Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

This driver returns an error if unsupported media bus pixel code is
requested by VIDIOC_SUBDEV_S_FMT.
But according to Documentation/media/uapi/v4l/vidioc-subdev-g-fmt.rst,
Drivers must not return an error solely because the requested format
doesn't match the device capabilities. They must instead modify the
format to match what the hardware can provide.
So select default format code and return success in that case.
This is detected by v4l2-compliance.

In preparation for adding asynchronous subdevice support to the driver,
don't acquire v4l2_clk from the driver .probe() callback as that may
fail if the clock is provided by a bridge driver which may be not yet
initialized. Move the v4l2_clk_get() to ov6650_video_probe() helper
which is going to be converted to v4l2_subdev_internal_ops.registered()
callback, executed only when the bridge driver is ready.

After removal of clock_start() from before soc_camera_init_i2c() in
soc_camera_probe() by commit 9aea470b399d ("[media] soc-camera: switch
I2C subdevice drivers to use v4l2-clk") introduced in v3.11, the ov6650
driver could no longer probe the sensor successfully because its clock
was no longer turned on in advance. The issue was initially worked
around by adding that missing clock_start() equivalent to OMAP1 camera
interface driver - the only user of this sensor - but a propoer fix
should be rather implemented in the sensor driver code itself.
Fix the issue by inserting a delay between the clock is turned on and
the sensor I2C registers are read for the first time.
Tested on Amstrad Delta with now out of tree but still locally
maintained omap1_camera host driver.

The exposure control is clustered with the autoexposure control and
flagged as volatile, but the g_volatile_ctrl() doesn't handle
V4L2_CID_EXPOSURE_AUTO. So, the value of the exposure control can't be
read in autoexposure mode.
This enables to get the exposure control in autoexposure mode by making
ov7740_get_volatile_ctrl() deal with V4L2_CID_EXPOSURE_AUTO.
This also sets the exposure control as volatile by specifying the
argument to v4l2_ctrl_auto_cluster() instead of manually flagging it.

As warned by smatch:
drivers/media/i2c/imx214.c:591 imx214_set_format() warn: variable dereferenced before check 'format' (see line 589)
It turns that the code at imx214_set_format() has support for being
called with the format being NULL. I've no idea why, as it is only
called internally with the pointer set, and via subdev API (with
should also set it).
Also, the entire logic there depends on having format != NULL, so
just remove the bogus broken support for a null format.

Since commit 3d6a8fe25605 ("media: ov7670: hook s_power onto v4l2 core"),
the device is actually powered off while the video stream is stopped.
So now set_format and s_frame_interval could be called while the device
is powered off, but these callbacks try to change the register settings
at this time.
The frame format and framerate will be restored right after power-up, so
we can just postpone applying these changes at these callbacks if the
device is not powered up.

The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(),
and this makes this device's runtime PM usage count a negative value.
The ov7740_set_ctrl() tries to do something only if the device's runtime
PM usage counter is nonzero.
ov7740_set_ctrl()
{
if (!pm_runtime_get_if_in_use(&client->dev))
return 0;
<do something>;
pm_runtime_put(&client->dev);
return ret;
}
However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup()
while the runtime PM of this device is not yet enabled. In this case,
the pm_runtime_get_if_in_use() returns -EINVAL (!= 0).
Therefore we can't bail out of this function and the usage count is
decreased by pm_runtime_put() without increment.
This fixes this problem by enabling the runtime PM of this device before
v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called
when the runtime PM is enabled.

The register value lists for all the supported resolution settings all
include a register address/value pair for setting the JPEG compression
mode. With the exception of 1080p (which sets mode 2), all resolutions
use mode 3.
The only difference between mode 2 and mode 3 is that mode 2 may have
padding data on the last line, while mode 3 does not add padding data.
As these register values were from dumps of running systems, and the
difference between the modes is quite small, using mode 3 for all
configurations should be OK.

When compression is turned on, the on-bus data is framed according to
the compression mode, and the height and width set in VFIFO_VSIZE and
VFIFO_HSIZE. If these are not updated correctly, the sensor will send
data framed in a manner unexpected by the capture interface, such as
having more bytes per line than expected, and having the extra data
dropped. This ultimately results in corrupted data.
Set the two values when the media bus is configured for JPEG data,
meaning the sensor would be in JPEG mode.

The OV5640 driver currently supports a static color bar pattern with a
small vertical gamma gradient. The hardware also supports a color square
pattern, as well as having a rolling bar for dynamic sequences.
Add three more test patterns:
- color bars with a rolling bar (but without the gamma gradient)
- static color squares
- color squares with a rolling bar

The transparent feature for test patterns blends the test pattern with
an actual captured image. This makes the result non-static, subject to
changes in the sensor's field of view.
Test patterns should be predictable and deterministic, even if they are
dynamic patterns. Disable the transparent feature of the test pattern.

The OV5640 can generate many types of test patterns, some with

The OV5640 has many options for generating test patterns. Unfortunately
there is only one V4L2 control for it. Thus the driver would need to
list some or all combinations.
Move the test_pattern_menu list before the ov5640_set_ctrl_test_pattern
function that programs the hardware. This would allow us to add a
matching list of values to program into the hardware, while keeping the
two lists together for ease of maintenance.

The ADV748x is currently reset by writting a small table of registers to
the device.
The table lacks documentation and contains magic values to perform the
actions, including using a fake register address to introduce a delay
loop.
Remove the table, and convert to code, documenting the purpose of the
specific writes along the way.

When the adv748x driver is informed about a link being created from HDMI or
AFE to a CSI-2 TX output, the 'link_setup()' callback is invoked. Make
sure to implement proper routing management at link setup time, to route
the selected video stream to the desired TX output.

Both the AFE and HDMI s_stream routines (adv748x_afe_s_stream() and
adv748x_hdmi_s_stream()) have to enable the CSI-2 TX they are streaming video
data to.
With the introduction of dynamic routing between HDMI and AFE entities to
TXA, the video stream sink needs to be set at run time, and not statically
selected as the s_stream functions are currently doing.
To fix this, store a reference to the active CSI-2 TX sink for both HDMI and
AFE sources, and operate on it when starting/stopping the stream.

The power_up_tx() procedure needs to set a few registers conditionally to
the selected video source, but it currently checks for the provided tx to
be either TXA or TXB.
With the introduction of dynamic routing between HDMI and AFE entities to
TXA, checking which TX the function is operating on is not meaningful anymore.
To fix this, store the subdevice of the source providing video data to the
CSI-2 TX in the 'struct adv748x_csi2' representing the TX and check on it.
