This patch series adds error handling for the PHY read/write path and optional
register access validation.
After adding regmap_ranges for KSZ8563 some bugs was detected, so
critical bug fixes are sorted before ragmap_range patch.

Potentially this bug fixes can be ported to stable kernels, but need to be
reworked.
