Jacopo Mondi ba449bb562 media: i2c: ov5645: Fix media bus format
The ov5645 driver reports as its unique supported format
MEDIA_BUS_FMT_UYVY8_2X8, which is not correct as the sensor
uses the MIPI CSI-2 serial bus.

Fix that by using MEDIA_BUS_FMT_UYVY8_1X16 instead.

Tomi Valkeinen 0d346d2a6f media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.

I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.

This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.

The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:

dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done

Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

Ezequiel Garcia 092e8eb90a media: i2c: ov5645: Fix power sequence
This is mostly a port of Jacopo's fix:

  commit aa4bb8b883
  Author: Jacopo Mondi <jacopo@jmondi.org>
  Date:   Fri Jul 6 05:51:52 2018 -0400

  media: ov5640: Re-work MIPI startup sequence

In the OV5645 case, the changes are:

- At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in
  LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode.
- At set_power(0) time power down MIPI Tx/Rx (in addition to the current
  power down of regulators and clock gating).
- At s_stream time enable/disable the MIPI interface output.

With this commit the sensor is able to enter LP-11 mode during power up,
as expected by some CSI-2 controllers.

Many thanks to Fabio Estevam for his help debugging this issue.

Kieran Bingham e671499303 media: i2c: Convert to new i2c device probe()
The I2C core framework provides a simplified probe framework from commit
b8a1a4cd5a ("i2c: Provide a temporary .probe_new() call-back type").

These drivers do not utilise the i2c_device_id table in the probe, so we
can easily convert them to utilise the simplified i2c driver
registration.
