This patchseries fixes the bananapi m1 devicetree, to be able to boot again.
The first two patches update/improve the devicetree and the last patch adds
all missing regulators.

The eldoin is supplied from the dcdc1 regulator. The N_VBUSEN pin is
connected to an external power regulator (SY6280AAC).
With this commit we update the pmic binding properties to support
those features.

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 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.

Thanks
Hey Sergey,
Thanks for mentioning, but I think the problem has nothing to do with
those patches. I tested them with the v4.15.0 Kernel since this is the
last stable release and we are right now in the merging window.
I tested the latest mainline, without those patches and the kernel is
not booting (I can't see any uart output).
Thanks,
Philipp

Can you please share a bootlog? Here is mine [1]. As you can see I'm
able to boot.
I build it with this branch [2]. For testing you should replace the dtb
and the uImage/zImage

My dmesg is very similar to yours unless it hangs on the last line [1].
For this test I used kernel from tag v4.15 with no additional patching.

For me it looks like you have a different kernel and also an different
dtb that you patch! And you are applying also a fixup script.
These patches should be applied on top of linux mainline.
fixup script:
Applying kernel provided DT fixup script (sun6i-a31s-fixup.scr)
Linux versions:
4.15.0-00003-g1bbe5edde691 vs 4.15.0-sunxi-dirty
In addition to that you are also booting into fb/hdmi.
If you use my branch (uImage and dtb) and replace the current boot.cmd
with this (to get the boot.scr you need to use mkimage) it should work:
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait
panic=10
load mmc 0:1 0x43000000 ${fdtfile} || load mmc 0:1 0x43000000
boot/${fdtfile}
load mmc 0:1 0x42000000 uImage || load mmc 0:1 0x42000000 boot/uImage
bootm 0x42000000 - 0x43000000
