Documentation howto add a new device, only the Slave Port and GPIO-scanner

Documentation howto add a new device.
Only the Slave Port and GPIO-scanner part.
This give advanced users extra tools to add a new device and find all the gpio and settings.

Todo:

• Add link in the Readme
• How to find the EEPROM spot
• GPIO-scanner script via Slave Port.
• Python script to dump register settings via stock-firmware via rd-command
• Tell about the pull-up
• Tell a bit more about the i2c-tools

For me this looks already great. Could you also add a change that places it prominently on the main page with an explanation that this can help to support new devices?

Will do.
I added a todo-list, so I know what to write.

Looks great, maybe three things to add:

• SDA and SCL will be probably on logic high
• One can run ic2detect and should see 0x5c in active devices
• Use ic2detect -l to list I2C buses, you probably have more than one

For the gpio scanner documentation, it would be helpful to document how to translate the output to gpio pin numbers.
