This patch introduces new library callback (ArmadaSoCGpioGet ()),
which dynamically allocates and fills EmbeddedGpio's
GPIO_CONTROLLER structure with the SoC description of GPIO controllers.
Because the library header is indirectly used in many modules,
update all dependencies after including EmbeddedGpio.h.

This patch extends library with GPIO devices per-board
description. Both embedded SoC controllers and
I2C IO expanders are supported. Add a helper routine
for obtaining information about the latter.

Following patches will add two drivers that are capable
of producing the generic EMBEDDED_GPIO protocol. In order
to handle a situation, when the consumer module attempts
to locate and open a proper protocol, add a library
helper function.
In order to ease description of used GPIO pins and controllers
of the Armada 7k8k platforms, add the common enum types.

Hi Leif,
Sorry for omitting. I confirm the patch is:
Contributed-under: TianoCore Contribution Agreement 1.1
Will you add it (as well as remove class from the subject) or should I resubmit?
Thanks,
Marcin

Introduce new callback that can provide information
about GPIO SoC controllers, as well as on-board
I2C IO expanders. According ArmadaSoCDescLib
ArmadaBoardDescLib routines are used for
obtaining required data.

Marvell Armada 7k/8k SoCs comprise integrated GPIO controllers,
one in AP806 and two in each south bridge hardware blocks.
This patch introduces support for them. The new driver implements
a generic EMBEDDED_GPIO protocol.
In order to ease description of used GPIO pins and controllers
of the Armada 7k8k platforms, add a common enum type.
Based on original work of Jing Hua <jinghua@marvell.com>.

Hitherto I2c solution used same macros, defined in multiple
places. Move them to a new common header.

Marvell Armada 7k/8k-based platforms may use Pca95xx to extend
amount of the GPIO pins.
This patch introduces support for them. The new driver implements
a generic EMBEDDED_GPIO protocol.
In order to ease description of used PCA9XXX controllers
add a common enum type. It can be used e.g. in the board description
library to specify the expander model on a board (instead of passing
a raw number). Update relevant libraries.
Driver is based on initial work done by Allen Yan <yanwei@marvell.com>.

pins handling. Update relevant boards .dsc files with
IO expander information.

To abstract the initialization required for non-discoverable devices,
which is often platform specific (e.g. enable GPIO-driven power supply),
introduce a NonDiscoverableInitLib for use by the NonDiscoverable code,
for which each platform can supply its own version.
Add XHCI power supply (so called 'VBUS') enabling routines
for supported platforms (Armada70x0Db, Armada80x0Db, Armada80x0McBin).

So, I was about to say that apart from the "class" to be deleted from
3/12 subject line, things were fine so I was going to fix that locally
and push.
However. 3/12 is missing the Contributed-under tag.
Can you please separately confirm that it is intended to be
contributed under TianoCore Contribution Agreement 1.1?
