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.
