The idea is that if COMPILE_TEST is off you can only enable the driver
for machines where the device in question really exists to simplify
kernel configuration. Sometimes this isn't really possible, e.g. for i2c
devices that can be put on more or less every machine. I had the
impression that the cadence i2c bus device only exists on Zync? Ok, you
could implement this device on every SoC that has some programmable
hardware, but that is not the point.

Best regards
Uwe
