2014-10-28[media] coda: add CODA7541 JPEG supportPhilipp Zabel1-18/+94
This patch adds JPEG encoding and decoding support for CODA7541, using the BIT processor. Separate JPEG encoder and decoder video devices are created due to different streaming behaviour and different supported pixel formats. The hardware can not change subsampling on the fly, but encode and decode 4:2:2 subsampled JPEG images from and into this format. The CODA7541 JPEG decoder uses the bitstream buffer and thus can run without new buffers queued if there is a buffer in the bitstream. Since there is no standard way to store the colorspace used in JPEGs, and to make v4l2-compliance happy, the JPEG format always reports V4L2_COLORSPACE_JPEG.

2014-10-28[media] coda: split out encoder control setup to specify controls per video ↵Philipp Zabel1-7/+13
device This patch splits the encoder specific controls out of the main control setup function. This way each video device registers only relevant controls.

2014-10-28[media] coda: add coda_video_device descriptorsPhilipp Zabel1-152/+198
Each video device descriptor determines the name, callback ops, and input and output formats on the corresponding video device. This simplifies coda_enum_fmt and coda_try_fmt a bit and will simplify adding separate video devices for JPEG codecs due to the slightly different behavior in the CodaDx6/CODA7542 case and a separate hardware unit on CODA960.

2014-10-28[media] coda: add support for planar YCbCr 4:2:2 (YUV422P) formatPhilipp Zabel1-0/+13
This patch adds support for the three-plane YUV422P format with one luma plane and two horizontally subsampled chroma planes. Signed-off-by: Philipp Zabel <[email protected]> Signed-off-by: Kamil Debski <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2014-10-28[media] coda: add support for partial interleaved YCbCr 4:2:0 (NV12) formatPhilipp Zabel1-0/+8
This patch adds support for the two-plane NV12 format with one luma plane and one interleaved chroma plane. Signed-off-by: Philipp Zabel <[email protected]> Signed-off-by: Kamil Debski <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2014-10-28[media] coda: simplify frame memory control register handlingPhilipp Zabel1-1/+3
Since the firmware newer writes to FRAME_MEM_CTRL, we can initialize it once per context (incidentally, we already do write it in coda_hw_init) and never have to read it back.

2014-10-28[media] coda: add coda_write_base helperPhilipp Zabel1-0/+24
Add a helper function that writes a vb2_buffer's Y, Cb, and Cr plane base addresses of into three consecutive registers. This moves common code out of coda-bit.c.

2014-10-28[media] coda: remove superfluous error message on devm_kzalloc failurePhilipp Zabel1-4/+1

2014-10-28[media] coda: clear aborting flag in stop_streamingPhilipp Zabel1-1/+1
Clearing the aborting flag in stop_streaming is necessary if we want to start streaming again without having to closing and reopening the device. Also, do not explicitly set it in default_params; the context is zeroed by kzalloc anyway.

2014-10-20media: platform: coda: drop owner assignment from platform_driversWolfram Sang1-1/+0

2014-09-26[media] coda: Improve runtime PM supportUlf Hansson1-34/+21
For several reasons it's good practice to leave devices in runtime PM active state while those have been probed. In this cases we also want to prevent the device from going inactive, until the firmware has been completely installed, especially when using a PM domain.

2014-08-21[media] coda: checkpatch cleanupPhilipp Zabel1-11/+23
This patch breaks most long lines, concatenates broken up text strings, and adds or removes parentheses where needed to make checkpatch happy. The long codec list lines and a few 81-wide lines remain.

2014-08-21[media] coda: disable old cropping ioctlsPhilipp Zabel1-0/+5
Since we neither support composing on the OUTPUT side, nor cropping on the CAPTURE side, disable VIDIOC_CROPCAP and VIDIOC_G/S_CROP altogether. This silences a GStreamer warning when GStreamer tries to obtain the pixel aspect ratio using VIDIOC_CROPCAP.

2014-08-21[media] coda: set capture frame size with output S_FMTPhilipp Zabel1-1/+11
This patch makes coda_s_fmt_vid_out propagate the output frame size to the capture side. The GStreamer v4l2videodec only ever calls S_FMT on the output side and then expects G_FMT on the capture side to return a valid format.

2014-08-21[media] coda: fix timestamp list handlingPhilipp Zabel1-0/+2
Lock modification of the timestamp list with bitstream_mutex and do not try to remove a timestamp element if the list is empty. This can happen if the userspace feeds us garbage or multiple encoded frames in a single buffer.

2014-08-21[media] coda: increase max vertical frame size to 1088Philipp Zabel1-7/+6
This patch increases the maximum vertical frame size reported by enum_fmt and accepted by try_fmt/s_fmt from 1080 to 1088. Since for 16x16-pixel macroblocks 1080p will be rounded up to this anyway, we may as well admit that we support it.

2014-08-21[media] coda: skip calling coda_find_codec in encoder try_fmt_vid_outPhilipp Zabel1-5/+6

2014-08-21[media] coda: move per-instance buffer allocation and cleanupPhilipp Zabel1-10/+21

2014-08-21[media] coda: add context opsPhilipp Zabel1-35/+50
