Patches for clocks drivers change the way the clock provider is initialized.
Instead of CLK_OF_DECLARE based initialization, a complete platform device driver
infrastructure is being used. This is needed to let driver to use runtime PM
feature and integrate with generic power domains. The side-effect of this change
is a delay in clock provider registeration during system boot, so early
initialized drivers might get EPROBEDEFER error when requesting their clocks.
This was an issue for IOMMU drivers, but IOMMU deferred probe support has been
finally merged to v4.13-rc1 and now it is handled correctly.
Any chances you have PHY devices falling back to polling due to this,
cfr. https://patchwork.kernel.org/patch/9734175/?
At least in case of Exynos5433 all related PHY drivers correctly handle
deferred
probe and don't fallback to half-functional mode.
