2019-04-22media: vimc: propagate pixel format in the streamHelen Fornazier8-342/+304
Media bus codes were being mapped to pixelformats, which causes a limitation on vimc because not all pixelformats can be mapped to media bus codes. Also, media bus codes are an internal configuration from the device. Userspace only assures media bus codes matches between pads and expects the image in a given pixelformat. So we can allow almost any media bus format to be configured between pads, except for debayer that expects a media bus code of type bayer in the sink pad.

2019-04-22media: atmel: atmel-isc: reworked driver and formatsEugen Hristev1-417/+480
This change is a redesign in the formats and the way the ISC is configured w.r.t. sensor format and the output format from the ISC. I have changed the splitting between sensor output (which is also ISC input) and ISC output. The sensor format represents the way the sensor is configured, and what ISC is receiving. The format configuration represents the way ISC is interpreting the data and formatting the output to the subsystem. Now it's much easier to figure out what is the ISC configuration for input, and what is the configuration for output. The non-raw format can be obtained directly from sensor or it can be done inside the ISC. The controller format list will include a configuration for each format. The old supported formats are still in place, if we want to dump the sensor format directly to the output, the try format routine will detect and configure the pipeline accordingly. This also fixes the previous issues when the raw format was NULL which resulted in many crashes for sensors which did not have the expected/tested formats.

Commit 0650a91499e0 ("media: mtk-vcodec: Correct return type for mem2mem buffer helpers") fixed the return types for mem2mem buffer helper functions by changing a few local variables from vb2_buffer to vb2_v4l2_buffer. However, it left a few accesses to vb2_buffer::planes as-is, accidentally turning them into accesses to vb2_v4l2_buffer::planes and resulting in values being read from/written to the wrong place. Fix this by inserting vb2_buf into these accesses so they mimic their original behavior.

2019-03-29media: davinci-isif: avoid uninitialized variable useArnd Bergmann1-9/+0
clang warns about a possible variable use that gcc never complained about: drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here [-Werror,-Wuninitialized] dm365_vpss_set_pg_frame_size(frame_size); ^~~~~~~~~~ drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here struct vpss_pg_frame_size frame_size; ^ 1 error generated. There is no initialization for this variable at all, and there has never been one in the mainline kernel, so we really should not put that stack data into an mmio register. On the other hand, I suspect that gcc checks the condition more closely and notices that the global isif_cfg.bayer.config_params.test_pat_gen flag is initialized to zero and never written to from any code path, so anything depending on it can be eliminated. To shut up the clang warning, just remove the dead code manually, it has probably never been used because any attempt to do so would have resulted in undefined behavior.

When decoding with resolution changes in between the capture queue has to restart streaming whenever a resolution change occurs. And that would reset last_src_buf as well, which causes a problem if the decoder was stopped by the application. Since last_src_buf is now NULL, the LAST flag is never set for the last capture buffer.
