# This is a BitKeeper generated diff -Nru style patch. # # ChangeSet # 2004/09/14 12:30:28+02:00 tnt@246tNt.com # ppc: Allow the Freescale MPC52xx to NAP when idle on LITE5200 platform # # NAP allows some powersave. It's provided mainly as an example on how to do it. # However, when a BDI is plugged it causes early crashes so be aware ! # # Signed-off-by: Sylvain Munaut <tnt@246tNt.com> # # arch/ppc/platforms/lite5200.c # 2004/09/14 12:30:11+02:00 tnt@246tNt.com +7 -0 # ppc: Allow the Freescale MPC52xx to NAP when idle on LITE5200 platform # diff -Nru a/arch/ppc/platforms/lite5200.c b/arch/ppc/platforms/lite5200.c --- a/arch/ppc/platforms/lite5200.c 2004-09-14 12:48:13 +02:00 +++ b/arch/ppc/platforms/lite5200.c 2004-09-14 12:48:13 +02:00 @@ -36,6 +36,8 @@ #include <asm/mpc52xx.h>
