Hi,
thanks for the advice, I have found the bad commit,
it is -> 02cc27c74f9b884b538bcd1b93342a4c05b5d608
sunxi: power: Change axp209 LDO3 and LDO4 default to disabled
after that I tried the v2016.01 release again, but changed
the two lines in config AXP_ALDO3_VOLT and config AXP_ALDO4_VOLT
back to their old values, now the SATA Port is working again.
Thanks for debugging this, according to the Bananapro schematic
VDD25-SATA either comes from a dedicated WL2003E25-5 linear regulator,
or it is connected to LDO4 via a 0 Ohm resistor.
So it would seem that in practice it seems that LDO4 is used, can you
give the attached patch a try ?
I had access to a bananapro board myself today, and I can confirm that
the patch I wrote fixes this.
Regards,
Hans
