Kees Cook d17dd2db94 [media] media/i2c/tc358743: Initialize timer
This converts to use setup_timer() to set callback and data, though it
doesn't look like this would have worked with timer checking enabled
since no init_timer() was ever called before.

Javier Martinez Canillas 61e220adf6 media: i2c: adv748x: Export I2C device table entries as module aliases
The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, and the driver is only exporting the OF ID
table entries as module aliases.

So if the driver is built as module, autoload won't work since udev/kmod
won't be able to match the registered OF device with its driver module.

Before this patch:

$ modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias
alias:          of:N*T*Cadi,adv7482C*

"Unspecified device" refers to input_name, which makes no sense for IR
TX only devices. So, rename to device_name.

Also make driver_name const char* so that no casts are needed anywhere.

Previously, pixel-rate/(pixels-per-line * lines-per-frame) was

OV sensor is using internal timing and this requires
conversion (internal timing -> PPL) for correct HBLANK calculation.

Now, change pixels-per-line domain from internal sensor clock to
pixels domain. Set HBLANK read-only because fixed PPL is used for all
resolutions. And, use more accurate link-frequency 422.4MHz instead of
rounding down to 420MHz.

Arnd Bergmann fa31c1175f media: i2c: add KConfig dependencies
The new ov5670 driver fails to build when VIDEO_V4L2_SUBDEV_API
or MEDIA_CONTROLLER are disabled:

Gustavo A. R. Silva 281643a2ad media: s5k5baf: remove unnecessary static in s5k5baf_get_selection()
Remove unnecessary static on local variable rtype. Such variable
is initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces
the code size.

This issue was detected using Coccinelle and the following semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the code size. Also,
there is a significant difference in the bss segment. This log is the
output of the size command, before and after the code change:

before:
   text    data     bss     dec     hex filename

Kieran Bingham 3e89586a64 media: i2c: adv748x: add adv748x driver
Provide support for the ADV7481 and ADV7482.

The driver is modelled with 4 subdevices to allow simultaneous streaming
from the AFE (Analog front end) and HDMI inputs though two CSI TX
entities.

The HDMI entity is linked to the TXA CSI bus, whilst the AFE is linked
to the TXB CSI bus.

The driver is based on a prototype by Koji Matsuoka in the Renesas BSP,
and an earlier rework by Niklas Söderlund.
