Subject: [RFC 2/2] net: emac: add support for device-tree based PHY discovery
and setup
To: netdev@vger.kernel.org,
devicetree@vger.kernel.org
Cc: David S. Miller <davem@davemloft.net>,
Ivan Mikhaylov <ivan@de.ibm.com>,
Mark Rutland <mark.rutland@arm.com>,
Rob Herring <robh+dt@kernel.org>
This patch adds glue-code that allows the EMAC driver to interface
with the existing dt-supported PHYs in drivers/net/phy.
Because currently, the emac driver maintains a small library of
supported phys for in a private phy.c file located in the drivers
directory.
The support is limited to mostly single ethernet transceiver like the:
CIS8201, BCM5248, ET1011C, Marvell 88E1111 and 88E1112, AR8035.
However, routers like the Netgear WNDR4700 and Cisco Meraki MX60(W)
have a 5-port switch (QCA8327N) attached to the MDIO of the EMAC.
The switch chip has already a proper phy-driver (ar8216) that uses
the generic phy library.

Subject: [PATCH] usb: xhci: add firmware loader for uPD720201 and uPD720202
w/o ROM
This patch adds a firmware loader for the uPD720201K8-711-BAC-A
and uPD720202K8-711-BAA-A variant. Both of these chips are listed
in Renesas' R19UH0078EJ0500 Rev.5.00 "User's Manual: Hardware" as
devices which need the firmware loader on page 2 in order to
work as they "do not support the External ROM".
The "Firmware Download Sequence" is describe in chapter
"7.1 FW Download Interface" R19UH0078EJ0500 Rev.5.00 page 131.
The firmware "K2013080.mem" is available from a USB3.0 Host to
PCIe Adapter (PP2U-E card) "Firmware download" archive. An
alternative version can be sourced from Netgear's WNDR4700 GPL
archives.
The release notes of the PP2U-E's "Firmware Download" ver 2.0.1.3
(2012-06-15) state that the firmware is for the following devices:
- uPD720201 ES 2.0 sample whose revision ID is 2.
- uPD720201 ES 2.1 sample & CS sample & Mass product, ID is 3.
- uPD720202 ES 2.0 sample & CS sample & Mass product, ID is 2.
If someone from Renesas is listening: It would be great, if these
firmwares could be added to linux-firmware.git.

Subject: [PATCH] usb: xhci: force MSI for uPD720201 and
uPD720202
The APM82181 does not support MSI-X. When probed, it will
produce a noisy warning.
