Not true. This board is not manufactured by Freescale, so you should
not use the 'fsl,' prefix. Use your companies name or stock ticker
symbol instead.

This doesn't look right. The local bus is not board specific; it is
SoC specific. So this should be:
compatible = "fsl,mpc5121-localbus", "simple-bus";

Drop this device_type property

should be: compatible = "fsl,mpc5121-i2c", "fsl-i2c";

This doesn't look right. Correct format is: compatible = "fsl,5121-i2c-ctrl";

This doesn't look right either, "fsl-diu" is the wrong format, but you
many not be able to do anything about that. At the very least, this
one should be: compatible = "fsl,mpc5121-diu", "fsl-diu";

Again, need the mpc5121 specific value before the common one.

If it is not being used, then I would drop this node entirely (but
that is personal preference). If you keep it, fix the compatible
value.

Looks like you've just duplicated mpc5121_ads.c. You should just add
your boards name to the mpc5121_ads_probe function. Bonus points if
you rename the .c file to something more generic. You only need a new
board file if your board needs something special.
Cheers,
g.
