The core helper v4l2_i2c_subdev_init() already assignees the subdevices
dev pointer to the device associated with the i2c client passed to it.
And 'imx290->dev' is assigned to '&client->dev' already in probe before
calling imx290_subdev_init().
Remove the duplicated open-coded assignment in the driver, there is no
reason to do it twice.

ov2659_probe() doesn't properly free control handler resources in failure

Hynix hi556 support 8 test pattern modes:
hi556_test_pattern_menu[] = {
{
"Disabled",
"Solid Colour",
"100% Colour Bars",
"Fade To Grey Colour Bars",
"PN9",
"Gradient Horizontal",
"Gradient Vertical",
"Check Board",
"Slant Pattern",
}
The test pattern is set by a 8-bit register according to the
specification.
+--------+-------------------------------+
| BIT[0] | Solid color |
+--------+-------------------------------+
| BIT[1] | Color bar |
+--------+-------------------------------+
| BIT[2] | Fade to grey color bar |
+--------+-------------------------------+
| BIT[3] | PN9 |
+--------+-------------------------------+
| BIT[4] | Gradient horizontal |

| BIT[5] | Gradient vertical |
+--------+-------------------------------+
| BIT[6] | Check board |
+--------+-------------------------------+
| BIT[7] | Slant pattern |
+--------+-------------------------------+
Based on function above, current test pattern programming is wrong.
This patch fixes it by 'BIT(pattern - 1)'. If pattern is 0, driver
will disable the test pattern generation and set the pattern to 0.

In commit 7d3c7d2a2914 ("media: i2c: Add a camera sensor top level menu")
a top level menu was added for sensor drivers so that all sensor drivers
would depend on I2C and so that MEDIA_CONTROLLER, V4L2_FWNODE and
VIDEO_V4L2_SUBDEV_API would be automatically selected for all sensor
drivers.
All lens drivers must depend on I2C and VIDEO_DEV and must select
MEDIA_CONTROLLER, V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API and most already
do, but e.g. VIDEO_V4L2_SUBDEV_API is not consistenly selected.
Change the "Lens drivers" menu into a menuconfig option with
the necessary depends and selects. This ensures that these options are
depended on / selected consistently and simplifies the Kconfig snippets
for the various lens voice coil drivers.

Use regulator_bulk_* to get the array of potential power rails for
the hi556.
Previously the driver only supported avdd as only avdd is used on IPU6
designs. But other designs may also need the driver to control the other
power rails and the new INT3472 handshake support also makes use of
dvdd on IPU6 designs.

probe() requests the reset GPIO to be set to high when getting it.
Immeditately after this hi556_resume() is called and sets the GPIO low.
If the GPIO was low before requesting it this will result in the GPIO
only very briefly spiking high and the sensor not being properly reset.
The same problem also happens on back to back runtime suspend + resume.
Fix this by adding a sleep of 2 ms in hi556_resume() before setting
the GPIO low (if there is a reset GPIO).
The final sleep is kept unconditional, because if there is e.g. no reset
GPIO but a controllable clock then the sensor also needs some time after
enabling the clock.

When the EDID is updated, the hotplug detect signal must remain low for
100 ms minimum. Currently these three drivers use that exact minimum,
but some HDMI transmitters need the HPD to be low for a bit longer
before they detect that they need to read the EDID again.
Experience shows that HZ / 7 (= 143 ms) is a good value.
So change HZ / 10 to HZ / 7.

Getting / Setting the frame interval using the V4L2 subdev pad ops
get_frame_interval/set_frame_interval causes a deadlock, as the
subdev state is locked in the [1] but also in the driver itself.
In [2] it's described that the caller is responsible to acquire and
release the lock in this case. Therefore, acquiring the lock in the
driver is wrong.
Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval()
and mt9m114_ifp_set_frame_interval().

The MT9M114 sensor has an internal PLL that generates the required SYSCLK
from EXTCLK. It also has the option to bypass the PLL and use EXTCLK
directly as SYSCLK.
The current driver implementation uses a hardcoded PLL configuration that
requires a specific EXTCLK frequency. Depending on the available clocks,
it can be desirable to use a different PLL configuration or to bypass it.
The link-frequency of the output bus (Parallel or MIPI-CSI) is configured
in the device tree.
Check if EXTCLK can be used as SYSCLK to achieve this link-frequency. If
yes, bypass the PLL.
Otherwise, (as before) check if EXTCLK and the default PLL configuration
provide the required SYSCLK to achieve the link-frequency. If yes, use the
PLL. If no, throw an error.

When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
to choose a valid format. However that sets the colorspace
based on information read back from the chip, not the colour
format requested.
The result was that if you called try or set format for UYVY
when the current format was RGB3 then you would get told SRGB,
and try RGB3 when current was UYVY and you would get told
SMPTE170M.
The value programmed in the VI_REP register for the colorspace
is always set by this driver, therefore there is no need to read
back the value, and never set to REC709.
Return the colorspace based on the format set/tried instead.

The probe for the TC358743 reads the CHIPID register from
the device and compares it to the expected value of 0.
If the I2C request fails then that also returns 0, so
the driver loads thinking that the device is there.
Generally I2C communications are reliable so there is
limited need to check the return value on every transfer,
therefore only amend the one read during probe to check
for I2C errors.

2 lanes at 594MHz, or UYVY 1080P60 over 4 lanes. (RGB888
1080P60 needs 6 lanes at 594MHz).
It doesn't allow for lower resolutions to work as the FIFO
underflows.
374 is required for 1080P24 or 1080P30 UYVY over 2 lanes @
972Mbit/s, but >374 means that the FIFO underflows on 1080P50

Pull i2c updates from Wolfram Sang:
"Core updates:
- move towards using the 'fwnode' handle instead of 'of_node'
(meaning 'of_node' even gets removed from i2c_board_info)
- add support for Write Disable-aware SPD eeproms
- minor stuff (use new helpers, typo fixes)
i2c-atr (address translator) updates:
- support per-channel alias pools
- added support for dynamic address translation (also adds FPC202
driver as its user)
- add 'static' and 'passthrough' flags
Cleanups and refactorings
- Many drivers switched to dev_err_probe()
- Generic cleanups applied to designware, iproc, ismt, mlxbf,
npcm7xx, qcom-geni, pasemi, and thunderx
- davinci: declare I2C mangling support among I2C features
- designware: clean up DTS handling
- designware: fix PM runtime on driver unregister
- imx: improve error logging during probe
- lpc2k: improve checks in probe error path
- xgene-slimpro: improve PCC shared memory handling
- pasemi: improve error handling in reset, smbus clear, timeouts
- tegra: validate buffer length during transfers
- wmt: convert binding to YAML format
Improvements and extended support:
- microchip-core: add SMBus support
- mlxbf: add support for repeated start in block transfers
- mlxbf: improve timer configuration
- npcm: attempt clock toggle recovery before failing init
- octeon: add support for block mode operations
- pasemi: add support for unjam device feature
- riic: add support for bus recovery
New device support:
- MediaTek Dimensity 1200 (MT6893)
- Sophgo SG2044
- Renesas RZ/V2N (R9A09G056)
- Rockchip RK3528
- AMD ISP (new driver)"

Some I2C ATRs do not support dynamic remapping, only static mapping
of direct children.
Mappings will only be added or removed as a result of devices being
added or removed from a child bus.
The ATR pool will have to be big enough to accommodate all devices
expected to be added to the child buses.
Add a new flag that prevents old mappings to be replaced or new mappings
to be created in the alias finding code paths. That mens adding a flags
parameter to i2c_atr_new() and an i2c_atr_flags enum.

The ov02c10 driver divides a 64-bit number but reply relies on division
operator to do that. Use div_u64() so this will compile everywhere.
