    ARM: OMAP: Fix i2c init for twl4030 · bfd46a54

    Looks like 2600 kHz rate does not work reliably on 2430,
    so just use the 100 kHz rate.
    
    Otherwise the system often fails to boot properly with:
    
    omap_i2c omap_i2c.2: timeout waiting for bus ready
    omap_i2c omap_i2c.2: timeout waiting for bus ready
    twl: i2c_write failed to transfer all messages
    omap_i2c omap_i2c.2: timeout waiting for bus ready
    twl: i2c_write failed to transfer all messages
    omap_i2c omap_i2c.2: timeout waiting for bus ready
    twl: i2c_write failed to transfer all messages
    twl: clock init err [-110]
    omap_i2c omap_i2c.2: timeout waiting for bus ready
    twl: i2c_write failed to transfer all messages
    TWL4030 Unable to unlock IDCODE registers --110
