Cover letter [PATCH 0/3] XRA1403,gpio - add XRA1403 gpio expander driver
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.
