Nothing uses any of the clock stuff; I don't think we should add this
until it's needed.

Similarly, nothing uses this.

This needs the following extra line here:
interrupts = <0 36 0x04>;

Although again, nothing uses this, so may as well omit it.

May as well leave that out until it's needed.

There's an indentation error there.
