Banan Pro (ahci-sunxi) SATA port stopped working after switching to U-Boot v2016.01

Quoted 19 lines

Hello,

tonight I switched to the new U-Boot v2016.01 on my Banana Pro system.
I compiled u-boot, like I did with all the working versions before, with:
make Bananapro_defconfig
make

But with the new U-Boot installed the SATA Port did not work anymore.
The Kernel is the same 4.0.9-gentoo as I used before with the last U-Boot Release v2015.10

dmesg show me the following error in the kernel log:

[    1.925032] ahci-sunxi 1c18000.sata: PHY power up failed.
[    1.930661] ahci-sunxi: probe of 1c18000.sata failed with error -5

Quoted 3 lines

I also see now SATA message at the U-Boot bootscreen, the v2015.10 shows me that a SATA Port was recognized by the U-Boot loader.

Can you please use git bisect to determine which commit broke this? Thanks!

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 ?
