buffer alloc failure

2018-09-26T06:38:00+00:00

[ Upstream commit 5a1a2f63d840dc2631505b607e11ff65ac1b7d3c ]

The error path currently calls tw686x_video_free() which requires
vc->dev to be initialized, causing a NULL dereference on uninitizalized
channels.

Fix this by setting the vc->dev fields for all the channels first.

media: s5p-mfc: Fix buffer look up in s5p_mfc_handle_frame_{new, copy_time} functions

2018-09-19T20:43:43+00:00

[ Upstream commit 4faeaf9c0f4581667ce5826f9c90c4fd463ef086 ]

Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time
functions is not working properly for DMA addresses above 2 GiB. As a result
flags and timestamp of returned buffers are not set correctly and it breaks
operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue
flags.

Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks
and sign bit extension these callbacks return incorrect address values,
e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement:

"if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)"

is always false, which breaks looking up capture queue buffers.

To ensure proper matching by address u32 type is used for the DMA
addresses. This should work on all related SoCs, since the MFC DMA
address width is not larger than 32-bit.

Changes done in this patch are minimal as there is a larger patch series
pending refactoring the whole driver.

media: camss: csid: Configure data type and decode format properly

[ Upstream commit c628e78899ff8006b5f9d8206da54ed3bb994342 ]

The CSID decodes the input data stream. When the input comes from
the Test Generator the format of the stream is set on the source
media pad. When the input comes from the CSIPHY the format is the
one on the sink media pad. Use the proper format for each case.

media: dw2102: Fix memleak on sequence of probes

2018-09-19T20:43:39+00:00

[ Upstream commit 299c7007e93645067e1d2743f4e50156de78c4ff ]

Each call to dw2102_probe() allocates memory by kmemdup for structures
p1100, s660, p7500 and s421, but there is no their deallocation.
dvb_usb_device_init() copies the corresponding structure into
dvb_usb_device->props, so there is no use of original structure after
dvb_usb_device_init().

The patch moves structures from global scope to local and adds their
deallocation.

[ Upstream commit 61e641f36ed81ae473177c085f0bfd83ad3b55ed ]

If vpif_probe() fails on v4l2_device_register() then memory allocated
at initialize_vpif() for global vpif_obj.dev[i] become unreleased.

The patch adds deallocation of vpif_obj.dev[i] on the error path and
removes duplicated check on platform_data presence.

media: Revert "[media] tvp5150: fix pad format frame height"

2018-09-09T17:55:53+00:00

commit 1831af092308aa5a59ae61e47494e441c8be6b93 upstream.

This reverts commit 0866df8dffd514185bfab0d205db76e4c02cf1e4.

The v4l uAPI documentation [0] makes clear that in the case of interlaced
video (i.e: field is V4L2_FIELD_ALTERNATE) the height refers to the number
of lines in the field and not the number of lines in the full frame (which
is twice the field height for interlaced formats).

So the original height calculation was correct, and it shouldn't had been
changed by the mentioned commit.
