Sorry for the long delay. I tried to analyze the issue. Attached patch works
on AC100 (Misha Komarovsky helped me with testing).
Wolfram could you please try the patch with your environment?
No change, sadly. I don't get slave interr
hanks.

Subject: [PATCH] i2c: tegra: don't reset I2C slave address on init
Init function is called multuple times. If I2C controller works

Still doesn't work for me and I think I understand why. Do you run your
I2C controller in slave mode only?
Yes.
That might work, but using it in
master/slave mode simultanously won't work yet as I see it:

I think in this case it would be better to leave nvec and dt as it is for now,

This version (v3) is for pushing tegra i2c driver to i2c tree.
NVEC driver will be reworked later to use i2c core slave framework.
NVEC driver contains code to manage tegra i2c controller in slave mode.
I2C slave support was implemented in linux kernel

Initialization code is based on NVEC driver.
There is a HW bug in AP20 that was also mentioned in kernel sources
for Toshiba AC100.
