Add support for CN0556

[AndyOesmer]

Description

++ Adding support for CN0556

• Added cn0556.py in library

• Added cn0556 examples (Buck Mode Example and Boost Mode Example)

• Added cn0556 production test scripts

• Added pytest for cn0556

• New feature (non-breaking change which adds functionality)

How has this been tested?

The example scripts were run by using interfacing the EVAL-CN0556-EBZ with an EVAL-CN0554-RPIZ and a Raspberry Pi 4 connection. The SD card of the Raspberry Pi 4 is flashed with the ADI Kuiper Linux image. The device tree overlay must be configured to identify the CN0556 connected to it.

Test Configuration:

• Hardware: EVAL-CN0556-EBZ + EVAL-CN0554-RPIZ + Raspberry Pi 4 with ADI Kuiper Linux Image
• OS: pyadi-iio examples can be run directly from Raspberry Pi GUI or by accessing remotely thru LAN
