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>,

||||||
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] net: emac: fix reset timeout with AR8035 phy
|
|
||||||
|
|
||||||
This patch fixes a problem where the AR8035 PHY can't be
|
|
||||||
detected on an Cisco Meraki MR24, if the ethernet cable is
|
|
||||||
not connected on boot.
|
|
||||||
|
|
||||||
Russell Senior provided steps to reproduce the issue:
|
|
||||||
|Disconnect ethernet cable, apply power, wait until device has booted,
|
|
||||||
|plug in ethernet, check for interfaces, no eth0 is listed.
|
|
||||||
|
|
|
||||||
|This appears to be a problem during probing of the AR8035 Phy chip.
|
|
||||||
|When ethernet has no link, the phy detection fails, and eth0 is not
|
|
||||||
|created. Plugging ethernet later has no effect, because there is no
|
|
||||||
|interface as far as the kernel is concerned. The relevant part of
|
|
||||||
|the boot log looks like this:
|
|
||||||
|this is the failing case:
|
|
||||||
|
|
|
||||||
|[ 0.876611] /plb/opb/emac-rgmii@ef601500: input 0 in RGMII mode
|
|
||||||
|[ 0.882532] /plb/opb/ethernet@ef600c00: reset timeout
|
|
||||||
|[ 0.888546] /plb/opb/ethernet@ef600c00: can't find PHY!
|
|
||||||
|and the succeeding case:
|
|
||||||
|
|
|
||||||
|[ 0.876672] /plb/opb/emac-rgmii@ef601500: input 0 in RGMII mode
|
|
||||||
|[ 0.883952] eth0: EMAC-0 /plb/opb/ethernet@ef600c00, MAC 00:01:..
|
|
||||||
|[ 0.890822] eth0: found Atheros 8035 Gigabit Ethernet PHY (0x01)
|
|
||||||
|
|
||||||
Based on the comment and the commit message of
|
|
||||||
commit 23fbb5a87c56 ("emac: Fix EMAC soft reset on 460EX/GT").
|
|
||||||
This is because the AR8035 PHY doesn't provide the TX Clock,
|
|
||||||
if the ethernet cable is not attached. This causes the reset
|
|
||||||
to timeout and the PHY detection code in emac_init_phy() is
|
|
||||||
unable to detect the AR8035 PHY. As a result, the emac driver
|
|
||||||
bails out early and the user left with no ethernet.
|
|
||||||
|
|
||||||
In order to stay compatible with existing configurations, the driver
|
|
||||||
tries the current reset approach at first. Only if the first attempt
|
|
||||||
timed out, it does perform one more retry with the clock input
|
|
||||||
temporarily switched to the internal clock source for just the
|
|
||||||
duration of the reset.

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

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.
