The video decoder supports either 8-bit 4:2:2 YUV with discrete syncs
or 8-bit ITU-R BT.656 with embedded syncs output format but currently
BT.656 it's always reported. Allow to configure the format to use via
either platform data or a device tree definition.

After power-up, the tvp5150 decoder is in a unknown state until the
RESETB pin is driven LOW which reset all the registers and restarts
the chip's internal state machine.
The init sequence has some timing constraints and the RESETB signal
can only be used if the PDN (Power-down) pin is first released.
So, the initialization sequence is as follows:
1- PDN (active-low) is driven HIGH so the chip is power-up
2- A 20 ms delay is needed before sending a RESETB (active-low) signal.
3- The RESETB pulse duration is 500 ns.
4- A 200 us delay is needed for the I2C client to be active after reset.
This patch used as a reference the logic in the IGEPv2 board file from
the ISEE 2.6.37 vendor tree.

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.
So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.
The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

Entities should have one or more functions. Calling it as a
type proofed to not be correct, as an entity could eventually
have more than one type.
So, rename the field as function.
Please notice that this patch doesn't extend support for
multiple function entities. Such change will happen when
we have real case drivers using it.

The driver creates two subdevs, one for the image sensor pixel array
(and the related readout logic) and one for an ISP.
The first subdev already uses the MEDIA_ENT_T_V4L2_SUBDEV_SENSOR type,
but the second subdev isn't a sensor pixel array.
So, rename the second subdev as MEDIA_ENT_T_V4L2_SUBDEV_UNKNOWN.

This sensor driver is abusing MEDIA_ENT_T_V4L2_SUBDEV, creating
some subdevs with a non-existing type.
As this is a sensor driver, one of the entries is
MEDIA_ENT_T_CAM_SENSOR. The other one will be using
MEDIA_ENT_T_V4L2_SUBDEV_UNKNOWN, because the subdev is not
any of the already existing types.

With the new API, a link can be either between two PADs or between an interface

So, rename the such function to media_create_pad_link().

Currently, media_entity_init() creates an array with the links,
allocated at init time. It provides a parameter (extra_links)
that would allocate more links than the current needs, but this
is not used by any driver.
As we want to be able to do dynamic link allocation/removal,
we'll need to change the implementation of the links. So,
before doing that, let's first remove that extra unused
parameter, in order to cleanup the interface first.

The cx23888 also moves the following registers around:

0x420 0x418 (expect for bit 29 which has a different meaning)
0x478 0x454
Also drop the set_input code where the scaler is changed: this does not
belong here, changing the input should not change the scaler.
And that's besides the fact that that code is plain wrong.
After this change the cx23888 behaves much better. In particular, calling
set_input no longer changes the saturation to 0, causing a grayscale

The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).
So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
But this means that OF-only drivers needs to have both OF and SPI id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.
To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

Initialization of the ADV7180 chip fails on the Renesas R8A7790-based
Lager board about 50% of the time. This patch resolves the issue by
increasing the minimum delay after reset from 2 ms to 5 ms, following the
recommendation in the ADV7180 datasheet:
"Executing a software reset takes approximately 2 ms. However, it is
recommended to wait 5 ms before any further I2C writes are performed."

Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.
Let's move those i2c specific files to its own subdirectory.
The files to move were produced via the following script:
mkdir include/media/i2c
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done
And the references corrected via this script:
MAIN_DIR="media/"
PREV_DIR="media/"
DIRS="i2c/"
echo "Checking affected files" >&2
for i in $DIRS; do
for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.
In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.
And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.
To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.

manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.
To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

The driver was written with the 'soc_camera' use in mind, however the g_std()
video method was forgotten. Implement it at last...

Hardware interrupts are enabled in the probe function, before the subdev
is registered to its v4l2_device. Until v4l2_device_register_subdev_node
is called, sd->devnode is NULL and v4l2_subdev_notify_event must not be
called.

This driver depends on VIDEO_V4L2_SUBDEV_API and needs to select HDMI.

Commit 256148246852 ("[media] tc358743: support probe from device tree")
failed to explicitly set the direction of the reset gpio. Use the
optional flag of devm_gpiod_get to make up leeway.
This is also necessary because the flag parameter will become mandatory
soon.

sr030pc30_get_fmt() can only succeed if both info->curr_win and
info->curr_fmt are not NULL.
If one of those vars are null, the curent code would call:
ret = sr030pc30_set_params(sd);
If the curr_win is null, it will return -EINVAL, as it would be
expected. However, if curr_fmt is NULL, the function won't
set it.
The code will then try to read from it:
mf->code = info->curr_fmt->code;
mf->colorspace = info->curr_fmt->colorspace;
with obviouly won't work.
This got reported by smatch:
drivers/media/i2c/sr030pc30.c:505 sr030pc30_get_fmt() error: we previously assumed 'info->curr_win' could be null (see line 499)

As the maximum size is 1026, we can't use dynamic var, as it

So, allocate a buffer with the allowed maximum size together with
the state var.
