From 95b8e195427ce0c6b495925813d7e10949af8ce3 Mon Sep 17 00:00:00 2001
From: Andy Green <andy@openmoko.com>

Subject: [PATCH] add-resume-reason-sysfs.patch

If you have U-Boot with uboot-add-find-wake-reason.patch, this
patch will get you a wake reason report from

cat /sys/devices/platform/neo1973-resume.0/resume_reason

it looks like this:

  EINT00_ACCEL1
  EINT01_GSM
  EINT02_BLUETOOTH
  EINT03_DEBUGBRD
  EINT04_JACK
  EINT05_WLAN
  EINT06_AUXKEY
  EINT07_HOLDKEY
  EINT08_ACCEL2
* EINT09_PMU
    adpins
    adprem
    usbins
    usbrem
    rtcalarm
    second
    onkeyr
    onkeyf
    exton1r
    exton1f
    exton2r
    exton2f
    exton3r
    exton3f
  * batfull
    chghalt
    thlimon
    thlimoff
    usblimon
    usblimoff
    adcrdy
    onkey1s
    lowsys
    lowbat
    hightmp
    autopwrfail
    dwn1pwrfail
    dwn2pwrfail
    ledpwrfail
    ledovp
    ldo1pwrfail
    ldo2pwrfail
    ldo3pwrfail
    ldo4pwrfail
    ldo5pwrfail
    ldo6pwrfail
    hcidopwrfail
    hcidoovl
  EINT10_NULL
  EINT11_NULL
  EINT12_GLAMO
  EINT13_NULL
  EINT14_NULL
  EINT15_NULL

This shows a problem, false wake from suspend due to battery full
