The physical address returned by __pa is higher than the maximum physical memory I have on the board. This result make my driver hang. The driver I'm trying to use was written for a 2.4 kernel and I'm wondering if I have to replace the calls to __pa with some other API/MACRO.

If you're calling it on an ioremapped address, that won't work.
Those come out of vmalloc space.

Just store the physical address somewhere if you really need it.
