PS13, Line 12: The purpose of this device is not clear
> We might want to wait for chipset devicetrees to allow configuring the device through Kconfig. […]

If we want the dt to specify the default, we could add a Kconfig like this:

~~~
choice
 prompt "Override devicetree: CHAP"
 default DT_CHAP_NO_OVERRIDE

config DT_CHAP_NO_OVERRIDE
 bool "use devicetree value"

config DT_CHAP_ENABLE
 bool "enable"

config DT_CHAP_DISABLE
 bool "disable"

endchoice
~~~
