According to https://www.kernel.org/doc/Documentation/gpio/consumer.txt,
- all of the gpiod_set_value_xxx() functions operate with the *logical*
value. So in imx290_power_on() the reset signal should be cleared
(de-asserted) with gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in
imx290_power_off() the value of 1 must be used to apply/assert the reset
to the sensor. In the device tree the reset pin is described as
GPIO_ACTIVE_LOW, and gpiod_set_value_xxx() functions take this into
account,
- when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is
not initialized, and the direction must be set later; using a GPIO
without setting its direction first is illegal and will result in undefined
behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this
asserts the reset signal to the sensor initially).

Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;
- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

From the measured hardware signal, OV5695 reset pin goes high for a
short period of time during boot-up. From the sensor specification, the
reset pin is active low and the DT binding defines the pin as active
low, which means that the values set by the driver are inverted and thus
the value requested in probe ends up high.
Fix it by changing probe to request the reset GPIO initialized to high,
which makes the initial state of the physical signal low.
In addition, DOVDD rising must occur before DVDD rising from spec., but
regulator_bulk_enable() API enables all the regulators asynchronously.
Use an explicit loops of regulator_enable() instead.
For power off sequence, it is required that DVDD falls first. Given the
bulk API does not give any guarantee about the order of regulators,
change the driver to use regulator_disable() instead.
The sensor also requires a delay between reset high and first I2C
transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is
recommended by the vendor. Fix this as well.

When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had
some issues with rcar mipi-csi driver. The sensor never entered into LP-11
state.
The powerup sequence in the datasheet[1] shows the sensor entering into
LP-11 in streaming mode, so to fix this issue transitions are performed
from "streaming -> standby" in the probe() after power up.
With this commit the sensor is able to enter LP-11 mode during power up,
as expected by some CSI-2 controllers.

does not work if the connector does not receive an input signal and the
tvp5150 might not be configured correctly. This misconfiguration leads
into wrong decoded video streams if the tvp5150 gets powered on before
the video signal is present.
Limit the supported sdtv standards according to the actual selected
connector to avoid a misconfiguration.

Bring the device into a working state upon a open/close call. Currently
this involves only the interrupt enable/disable process but can be
extended in the future.

Currently the driver notifies internal subdevs if the signal is locked
or not. This information is also useful for userpace applications e.g. to
switch to another input device upon a signal lost event.
This commit adds the support for the userspace to subscribe to the
V4L2_EVENT_SOURCE_CHANGE and V4L2_EVENT_CTRL events.

As documented in [1] the runtime-pm ops are used to set the device into
a fully 'workable' state. Therefore it can be used to enable or disable
the irqs.

There are several debug prints in the tvp5150_parse_dt() function, which
do not print the prefix, because the v4l2_subdev is not initialized, yet.
Initialize the v4l2_subdev before parsing the device tree to fix the
debug messages.

Since commit 10d5509c8d ("[media] v4l2: remove g/s_crop from video ops")
the 'which' field for set/get_selection must be FORMAT_ACTIVE. There is
no way to try different selections. The patch adds a helper function to
select the correct selection memory space (sub-device file handle or
driver state) which will be set/returned.
The selection rectangle is updated if the format is FORMAT_ACTIVE and
the rectangle position and/or size differs from the current set
rectangle.
