This driver is based on the one for NPCM7xx, because the WPCM450 is a
predecessor of those SoCs. Notable differences:
- On WPCM450, the GPIO registers are not organized in multiple banks,
but rather placed continually into the same register block. This
affects how register offsets are computed.
- Pinmux nodes can explicitly select GPIO mode, whereas in the npcm7xx
driver, this happens automatically when a GPIO is requested.
Some functionality implemented in the hardware was (for now) left unused
in the driver, specifically blinking and pull-up/down.

This binding is heavily based on the one for NPCM7xx, because the
hardware is similar. There are some notable differences, however:
- The addresses of GPIO banks are not physical addresses but simple
indices (0 to 7), because the GPIO registers are not laid out in
convenient blocks.
- Pinmux settings can explicitly specify that the GPIO mode is used.
Certain pins support blink patterns in hardware. This is currently not
modelled in the DT binding.
