Whem trying to add a gpio hog to enable the USB Hub on the Odroid-C2, I encountered a strange bug where when calling gpiochip_add_data() the gpiolib code was trying to add the Hog but failed because the gpio ranges were missing. In the meson-pinctrl driver, the gpio ranges are added manually /after/ the call to gpiochip_add_data(). The arch/arm meson8 and meson8b patches has not been tested, this is why this patchset is an RFT. So this patchset uses the DT gpio-ranges attribute instead and solves the issue. The final patch is the actual GPIO Hog for the Odroid-C2 board, which is an ugly hack but is necessary to have USB Ports working on the board until the generic power sequence framework is merged.
