Re: [PATCH 5/9] arm: mvebu: theadorable: Switch to using DM I2C API

No functional change intended. This patch switches from the legacy I2C API to the DM I2C API, so that this code can be used with DM I2C enabled.

Signed-off-by: Stefan Roese sr@denx.de

Applied to u-boot-marvell/next

Thanks, Stefan
