Subject: e1000: prevent oops when adapter is being closed and reset simultaneously
Date: Mon, 25 Nov 2013 13:30:21 +0800
This change is based on a similar change made to e1000e support in
commit bb9e44d0d0f4 ("e1000e: prevent oops when adapter is being closed
and reset simultaneously"). The same issue has also been observed
on the older e1000 cards.
Here, we have increased the RESET_COUNT value to 50 because there are too
many accesses to e1000 nic on stress tests to e1000 nic, it is not enough
to set RESET_COUT 25. Experimentation has shown that it is enough to set
RESET_COUNT 50.

Subject: serial: pch_uart: Remove __initdata annotation from dmi_table
Date: Mon, 29 Jul 2013 09:58:14 -0700
The dmi_table is best accessed from the probe function, which is not
an __init function. Drop the __initdata annotation from the dmi_table
to avoid the section mismatch compiler warnings:

Subject: pch_gbe: Add MinnowBoard support
Date: Sat, 18 May 2013 14:46:00 -0700
The MinnowBoard uses an AR803x PHY with the PCH GBE which requires
special handling. Use the MinnowBoard PCI Subsystem ID to detect this
and add a pci_device_id.driver_data structure and functions to handle
platform setup.
The AR803x does not implement the RGMII 2ns TX clock delay in the trace
routing nor via strapping. Add a detection method for the board and the
PHY and enable the TX clock delay via the registers.
This PHY will hibernate without link for 10 seconds. Ensure the PHY is
awake for probe and then disable hibernation. A future improvement would
be to convert pch_gbe to using PHYLIB and making sure we can wake the
PHY at the necessary times rather than permanently disabling it.

Subject: mfd: lpc_sch: Accomodate partial population of the MFD devices
Date: Sat, 18 May 2013 14:45:52 -0700
commit 5829e9b64e657560e840dc0ecfee177cb002cd69 upstream
The current probe aborts if any of the 3 base address registers are
disabled. On a TunnelCreek system I am working on, this resulted in the
SMBIOS and GPIO devices being removed when it couldn't read the base
address for the watchdog timer.
This patch accommodates partial population of the lpc_sch_cells array and
only aborts if all the base address registers are disabled. A max size
array is allocated and the individual device cells are added to it after
their base addresses are successfully determined. This simplifies the
code a bit by removing the need for the separate tunnelcreek cells array
and combining some of the add/remove logic.

Add console support to pch_uart. To enable append e.g.
console=ttyPCH0,115200 to your kernel command line.
This is not expected work on CM-iTC boards due to their having a different
clock.

Subject: pch_uart: Use uartclk instead of base_baud
Date: Thu, 1 Mar 2012 15:59:37 -0800
The term "base baud" refers to the fastest baud rate the device can communicate
at. This is clock/16. pch_uart is using base_baud as the clock itself. Rename
the variables to be semantically correct.

Subject: pch_uart: Add Fish River Island II uart clock quirks
Date: Thu, 1 Mar 2012 15:59:38 -0800
Add support for the Fish River Island II (FRI2) UART clock following the CM-iTC
quirk handling mechanism. Depending on the firmware installed on the device, the
FRI2 uses a 48MHz or a 64MHz UART clock. This is detected with DMI strings.
Add similar UART clock quirk handling to the pch_console_setup() function to
enable kernel messages on boards with non-standard UART clocks.
Per Alan's suggestion, abstract out UART clock selection into
pch_uart_get_uartclk() to avoid code duplication.

Subject: pch_uart: Add user_uartclk parameter
Date: Thu, 1 Mar 2012 15:59:39 -0800
For cases where boards with non-default clocks are not yet added to the kernel
or when the clock varies across hardware revisions, it is useful to be
able to specify the UART clock on the kernel command line.
Add the user_uartclk parameter and prefer it, if set, to the default and
board specific UART clock settings. Specify user_uartclock on the command-line
with "pch_uart.user_uartclk=48000000".
