Pi4J 2.5 multiple I/O providers

[tatery]

Hi,
Providers description says:
"As of Pi4J 2.5 multiple providers for the same I/O type is no longer supported. During the Context initialization it will ensure only a single provider for an I/O type is loaded." (https://pi4j.com/documentation/providers/)

I'm using the built-in RaspberryPi I/O (with PiGpio provider) and the I/O extension MCP23017 (along with a custom GPIO provider: https://github.com/savageautomate/pi4j-plugin-microchip).

Is it possible to use both providers at the same time in Pi4J version 2.5?

@eitch Can you read over this question? With provider priority implementation it seems this provider must be a new IO type. Your thoughts

At the moment it isn't possible. This is a use-case i didn't see. We'll have to think about this. Currently we've done this differently, e.g. @taartspi has a MCP23017 implementation here:
