Commit 52005dece527 ("ARM: dts: Add assigned clock parents to CMU node
for exynos3250") added assigned clocks under Clock Management Unit to
fix hangs when accessing ISP registers.
This is not the place for it as CMU does not have a required "clocks"
property:
arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml: clock-controller@10030000: 'clocks' is a dependency of 'assigned-clocks'
Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

Not tested and I wonder whether actually correct. For example, what will
happen if devfreq (exynos-bus) is not built in?
Could someone verify it?
