Thought you'd ask :) Exynos850 has both I2C and HSI2C blocks:
- I2C is a regular I2C, and uses s3c2410-i2c driver
- whilst HSI2C is a high-speed I2C (used for example for cameras),
and uses exynos5-hsi2c driver

I'll look into HSI2C enablement on Exynos850 soon as well, so Jaewon's
patches might be helpful for my case too -- didn't check that yet.
