[PATCHv2 0/7] Add support for USB OTG on STM32F7

[Amelie Delaunay]

The STM32F7 MCU family embeds two DWC2 USB OTG cores. One core is USB
OTG FS and the other is USB OTG HS. The USB FS core only works with its
internal phy whilst the USB HS core can work in HS with external ULPI phy
or in FS/LS with the on-chip FS phy.

I have applied these three patches. Should I take the rest? They seems
like they could go upstream through the ARM maintainers.

I will take other DT patches in my PR.

Concerning "ARM: dts: stm32: Add USB HS support for STM32F746 MCU" patch 
I prefer also to take it. This patch adds some pinctrl groups but stm32 
pinctrl bindings will change in my next PR (we will use a macro to 
define pins instead of using defined values). So if you push the DT 
patch through your pull request there will be a merge issue.
It is possible that I take also this one ?

Alex

In that case, it's best if you take them all :-) Here's my Ack:

Acked-by: Felipe Balbi <felipe.balbi@linux.intel.com>

I'll drop them from my tree now

Ok perfect, I will take DT patches (3 to 7) and I let you take patch 1&2 
in your tree.

Well, I have dropped them from my tree. Please two 1-7 through yours.

Hum, ok for this patchset but IMO it is better (next time) that you take 
driver pacthes in your tree and I take only DT patches in mine.
No ?

I thought that patches 1 and 2, as they are "driver" patches, had to be 
applied on USB tree (so Felipe's one), and the others (3 to 7) had to be 
applied on STM32-DT tree (Alex's one). Did I miss something?

patch 1 is documentation, right? Without the documentation patch,
checkpatch will cringe :-) So either way works.

If you insist, I can take 1-2 through my tree. No worries.

I don't want to insist :) but for me it is better (and more safe) if you 
take patch 1&2 in your tree, and will take others in mine.

Patches 3 to 7 applied on stm32-dt-for-v4.15 branch.
Currently USB stack is not enabled by default (and will not be). If you 
plan to use USB don't forget to create a reserved memory region for DMA 
pool (as DMA and caches are not friends on cortex-M7) in devicetree.
Reserved memory region for DMA pool support will be added in stm32F7 and 
stm32H7 devicetree as soon series "ARM: NOMMU: MPU updates" from 
Vladimir Murzin will be merged.

Regards
Alex
