Subject: mfd: dt-bindings: mt6397: Add regulator supplies
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7502c035b884b73f51669cada3f4022cd11e8f5c;p=thirdparty%2Fkernel%2Flinux.git

mfd: dt-bindings: mt6397: Add regulator supplies

On the MT6397 family each buck regulator has a separate supply. LDOs are
split into various groups with independent supplies. There is also a
supply for the regulator control logic.

Add descriptions for all of the supplies for the MT6359.
