* The GW16083 interfaces with a Ventana baseboard via the PCIe bus, an i2c
* bus (i2c2), and a couple of GPIO's. On the PCIe bus is an i210 GigE with
* its MAC connected to Port4 of a Marvell MV88E6176 7-port GigE switch via
* MDIO and RGMII. Ports 0-3 are standard copper RJ45 but Ports 5 and 6
* connect to Marvell MV88E1111 dual-mode Copper/Fiber PHY's over SGMII and
* MDIO. The PHY's have both an RG45 for copper and an SFP module.

From 804f57b1a63c7435fe43b36942581cc6c79ebb5c Mon Sep 17 00:00:00 2001
From: Lucas Stach <l.stach@pengutronix.de>
Date: Wed, 5 Mar 2014 14:25:51 +0100
Subject: [PATCH] PCI: designware: Use new OF interrupt mapping when possible
Use new OF interrupt mapping (of_irq_parse_and_map_pci()) when possible.
This is the recommended method of doing the IRQ mapping. For old
devicetrees we fall back to the previous practice.
This makes INTB, INTC, and INTD work on i.MX.

Subject: [PATCH] ARM: dts: imx: drop invalid size and address cells properties
Those two properties should have been set to zero, which
is the same as not specifying them.
Having address-cells set to 1 causes OF interrupt
mapping routines to add 1 to the interrupt-cells
property and as result fail because all calculations
are off by one.

View File

@ -1,86 +0,0 @@
This fixes a boot hang observed when the bootloader
already enabled the PCIe link for it's own use. The
fundamental problem is that Freescale forgot to wire
up the core reset, so software doesn't have a sane way
to get the core into a defined state.
According to the DW PCIe core reference manual configuration
of the core may only happen when the LTSSM is disabled, so
this is one of the first things we need to do. Apparently
this isn't safe to do when the LTSSM is in any other state
than "detect" as we observe an instant machine hang when
trying to do so while the link is already up.
As a workaround force LTSSM into detect state right before
hitting the disable switch.

PCI: imx6: fix occasional link failure
According to the IMX6 reference manuals, REF_SSP_EN (Reference clock enable
for SS function) must remain deasserted until the reference clock is running
at the appropriate frequency.
Without this patch we find a high link failure rate (>5%) on certain
IMX6 boards at various temperatures.

net: igb: add i210/i211 support for phy read/write
The i210/i211 uses the MDICNFG register for the phy address instead of the
MDIC register.

net: igb: add phy read/write functions that accept phy addr
Add igb_write_reg_gs40g/igb_read_reg_gs40g that can be passed a phy address.
The existing igb_write_phy_reg_gs40g/igb_read_phy_reg_gs40g become wrappers
to this function.

net: igb: register mii_bus for SerDes w/ external phy
If an i210 is configured for 1000BASE-BX link_mode and has an external phy
specified, then register an mii bus using the external phy address as
a mask.
An i210 hooked to an external standard phy will be configured with a link_mo
of SGMII in which case phy ops will be configured and used internall in the
igb driver for link status. However, in certain cases one might be using a
backplane SerDes connection to something that talks on the mdio bus but is
not a standard phy, such as a switch. In this case by registering an mdio
bus a phy driver can manage the device.

View File

@ -1,58 +0,0 @@
This patch allows passing in the gpio output mask used for GPIO0-7 on the
PLX PCIe bridge. These GPIO's are used for PERST# on the downstream ports.
Allowing the kernel to override the default configuration allows for keeping
specific devices held in reset. One important use of this is to allow
temporarily disabling devices that may request too many resources such as
an unprogrammed i210 device.
