From b59160f6c017bfe33d3483ed9a6120701644af8a Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Wed, 25 Jan 2012 00:56:07 +0100 Subject: [PATCH] ARM: at91: remove wait_for_interrupt definition All the "wait_for_interrupt" definition are aliases to cpu_do_idle. Only the rm9200 has an asm routine to switch to wfi. But the cpu_do_idle for this platform has exactly the same asm routine. arch/arm/mm/proc-arm920.S .. ENTRY(cpu_arm920_do_idle) mcr p15, 0, r0, c7, c0, 4 @ Wait for interrupt .. Then it is safe to invoke cpu_do_idle for this platform. As all the wait_for_interrupts are definition for cpu_do_idle, let's remove it and replace its invokation by cpu_do_idle.
