and operational. This is useful on systems where the bus voltage level
translator is optional, as the translator can be auto-detected by the
driver and the feedback clock functionality can be disabled if it is
not present.
The translator test sets CMD high to avoid interfering with a card, and
then verifies whether signal set on CK is detected on CKIN. If the signal
is detected, translator is present, otherwise the CKIN feedback clock are
disabled.

ARM: dts: stm32: Add custom PHY reset bindings on AV96
The ethernet PHY must be reset on AV96, however DWMAC currently does
not support the MDIO-bus PHY GPIO reset bindings and the ethernet MAC
PHY reset property is going away on next DT sync. Add PHY specific
reset bindings to trigger the PHY reset and fix sporadic ethernet
malfunctions, until the next DT sync.

The variables retaining the strap values have to be initialized, always,
make it so. Moreover, free the requested GPIO list at the end to avoid
wasting memory.
