approximately the same as
without any patch.
With a device connected the device does not enumerate
after resume. A rmmod ehci-omap ; modprobe ehci-omap
does not make it reenumerade.
So there is still something wrong here.

Hi,
I booted a 4.15 kernel without udev and loaded modules piece by piece to analyze
pm problems. modprobe ehci-omap increases current by around 35mA and
also rmmod ehci-omap does not let it go down at all.
I expect that removing hardware does the same thing
Also suspend current increases by aro
lated stuff
which needs to be enabled.
Also interrupts are enabled, as it was the original idea
of calling musb_start() in musb_resume() according to
Commit 6fc6f4b87cb3 ("usb: musb: Disable interrupts on suspend,
enable them on resume")

unbalanced way by fixing musb_core.c
Fixing 1. is enough on gta04 to fix charging and hide 2. enough to
have gadget working for the most common usecases. (not using
twl4030-charger would not work yet)
But in the longer term 2. has to be fixed too.
