is implemented in the driver core and the pinctrl_pm_* API can be used for
switching between the default and the idle state.

"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in

There are lots of drivers that only work when the media controller
and/or the V4L2 subdev APIs are present.
Right now, someone need to first enable those APIs before
using those drivers.
Well, ideally, drivers, should, instead *optionally*
depend on it, in order for PC camera drivers to be able to use
them, but nowadays most drivers are UVC cameras, with don't
require a sensor driver.
So, be it.
Let's instead make them select the MEDIA_CONTROLLER and the
SUBDEV API, in order to make easier for people to be able
of enabling them.

Support for multiplanar and singleplanar formats is mutually exclusive,
at least in practice. In our attempt to unify support for support for
mplane and !mplane in v4l, let's get rid of the
->vidioc_enum_fmt_{vid,out}_cap_mplane() hooks and call
->vidioc_enum_fmt_{vid,out}_cap() instead.

The strncpy() function is being deprecated upstream. Replace
it by the safer strscpy().
While here, replace a few occurences of strlcpy() that were

The check to see if type is V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE is redundant
as this has been already checked at the start of the function and if
it's not that value then -ENOSYS is returned. Hence the sprintf can be
replaced by a simpler string copy.
