From: Matthias Weisser Date: Mon, 24 Sep 2012 02:46:53 +0000 (+0000) Subject: imx: Use MXC_I2C_CLK in imx i2c driver X-Git-Tag: v2013.01-rc1~209 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e7bed5c2b30c894666e43b68a3d7b8e8f91da50d;p=oweals%2Fu-boot.git imx: Use MXC_I2C_CLK in imx i2c driver i2c didn't work on imx25 due to missing MXC_IPG_PERCLK. Now using MXC_I2C_CLK on all imx systems using i2c.
