media: v4l: common: Fix naming of v4l2_get_link_rate

2021-01-07T14:47:52+00:00

Rename v4l2_get_link_rate() as v4l2_get_link_freq(). What the function
returns is the frequency of the link; rename it to reflect the name of the
control where the information is obtained.

media: vivid: Add support to the CSC API

2020-09-26T08:21:34+00:00

The CSC API (Colorspace conversion) allows userspace to try
to configure the colorspace, transfer function, Y'CbCr/HSV encoding
and the quantization for capture devices. This patch adds support
to the CSC API in vivid.
Using the CSC API, userspace is allowed to do the following:

- Set the colorspace.
- Set the xfer_func.
- Set the ycbcr_enc function for YUV formats.
- Set the hsv_enc function for HSV formats
- Set the quantization for YUV and RGB formats.

media: v4l2: abstract timeval handling in v4l2_buffer

2020-01-03T14:43:35+00:00

As a preparation for adding 64-bit time_t support in the uapi,
change the drivers to no longer care about the format of the
timestamp field in struct v4l2_buffer.

The v4l2_timeval_to_ns() function is no longer needed in the
kernel after this, but there is userspace code relying on
it to be part of the uapi header.

media: v4l2-common: add pixel encoding support

2019-10-10T16:53:23+00:00

It is often useful to figure out if a pixel_format is either YUV or RGB
especially for driver who can perform the pixel encoding conversion.

Instead of having each driver implement its own "is_this_yuv/rgb"
function based on a restricted set of pixel value, it is better to do
this in centralized manner.

We therefore add a pixel_enc member to the v4l2_format_info structure to
quickly identify the related pixel encoding.
And add helper functions to check pixel encoding.

media: v4l2-core: move i2c helpers out of v4l2-common.c

2019-08-26T13:50:48+00:00

Separate the i2c helpers to v4l2-i2c.c, in order to get rid
of the ifdefery. No functional changes intended, this is
just a cosmetic change to organize the code better.

Given I2C is a tristate symbol, a hidden boolean symbol
is introduced, to make the conditional build easier.
