Hi,

after debugging more I found something interesting:
good: 4.19-rc4 mainline + letux-4.18 dtb
good: 4.19-rc4 letux + letux-4.18.dtb
bad: 4.19-rc4 mainline + letux-4.19-rc4 dtb

I am testing suspend with this small set of modules loaded:

usb_f_ecm              16384  1 
g_ether                16384  0 
usb_f_rndis            20480  2 g_ether
u_ether                20480  3 usb_f_ecm,g_ether,usb_f_rndis
libcomposite           45056  3 usb_f_ecm,g_ether,usb_f_rndis
configfs               32768  4 usb_f_ecm,usb_f_rndis,libcomposite
omap2430               16384  0 
phy_twl4030_usb        16384  2 
musb_hdrc             106496  2 omap2430,phy_twl4030_usb
twl4030_charger        20480  0 
industrialio           53248  1 twl4030_charger
twl4030_pwrbutton      16384  0 
bq27xxx_battery_hdq    16384  0 
bq27xxx_battery        20480  1 bq27xxx_battery_hdq
omap_hdq               16384  0 
in case of letux kernel: additionally
gnss_w2sg0004

good means:
device sleeps for around 300 seconds via rtc.

bad means:
device wakes up immediately.

Regards,
Andreas
