GPU cooling isn't really to do with GPU power management, it's more
to do

I don't have any input on this binary divider subject but I do want to
bring up some observations regarding Etnaviv GPU power management that
seems relevant.
I've done some comparisons between the Freescale Vivante GPU driver
stack (1) and the Marvell PXA1928 Vivante GPU driver stack (2) and see
