This compatible makes no sense, we shouldn't be marking a full HW block with some name that is just intended for LIODN convenance. Is this version 3 of the block? If so a name like "fsl,maple-v3" or "fsl,maple-v3.0" would be more appropriate. - k

Does Maple not have any IRQs associated with it? If you are going to have a minimal binding, at least cover the basics associated with a device.
