From 8d91771ca4aff257f53ac7643f90b5cbb740971b Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 17 Apr 2012 10:15:54 +0200 Subject: [PATCH] gpio/nomadik: use ioremap() instead of static mappings We were using a custom io_p2v() (physical-to-virtual) translation macro, but it's fully possible to just ioremap() this memory now, so skip use of static addresses altogether.
