Hi Yinbo, thanks for your patch!

Then you have added this to reimplement gpio ranges. It also shows in the driver. Drop gpio_base altogether (we do not encode linux-specific properties into the device trees) and use gpio-ranges as they are intended to map between the GPIO numberspace and the pin control pin number space. See Documentation/devicetree/bindings/gpio/gpio.txt for documentation on gpio-ranges, also look how other drivers are using them. Yours, Linus Walleij
