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.

media: v4l2-common: Add an helper to apply frmsize constraints

2019-05-29T14:48:34+00:00

The rockchip VPU driver is open-coding this logic which seems pretty
generic. Let's provide an helper to apply the min/max and alignment
constraints on width/height.

media: Introduce helpers to fill pixel format structs

2019-04-22T14:33:06+00:00

Add two new API helpers, v4l2_fill_pixfmt and v4l2_fill_pixfmt_mp,
to be used by drivers to calculate plane sizes and bytes per lines.

Note that driver-specific padding and alignment are not
taken into account, and must be done by drivers using this API.
