2020-02-27media: venus: cache vb payload to be used by clock scalingStanimir Varbanov
Instead of iterate over previously queued buffers in clock scaling code do cache the payload in instance context structure for later use when calculating new clock rate. This will avoid to use spin locks during buffer list iteration in clock_scaling.

Avoid adding an extra columns when describing unions in the documentation. That makes it much harder to read. See e.g. VIDIOC_QUERY_EXT_CTRLS. Instead start off a union with 'union {' and end it with an extra row containing '}'. This leaves a lot more space for the description of the fields.

2020-02-24media: hantro: Write quantization table registers in increasing addresses orderAndrzej Pietrasiewicz
Luma and chroma qtables need to be written into two 16-register blocks, each table consisting of 64 bytes total. The blocks are contiguous and start at offset 0 for luma and at offset 0x40 for chroma. The seemingly innocent optimization of writing the two blocks using one loop causes side effects which result in improper values of quantization tables being used by the hardware during encoding. Visually this results in macroblocking artifacts around contrasting edges in encoded images. The artifacts look like horizontally flipped shadows of the said edges. Changing the write operations to non-relaxed variant doesn't help. This patch removes this premature optimization and after this change the macroblocking artifacts around contrasting edges are gone.

2020-02-24media: hantro: Write the quantization tables in proper orderAndrzej Pietrasiewicz
The quantization tables as defined in the file (luma_q_table, chroma_q_table) are in fact in linear order. The JPEG file header, which is not generated by the hardware, but must be programatically created with the CPU, expects the table in zigzag order. On the other hand, the hardware doesn't expect neither linear, nor zigzag order. Instead it expects the quantization tables in vertical groups of four quantization parameters, and the groups are organized in blocks of two vertically adjacent groups. On top of that the blocks must be provided to the hardware in this order: leftmost top block, leftmost bottom block, second leftmost top block, second leftmost bottom block and so on. So, if this is the quantization table in linear order: 0x10, 0x0b, 0x0a, 0x10, 0x18, 0x28, 0x33, 0x3d, 0x0c, 0x0c, 0x0e, 0x13, 0x1a, 0x3a, 0x3c, 0x37, 0x0e, 0x0d, 0x10, 0x18, 0x28, 0x39, 0x45, 0x38, 0x0e, 0x11, 0x16, 0x1d, 0x33, 0x57, 0x50, 0x3e, 0x12, 0x16, 0x25, 0x38, 0x44, 0x6d, 0x67, 0x4d, 0x18, 0x23, 0x37, 0x40, 0x51, 0x68, 0x71, 0x5c, 0x31, 0x40, 0x4e, 0x57, 0x67, 0x79, 0x78, 0x65, 0x48, 0x5c, 0x5f, 0x62, 0x70, 0x64, 0x67, 0x63 then the hardware expects this in its consecutive registers: 0x100c0e0e, 0x0b0c0d11, 0x12183148, 0x1623405c, 0x0a0e1016, 0x1013181d, 0x25374e5f, 0x38405762, and so on. Consequently, the same area of memory cannot be used both for dumping it into the JPEG file header and writing its contents to the hardware registers. Instead, a separate pair of arrays is added for properly reordered quantization tables, to be read with get_unaligned_be32() and linearly written to the registers. The "ctx" parameter is not needed any more for hantro_jpeg_get_qtable().

2020-02-24media: rename VFL_TYPE_GRABBER to _VIDEOHans Verkuil
We currently have the following devnode types: enum vfl_devnode_type { VFL_TYPE_GRABBER = 0, VFL_TYPE_VBI, VFL_TYPE_RADIO, VFL_TYPE_SUBDEV, VFL_TYPE_SDR, VFL_TYPE_TOUCH, VFL_TYPE_MAX /* Shall be the last one */ }; They all make sense, except for the first: GRABBER really refers to /dev/videoX devices, which can be capture, output or m2m, so 'grabber' doesn't even refer to their function anymore. Let's call a spade a spade and rename this to VFL_TYPE_VIDEO.

2020-02-24media: dib0700: fix rc endpoint lookupJohan Hovold
Make sure to use the current alternate setting when verifying the interface descriptors to avoid submitting an URB to an invalid endpoint. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

commit 1b976fc6d684 ("media: b2c2-flexcop-usb: add sanity checking") added an endpoint sanity check to address a NULL-pointer dereference on probe. Unfortunately the check was done on the current altsetting which was later changed. Fix this by moving the sanity check to after the altsetting is changed.

The hardware does not support capturing the field types V4L2_FIELD_SEQ_TB and V4L2_FIELD_SEQ_BT. To capture in these formats the driver needs to adjust the offset of the capture buffer and capture twice to each vb2 buffer.
