The name of I2C controller over GPIO lines node ends with '-gpio' which
confuses dtschema:

  /arch/arm/boot/dts/exynos4210-i9100.dt.yaml: /: i2c-gpio:
    {'compatible': ['i2c-gpio'], ...  'maxim,over-volt': [[4500]]}} is not of type 'array'
    From schema: lib/python3.6/site-packages/dtschema/schemas/gpio/gpio-consumer.yaml

Add a '-0' suffix to silence it.  This pattern on naming i2c-gpio is
already present in many other dts.  No functional change.

The regulator property 'regulator-microvolt-offset' should be put next
to regulator definition, not consumer.

The property 'regulator-microsecs-delay' is not valid at all.

The S3C RTC requires 32768 Hz clock as input which is provided by PMIC
(Maxim MAX8997).  However there is no clock provided for the PMIC and
the driver registers the clock as regulator.  This is an old driver
which will not be updated so add a workaround:
1. Enable the "clock" regulator in PMIC,
2. Add a fixed-clock to fill missing clock phandle reference in S3C RTC.

This allows to enable the S3C RTC and fixes dtbs_check warnings:

  arch/arm/boot/dts/exynos4210-i9100.dt.yaml: rtc@10070000: clocks: [[5, 346]] is too short
  arch/arm/boot/dts/exynos4210-i9100.dt.yaml: rtc@10070000: clock-names: ['rtc'] is too short

The PMIC has a 32768 Hz clock used by the modem which is implemented by
driver as a regulator.  Add and enable it to be sure modem get's its
signal.

The PMIC has a 32768 Hz clock used by the modem which is implemented by
driver as a regulator.  Add and enable it to be sure modem get's its
signal.

The camera's pinctrl configuration is simply empty and not effective.
Remove it to fix dtbs_check warning:

Using full paths to extend or override a device tree node is error prone
since if there was a typo error, a new node will be created instead of
extending the node as it was desired.  This will lead to run-time errors
that could be hard to detect.

A mistyped label on the other hand, will cause a dtc compile error
(during build time).

Using full paths to extend or override a device tree node is error prone
since if there was a typo error, a new node will be created instead of
extending the node as it was desired.  This will lead to run-time errors
that could be hard to detect.

A mistyped label on the other hand, will cause a dtc compile error
(during build time).

Add node for clock controller of Samsung S5M8767 PMIC.  This provides
the 32768 Hz clock required by S3C RTC.  Except making the S3C RTC
working, this also fixes dtbs_check warnings:

Using full paths to extend or override a device tree node is error prone
since if there was a typo error, a new node will be created instead of
extending the node as it was desired.  This will lead to run-time errors
that could be hard to detect.

A mistyped label on the other hand, will cause a dtc compile error
(during build time).

Add missing cooling devices for CPU thermal zones in Exynos4412 Origen
board.  This allows to scale down CPU frequency (and voltage) in case of
thermal pressure.

The S3C RTC requires 32768 Hz clock as input which is provided by PMIC.
However the PMIC is not described in DTS at all so at least add a
workaround to model its clock with fixed-clock and silence dtbs_check
warnings like:

  arch/arm/boot/dts/exynos4412-smdk4412.dt.yaml: rtc@10070000: clocks: [[7, 346]] is too short
  arch/arm/boot/dts/exynos4412-smdk4412.dt.yaml: rtc@10070000: clock-names: ['rtc'] is too short

I think that this was intentional to properly enable support for 
mem-2-mem mode in Exynos4-IS (FIMC), but I'm not sure what are the 
default values if no pinctrl properties are provided. Sylwester, could 
you comment?

Indeed it could be intentional... I see now errors:
[   33.752203] s5p-fimc-md soc:camera: Failed to get pinctrl: -19

I wonder why getting an empty pinctrl is needed... maybe the driver
should accept missing pinctrl?

Best regards,
Krzysztof

Origen board doesn't have any modem/cp, so I see no point in enabling 
this clock.

It might have been better to have the pinctrl properties optional, as there
might be boards without the image sensor attached and FIMC could still be 
used in memory-to-memory mode, as Marek pointed out. But it seems too late 
now to change that. The binding defines the pinctrl properties as required 
(Documentation/devicetree/bindings/media/samsung-fimc.txt) and we need to
keep them in dtses.

You can always make a required property optional and it is not a break
of ABI. The other way around would be a break. Why then not changing
the driver to accept optional pinctrl?

Feel free to send the patch, I would prefer to leave that as is though.
Is it really suddenly a problem to use an empty property? The pinctrl 
bindings allows it.

The bindings scream:
arch/arm/boot/dts/exynos4412-odroidx.dt.yaml: camera: pinctrl-0: True
is not of type 'array'
so either we should model it differently (not as empty array), update
the driver to make it optional or change the bindings/dtschema. I'll
see how to fix it properly.
