[PATCH v1 07/19] arm: dts: mt7623: fix the regulators mmc should use on bananapi-r2

From: sean.wang
Date: Fri Feb 23 2018 - 05:21:00 EST


From: Sean Wang <sean.wang@xxxxxxxxxxxx>

Both mmc devices on bananapi-r2 board should all use the fixed regulators
as their power source instead of PMIC MT6323 exports.
