[PATCH v4 2/2] ARM: EXYNOS: Remove i2c sys configuration related code
From: Pankaj Dubey <hidden>
Date: 2014-10-30 08:04:30
Also in:
linux-samsung-soc
Subsystem:
arm port, cpuidle driver - arm exynos, the rest · Maintainers:
Russell King, Daniel Lezcano, Kukjin Kim, Linus Torvalds
As all these code has been moved into i2c driver, now we can safely remove them from machine files.
