Subject: ARM: ux500: fix up the I2C devices
X-Git-Tag: next-20130912~99^2~10^2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1e66a3da4f7d73c027200fb18bb452fbde17fbd7;p=karo-tx-linux.git

ARM: ux500: fix up the I2C devices

The I2C device registration on the different ux500 board was
buggy due to a switch to dynamically assigned I2C host
addresses. This I2C host is still there, but we have to add
the devices dynamically instead of using board data.
