[PATCH 0/3] usb: dwc2: Fix power saving general issues.

[PATCH 0/3] usb: dwc2: Fix power saving general issues.

[Artur Petrosyan]

This patch set is part of multiple series and is
continuation of the "usb: dwc2: Fix and improve
power saving modes" patch set.
(Patch set link: https://marc.info/?l=linux-usb&m=160379622403975&w=2).

The patches that were included in the "usb: dwc2:
Fix and improve power saving modes" which was submitted
earlier was too large and needed to be split up into
smaller patch sets. So this is the first series in the
whole power saving mode fixes.

Each remaining patch set have dependency on previous set
and will be submitted after each of them are integrated.

The series includes the following patch sets with multiple patches
by below order.
 1. usb: dwc2: Fix power saving general issues.
 2. usb: dwc2: Fix Partial Power down issues.
 3. usb: dwc2: Add clock gating support.
 4. usb: dwc2: Fix Hibernation issues

Changes since V1:
- Added Fixes tag and stable kernel in below patches to point to the commits the
  fixes are addressing
  1. "usb: dwc2: Prevent core suspend when port connection flag is 0"
  2. "usb: dwc2: Fix HPRT0.PrtSusp bit setting for HiKey 960 board."
- Updated the changelog of "usb: dwc2: Add default param to control power optimization." patch. 


Artur Petrosyan (3):
  usb: dwc2: Add default param to control power optimization.
  usb: dwc2: Fix HPRT0.PrtSusp bit setting for HiKey 960 board.
  usb: dwc2: Prevent core suspend when port connection flag is 0

You only sent 3 patches, not 4.

So this makes no sense to me, what am I supposed to do?

The 4 items that are listed are patch sets. The first patch set that I 
have sent is "usb: dwc2: Fix power saving general issues.", which 
includes the 3 patches that have been sent.

I wrote the other 3 patch set names in the list to indicate that I will 
send them after this "usb: dwc2: Fix power saving general issues." patch 
set is integrated to mainline.

I'm not taking this first patch as-is, sorry, see my comments on it
already.

I took patch 2 and 3 though.
