The big complaint from v1 was that too much unnecessary data was being pushed into devicetree. v2 takes a different approach of using just compatbile strings for the heaps. This gets closer to the devicetree philosophy of describing just the hardware. Each heap ultimately represents some kind of memory that exists in the system. The compatible string indicates the match for how to handle the type of memory on this system. The details like heap-id, name etc. are now pushed out to C files. This makes Ion heaps look closer to something like a quirks framework. (I'd argue this isn't a complete mischaracterization given the type of setup Ion gets used for...) The one downside here is that this leads to more new bindings for each board that gets added. This version also includes a sample C file which shows what the structure might look like. As always, your comments and reviews are appreciated.
