[v7] Add I2C support for Tegra410

[PATCH v7 0/4] Add I2C support for Tegra410

Posted by Kartik Rajput 3 weeks, 4 days ago

Add support for the Tegra410 SoC, which has 4 I2C controllers. The
controllers are feature-equivalent to Tegra264; only the register
offsets differ.

Kartik Rajput (4):
  i2c: tegra: Introduce tegra_i2c_variant to identify DVC and VI
  i2c: tegra: Move variant to tegra_i2c_hw_feature
  i2c: tegra: Add logic to support different register offsets
  i2c: tegra: Add support for Tegra410

I had a comment on patch 3/4. There is a V8 now, but the commit message 
is still not quite right. Although I am happy with V8 in general. We can 
do one more quick spin and then I am happy to ACK.
