Hello all,
I'm running Debian Jessie with Linux 4.3.0-0.bpo.1-armmp-lpae on my a20-olinuxino-lime2. I have noticed that my board hangs with my recent u-boot versions when I load the i2c module.
git-bisect narrowed the problem down to the following commit:
02cc27c74f9b884b538bcd1b93342a4c05b5d608 is the first bad commit commit 02cc27c74f9b884b538bcd1b93342a4c05b5d608 Author: Hans de Goede hdegoede@redhat.com Date: Sat Oct 3 15:29:24 2015 +0200
sunxi: power: Change axp209 LDO3 and LDO4 default to disabled
LDO3 and LDO4 are normally either unused, or used to power csi attached camera sensors, and as such do not need to be enabled at boot time.

The axp209 is attached to the i2c bus, so that is likely the real culprit. In my setup, the axp209 drivers are loaded before I insert i2c-mv64xxx.
What would be the best course of action here?
* Revert the commit * Enable LDO3 and LDO4 for the a20-olinuxino-lime2 only? * Fix linux
Best,
Michael
