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 Signed-off-by: Philipp Rossak <embed3d@gmail.com> --- arch/arm/boot/dts/sun6i-a31s-sinovoip-bpi-m2.dts | 56 ++++++++++++++++++++++++ 1 file changed, 56 insertions(+)
