This patch add a quirk to be compatible for AMD NL SoC
Some specific behaviors on NL:
- configure USB3 PIPE registers
- enable GCTL disscramble
- enable U2EXIT_LFPS
- enable hibernation at the global level
- set LPM errata dissabled

Hi,
The series of patches add AMD NL SoC support for DesignWare USB3 OTG IP with PCI
bus glue layer. And add a role switch feature with debugfs in order that create
an entry to alternative roles between host and device. Because of the limitation
for PCI-based temporary platform currently, it's una
This patch adds some undefined register macros on DWC3 spec 2.80a, these macros
will be used on AMD NL specific configuration.

This patch implemented a feature to dynamic switch to host or device role under
debugfs for some physical limitation that unable to leverage connector A/B
cables (ID pin) to change roles.
The default role should be set as OTG mode. Then use below commands:
[1] switch to host:

Changes since v2:
* switch to using devm_ allocation
* remove unused platform_device
Changes since v1:
* split cache sharing fix and cleanups into separate patches
Octavian Purdila (3):
mfd: viperboard: allocate I/O buffer separately
mfd: viperboard: switch to devm_ allocation
mfd:
Currently the I/O buffer is allocated part of the device status
structure, potentially sharing the same cache line with other members
in this structure.
Allocate the buffer separately, to avoid the I/O operations corrupting
the device status structure due to cache line sharing.

Commit 0cce2eda19923e5e5ccc8b042dec5af87b3ffad0
USB: fix LANGID=0 regression
defaults to a langid of 0x0409 if it's not properly implemented by the
device. Explain with a higher level error message what this means.

This patch adds GPIO and IRQ support for the Diolan DLN-2 GPIO module.
Information about the USB protocol interface can be found in the
Programmer's Reference Manual [1], see section 2.9 for the GPIO
module commands and responses.
[1] https://www.diolan.com/downloads/dln-api
Some GPIO chips (e.g. the DLN2 USB adapter) have blocking get/set
operation but do not need a threaded irq handler.
