    SubjectRE: [PATCHv2 1/2] ARM: mx51: Implement code to allow mx51 to enter WFI
    Date
    Hi Arnaud,

    Just to verify that you are testing on an MX51-Babbage board? Here's my log:

    root@freescale ~$ uname -a
    Linux freescale 2.6.38-rc1+ #93 Fri Mar 4 17:18:15 CST 2011 armv7l GNU/Linux
    root@freescale ~$ echo mem > /sys/power/state
    PM: Syncing filesystems ... done.
    Freezing user space processes ... (elapsed 0.01 seconds) done.
    Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
    Suspending console(s) (use no_console_suspend to debug)

    <Press power key here, and the wake up is the bottom>.

    PM: suspend of devices complete after 0.835 msecs
    PM: suspend devices took 0.000 seconds
    PM: late suspend of devices complete after 0.159 msecs
    PM: early resume of devices complete after 0.187 msecs
    PM: resume of devices complete after 81.911 msecs
    PM: resume devices took 0.090 seconds
    Restarting tasks ... done.
    root@freescale ~$


    Thanks,

    Dinh
