From: Philipp Rossak embed3d@gmail.com

commit 70b8d21496758dd7ff600ec9de0ee3812fac7a40 upstream.

This patch fixes a bootproblem with the Bananapi M2 board. Since there are some regulators missing we add them right now. Those values come from the schematic, below you can find a small overview:

* reg_aldo1: 3,3V, powers the wifi * reg_aldo2: 2,5V, powers the IO of the RTL8211E * reg_aldo3: 3,3V, powers the audio

* reg_dldo1: 3,0V, powers the RTL8211E * reg_dldo2: 2,8V, powers the analog part of the csi * reg_dldo3: 3,3V, powers misc * reg_eldo1: 1,8V, powers the csi * reg_ldo_io1:1,8V, powers the gpio

* reg_dc5ldo: needs to be always on

This patch updates also the vmmc-supply properties on the mmc0 and mmc2 node to use the allready existent regulators. We can now remove the sunxi-common-regulators.dtsi include since we don't need it anymore.
