The patchset will add a driver to support basic functionality for XRA1403 device. Features supported: - configure gpin as input/out - get/set gpio status Documentation: A gpio-xra1403.txt file was added to document the DTS bindings related to driver. Testing: 1. XRA1403 connected to iMX53 MCU 2. Export gpio from userspace 3. Verify that corresponding gpio directories are created in `/sys/class/gpio/gpioXX` 4. Export gpios from first and second bank as output 5. Set the output gpio pin to high/low and verify with the oscilloscope that gpio status is according with the configured value.
