@ -18,9 +18,8 @@ Required properties:
- pinctrl-names: Must contain a "default" entry.
- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
See ../pinctrl/pinctrl-bindings.txt for details of the property values.
- big-endian-regs: If this property is absent, the little endian mode will
be in use as default, or the big endian mode will be in use for all the
device registers.
- big-endian: Boolean property, required if all the FTM_PWM registers
are big-endian rather than little-endian.
- big-endian-data: If this property is absent, the little endian mode will
be in use as default, or the big endian mode will be in use for all the
fifo data.
