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] sky2: allow mac to come from dt
|
|
||||||
|
|
||||||
The driver reads the mac address from the device registers which would
|
|
||||||
need to have been programmed by the bootloader. This patch adds
|
|
||||||
the ability to pull the mac from devicetree via the aliases/sky2 node.

|

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 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.

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.
