Sorry to enter this thread a bit late.
About the number of probe deferred messages, I proposed a simple patch to
reduce them:
https://lkml.org/lkml/2013/8/20/218
I was wondering how many messages this patch could save...

Hi Sergei,
I think this patch is too much delay. I recommend you better to develop
this driver based on latest extcon-next branch[1].

I could spend some time on this issue a week later.
I'd like to check whether there is any bugs in the driver itself.
Otherwise, blacklist this specific device for LPM.

The comment for ahbcfg for rk3066 parameters (also used for rk3288)
claimed that ahbcfg was INCR16, but it wasn't. Since the bits weren't
shifted properly, the 0x7 ended up being masked and we ended up
programming 0x3 for the HBstLen. Let's set it to INCR16 properly.

Since composite now overwrites bcdUSB for any gadget, remove
setting it in legacy gadgets. All legacy gadgets set 0x0200, the
same as the value additionally set by composite, so there is no
