Grzegorz Jaszczyk eb6a1fcb53 phy: mvebu-cp110-comphy: Add SMC call support
Keep the exact same list of supported configurations but first try to
use the firmware's implementation. If it fails, try the legacy method:
Linux implementation.

Linus Torvalds f90d64483e USB/PHY patches for 5.1-rc1
Here is the big USB/PHY driver pull request for 5.1-rc1.
 
 The usual set of gadget driver updates, phy driver updates (you will
 have a merge issue with Kconfig and Makefile), xhci updates, and typec
 additions.  Also included in here are a lot of small cleanups and fixes
 and driver updates where needed.
 
 All of these have been in linux-next for a while with no reported
 issues.

Russell King 14dc100b44 phy: armada38x: add common phy support
Add support for the Armada 38x common phy to allow us to change the
speed of the Ethernet serdes lane.  This driver only supports
manipulation of the speed, it does not support configuration of the
common phy.

Miquel Raynal cc8b7a0ae8 phy: add A3700 UTMI PHY driver
Marvell Armada 3700 SoC has two USB controllers, each of them being
wired to an internal UTMI PHY. Add a driver to control them.

Igal Liberman worked on supporting the PHY, I took the while 'register
configuration' from his work and rewrote almost entirely the
driver/bindings around it.

Miquel Raynal 9695375a3f phy: add A3700 COMPHY support
Add a driver to support COMPHY, a hardware block providing shared
serdes PHYs on Marvell Armada 3700. This driver uses SMC calls and
rely on having an up-to-date firmware.

SATA, PCie and USB3 host mode have been tested successfully with an
ESPRESSObin. (HS)SGMII mode cannot be tested with this platform.

Evan worked on the original driver structure and Grzegorz on the SMC
calls rework. The structure of this driver has been copied from
Antoine Tenart work on CP110 COMPHY driver.

Antoine Tenart d0438bd6aa phy: add the mvebu cp110 comphy driver
On the CP110 unit, which can be found on various Marvell platforms such
as the 7k and 8k (currently), a comphy (common PHYs) hardware block can
be found. This block provides a number of PHYs which can be used in
various modes by other controllers (network, SATA ...). These common
PHYs must be configured for the controllers using them to work correctly
either at boot time, or when the system runs to switch the mode used.
This patch adds a driver for this comphy hardware block, providing
callbacks for the its PHYs so that consumers can configure the modes
used.

As of this commit, two modes are supported by the comphy driver: sgmii
and 10gkr.
