Subject: power: regulator: update comments for regulator-name
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=40ade2ce58ed57fe1bff20265b3e015710ff862e;p=u-boot.git

power: regulator: update comments for regulator-name

We do not need that "regulator-name" property must be provided in dts.
If "regulator-name" property is not provided in dts, node name
will chosen for settings '.name' field of uc_pdata.
