From 6b625891c6b541080bdaad97bcb82bd9ecd9e44b Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Wed, 16 Oct 2013 16:24:57 +0200 Subject: [PATCH] ARM: AT91: DT: pm: Select ram controller standby based on DT Move non-dt selection to ioremap_registers init which is only called not non-dt board. So we can support sam9n12/sam9x5/sama5d3 too.
