Subject: [PATCH v2] ARM: mxs: Select ARM_CPU_SUSPEND
Date: Wed, 6 Feb 2013 23:47:25 -0200 [thread overview]
Message-ID: <1360201645-2456-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@freescale.com>
Select ARM_CPU_SUSPEND so that suspend/resume can be tested on mxs platforms.
Tested on a mx28evk board:
$ echo enabled > /sys/devices/80000000.apb/80040000.apbx/80074000.serial/tty/ttyAMA0/power/wakeup
$ echo mem > /sys/power/state
[ 507.040000] PM: Syncing filesystems ... done.
[ 507.060000] mmc0: card e624 removed
[ 507.160000] Freezing user space processes ... (elapsed 0.01 seconds) done.
[ 507.180000] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
[ 507.200000] Suspending console(s) (use no_console_suspend to debug)
(Then send any character via DUART to wakeup the system).

Changes since v1:
- Replace AUART with DUART, since ttyAMA0 is the debug UART.
