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
