From 2eaa03b5bebd1e80014f780d7bf27c3e66daefd6 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 22 Apr 2011 22:03:11 +0200 Subject: ARM / PXA: Use struct syscore_ops for "core" power management Replace sysdev classes and struct sys_device objects used for "core" power management by the PXA platform code with struct syscore_ops objects that are simpler. This reduces the code size and the kernel memory footprint. It also is necessary for removing sysdevs entirely from the kernel in the future. Signed-off-by: Rafael J.
