This patch is an RFC based on recent discussions. It's only lightly
tested. I have yet to verify that the registers are being set correctly.
I'm sending it out now because I have to leave for today.

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:

You can dump these with 'mii read' in u-boot. I sat down with the

Hello all,
I'd like to add some device-specific hacks to realtek.c. I'm using the
Olimex A20-OlinuXino-Lime2 which uses the RTL8211CL PHY.
Which of the various phy_driver structs is responsible for that device?
I presume it's keyed off the .uid, but I'm not sure how to find the ID

Hello all,
After the board locked up, I am now working exclusively from within

appear to work well but the kernel won't boot. And sometimes,
downloading a kernel will just time-out.
A reset is often enough to get a behavior chan
