Add support for the Amlogic SM1 platform for the current MPEG1 & MPEG2 support. The SM1 family, very close to the G12A SoCs, has a slighly different power management control, thus needing a separate compatible and family id. Signed-off-by:

Add bindings to support the Amlogic Video Decoder on the Amlogic G12A family. For the G12A family, a supplementary clock is needed to operate the HEVC/VP9 decoder. Signed-off-by:

Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic Video Controller over to YAML schemas. This yaml bindings will then be extended to support new SoCs. Signed-off-by:

When decoding using the CODA internal rotator (for example NV12 capture), currently the value vb2_buf.index + CODA_MAX_FRAMEBUFFERS (19) is written into the DEC_PIC_ROT_INDEX register. At least with firmware version 3.1.1 this causes CODA hangups as soon as the register value reaches 32. Instead, always write CODA_MAX_FRAMEBUFFERS. Signed-off-by:

This patch adds JPEG encoding support for CODA960, handling the JPEG hardware directly. A separate JPEG encoder video device is created due to the separate hardware unit and different supported pixel formats. While the hardware can not change subsampling on the fly, it can encode 4:2:2 subsampled images into JPEGs of the same subsampling. There are two additional tracepoints added to the coda driver that can be used together with the v4l2:v4l2_qbuf and v4l2:v4l2_dqbuf tracepoints to to follow video frames through the mem2mem device when encoding or decoding with the CODA960 JPEG codec: coda:coda_jpeg_run coda:coda_jpeg_done Signed-off-by:Richard Leitner <richard.leitner@skidata.com> [hverkuil-cisco@xs4all.nl: removed unused k and q_data_dst variables] Signed-off-by:

The Huffman bits tables are always 16 bytes long, and they are always followed directly by the values tables, both in hardware and in JPEG files. Just merge the two tables. Signed-off-by:

Always call finish_run when the hardware signals completion. This will allow JPEG contexts to clean up even if job_abort was called during the device_run. Signed-off-by:

With the recent change in ALSA PCM core, the whole open-coded vmalloc buffer handling in this driver can be dropped by replacing with the managed buffer allocation. Also, snd_tm6000_capture_free() is dropped since the check of stream_started flag makes no sense; hw_free callback is guaranteed to be called after the stream gets stopped. Signed-off-by:

In csc_set_coeff() we were previously checking if the format type was V4L2_BUF_TYPE_VIDEO_OUTPUT or V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE as a mean to figure out if the format was multiplanar or not. This was not entirely accurate as the format type could also be a CAPTURE type instead. Fix this by removing the 'switch' construct and replacing them with "if (V4L2_TYPE_IS_MULTIPLANAR(type))" instead. Signed-off-by:

Currently if the allocation of new_buf fails then a null pointer dereference occurs when assiging new_buf->vb. Avoid this by returning early on a memory allocation failure as there is not much more can be done at this point.

It is the vfrontporch of field 1 that is one half-line longer, not the backporch. The order of the vertical signals in an interlaced system is: Field 1: vsync vbackporch active video of field 1 vfrontporch + 0.5 Field 2: il_vsync il_vbackporch - 0.5 active video of field 2 il_vfrontporch Interlaced systems that use HALF_LINE set the il_ fields as follows: il_vfrontporch = vfrontporch il_vsync = vsync il_vbackporch = vbackporch + 1 So the total vertical blanking for field 1 is: vsync + vbackporch + vfrontporch + 0.5 and for field 2: vsync + vbackporch + 1 + vfrontporch - 0.5 == vsync + vbackporch + vfrontporch + 0.5 So each field has the same number of half-lines.

It generates touch patterns simulating single tap, double tap, triple tap, move from left to right, zoom in, zoom out, palm press simulating large area being pressed on screen, and simulating 16 different simultaneous touch points.The values generated are based on behavior of the rmi_f54 driver.

The AVerMedia CE310B is a simple composite + S-Video + stereo audio capture card, and uses only the CX23888 to perform all of these functions. I've tested both video inputs and the audio interface and confirmed that they're all working. However, there are some issues: * Sometimes when I switch inputs the video signal turns black and can't be recovered until the system is rebooted. I haven't been able to determine the cause of this behavior, nor have I found a solution to fix it or any workarounds other than rebooting. * The card sometimes seems to have trouble syncing to the video signal, and some of the VBI data appears as noise at the top of the frame, but I assume that to be a result of my very noisy RF environment and the card's unshielded input traces rather than a configuration issue.
