This property is required.

drive-strength

string

Used to configure the pad's drive strength, which, together
with the slew rate, affects the maximum frequency the pad's
output buffer can yield. If "normal" drive strength is used,
the maximum frequency will be lower as per the measurements
found in the SoC datasheet. Note that the TRM refers to the
"normal" drive strength as "standard". If unspecified, the
default will be "normal".

Legal values: 'normal', 'high'

slew-rate

string

Used to configure the pad's slew rate, which affects the
maximum frequency the pad's output buffer can yield (
"fast" slew rate -> higher pad frequency, "slow" slew rate ->
lower pad frequency). Note that the TRM refers to the "fast"
slew rate as "standard". If unspecified, the default will be
"fast".

Legal values: 'fast', 'slow'
