DM: OMAP24XX_I2C: Reduce overhead when used with OF_PLATDATA
Platforms with limited resources in SPL may enably OF_PLATDATA, this limits some of the library functions and cannot extract data from the device tree. This patch adds additional wrappers around these functions to only allow them when OF_CONTROL is enabled and OF_PLATDATA is not. Signed-off-by: Adam Ford <aford173@gmail.com>
