[U-Boot] [PATCH v2 0/9] arm:exynos4: Enable Multi I2C

[Piotr Wilczek]

This patchset enables both software and hardware I2C support for Exynos 4.
New multi_i2c driver is added to support simultaneous use of hardware
and software I2C drivers.
The s3c24x0_i2c driver is modified to use for for both Exynos 4 and Exynos 5.
Both s3c24x0_i2c and soft_i2c drivers are modified so can be used separetly
(only hardware or only software) or can be used simultaneously.
Pinmux setting and clock is add for Exynos4 to support hardware I2C.

This patchset depends on the following patchset:
