Subject: regulator: da9055: Pass descriptor instead of GPIO number
X-Git-Tag: v5.15~9155^2^5~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8d05560d1d011e5a842556efdbd70cc8a21499bb;p=platform%2Fkernel%2Flinux-starfive.git

regulator: da9055: Pass descriptor instead of GPIO number

When setting up a fixed regulator on the DA9055, pass a descriptor
instead of a global GPIO number. This facility is not used in the
kernel so we can easily just say that this should be a descriptor
if/when put to use.
