Add a new driver to create a device named /dev/iomux, which allows userland to set or get iomux by bank index and pin index. For now the /dev/iomux supports two commands: - IOMUX_IOC_MUX_SET - IOMUX_IOC_MUX_GET Signed-off-by: Jianqun Xu <jay.xu@rock-chips.com> Change-Id: I0467af6885863f5dc69d513601f597fca2cc6948
