I guess it is because at the moment nothing select REGMAP_W1 in
mainline. I did not (yet) queue the power-supply driver, which
was the initial reason for adding regmap w1 support.

FWIW I am just the messenger, who actually pointed out the issue
_before_ it happened in the threads of both patchsets. I expected
this to be properly solved by you and Greg. Since this did not
work out regmap seems now the logical subsystem for the fix.
