[PATCH 3/4] arm64: dts: rockchip: rk3328 usb3 controller node

[lindsey.stanpoor]

From: Cameron Nemo <cnemo@tutanota.com>

RK3328 SoCs have one USB 3.0 OTG controller which uses DWC_USB3
core's general architecture. It can act as static xHCI host
controller, static device controller, USB 3.0/2.0 OTG basing
on ID of USB3.0 PHY.

Hi Cameron,

Increase the version number for each new patch serie.

git format-patch -v4 -4 HEAD

In a previous comment I gave a sort example.
However, this patch serie is about usb3, so only touch the things
related to usb3 and leave the &uart2 node (legacy ;) ) untouched.

Improve the way in which your patches are send.

Your previous serie was incomplete.
Submit all patches with the same news server (Gmail for example) that
can handle plain text, because else you get 2 different Message-Ids:
<20200826171230.17041-2-lindsey.stanpoor@gmail.com>
<20200826170623.15469-2-travelvia@airmail.cc>

git send-email --suppress-cc all --annotate --to <..> --cc <..> <patch1
patch2>

Not sure how robh filters patches, but your serie 'must' show up in the
link below or else wait for an eternity to get a ack-by.
