Subject: mfd: twl-core: Register twl4030-madc child only for twl4030 class
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=24ae36f5c285d14f449dd19821aca1097a2a2313;p=deliverable%2Flinux.git

mfd: twl-core: Register twl4030-madc child only for twl4030 class

twl4030-madc driver can only handle twl4030 class MADC. The newer revisions
of twl does not have MADC, instead they have different IP called GPADC which
is not backward compatible.
