[PATCH v3 0/6] Add dwc3 usb3 DT node and various phy cleanup

[PATCH v3 0/6] Add dwc3 usb3 DT node and various phy cleanup

[Peter Griffin]

Hi Maxime,

This series primarily adds the dwc3 DT node which activates the usb3 controller on
the stih407-b2120, stih410-b2120 and stih418-b2199 platforms.

As part of getting this working I noticed an error with the picophyreset which 
stops the controller working which I've also fixed.

regards,

Peter.

Changes in v3:
- Add miphys8lp options properties for stih418 (Pete)
- Add support for stih418-b2199 (Max)
- Only enable usb3 controller in the board file (Max)
- Fix superflous '\n' (Lee)
- Rebase series on v4.1-rc1 (Pete)

NB: Since v2 some patches were taken into the phy and ahci trees which I've now
removed from the series.

Changes in v2:
- Update commit to explicitly say no ABI breakage (Rob)
- Rebase series on v4.0-rc6 (Pete)
- Collect up Acks (Pete)

[PATCH v3 1/6] ARM: DT: STi: STiH407: Update picophyreset for the usb3 controllers usb2 phy

[Peter Griffin]

Ths picophyreset is incorrectly defined, which stops the usb2 phy being
taken out of reset.

[PATCH v3 2/6] ARM: DT: STi: STiH407: Add dwc3 usb3 DT node.

[Peter Griffin]

Now that both usb2 and usb3 phy drivers, and also the ST dwc3 glue code
are all present upstream, we can add the dwc3 DT node and have a working
usb3 controller on stih407-b2120 and stih410-b2020.

[PATCH v3 3/6] usb: dwc3: dwc3-st: Update the incorrect DT dwc3 example.

[Peter Griffin]

There is a subtle typo phys-names should be phy-names. Using the
current example means you don't have working usb (as you fail to
obtain the phys). Also update the example to use the generic phy
type constants which are now used for miphy28.

Additionally also remove the unnecessary new line in the example.

only this patch ? Sure. Just post on linux-usb and I'll fetch it from
there.

Yes, I think the test will go via Maximes STI tree

Brilliant, thanks. I've sent it see here https://lkml.org/lkml/2015/5/7/809
with linux-usb on CC (sorry for missing that off the first time round)
