This driver exposes the Keyboard Controller Style (KCS) interface on
Novoton NPCM7xx SoCs as a character device. Such SOCs are commonly used
as a BaseBoard Management Controller (BMC) on a server board, and KCS
interface is commonly used to perform the in-band IPMI communication
between the server and its BMC.

The KCS (Keyboard Controller Style) interface is used to perform in-band
IPMI communication between a server host and its BMC (BaseBoard Management
Controllers).
This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500)
as a character device. Such SOCs are commonly used as BMCs and this driver
implements the BMC side of the KCS interface.

This is the DRM tree that was merged into the mainline 4.14 kernel. The
ASPEED GFX DRM driver requires functionaliy that was included in this
tree, so we merge it back into the 4.13 OpenBMC tree.
This should have no impact on other parts of the BMC.

In order to use i2c from a cold boot, the i2c peripheral must be taken
out of reset. We request a shared reset controller each time a bus
driver is loaded, as the reset is shared between the 14 i2c buses.
On remove the reset is asserted, which only touches the hardware once
the last i2c bus is removed.
The reset is required as the I2C buses will not work without releasing
the reset. Previously the driver only worked with out of tree hacks
that released this reset before the driver was loaded. Update the
device tree bindings to reflect this.

This change introduces a proposed layout for describing FSI busses in
the device tree. While the bus is probe-able, we'd still like a method
of describing subordinate (eg i2c) busses that are behind FSI devices.
The FSI core will be responsible for matching probed slaves & engines to
their device tree nodes, so the FSI device drivers' probe() functions
will be passed a struct device with the appropriate of_node populated
where a matching DT node is found.

This change introduces an 'external mode' for GPIO-based FSI masters,
allowing the clock and data lines to be driven by an external source.
For example, external mode is selected by a user when an external debug
device is attached to the FSI pins.
To do this, we need to set specific states for the trans, mux and enable
gpios, and prevent access to clk & data from the FSI core code (by
returning EBUSY).
External mode is controlled by a sysfs attribute, so add the relevent
information to Documentation/ABI/

The dual tachometer feature is implemented in hardware with a TACHSEL
input to indicate the rotor under measurement, and exposed on the device
by extending the READ_FAN_SPEED_1 word with two extra bytes*. The need
to read the non-standard four-byte response leads to a cut-down
implementation of i2c_smbus_xfer_emulated() included in the driver.
Further, to expose the second rotor tachometer value to userspace the
values are exposed through virtual pages. We re-route accesses to
FAN_CONFIG_1_2 and READ_FAN_SPEED_1 on pages 23-28 (not defined by the
hardware) to the same registers on pages 0-5, and with the latter command we
extract the value from the second word of the four-byte response.
* The documentation recommends the slower rotor be associated with
TACHSEL=0, which corresponds to the first word of the response. The TACHSEL=0
measurement is used by the controller's closed-loop fan management to judge
target fan rate.

The implementation makes use of the new fan control virtual registers exposed
by the pmbus core. It mixes use of the default implementations with some
overrides via the read/write handlers to handle FAN_COMMAND_1 on the MAX31785,
whose definition breaks the value range into various control bands dependent on
RPM or PWM mode.

One of three different, mutually exclusive, values
"cpu" : ARM CPU reset on signal
"soc" : 'System on chip' reset
"system" : Full system reset
The value can also be set to "none" which indicates that no
reset of any kind is to be done via this watchdog. This assumes
another watchdog on the chip is to take care of resets.
* aspeed,external-signal - Generate external signal (WDT1 and WDT2 only)

commit 85fdee1eef1a9e48ad5716916677e0c5fbc781e3 upstream.
Enforcing exclusive ownership on upper/work dirs caused a docker
regression: https://github.com/moby/moby/issues/34672.
Euan spotted the regression and pointed to the offending commit.
Vivek has brought the regression to my attention and provided this
reproducer:
Terminal 1:
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
Terminal 2:
unshare -m
Terminal 1:
umount merged
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
mount: /root/overlay-testing/merged: none already mounted or mount point
busy
To fix the regression, I replaced the error with an alarming warning.
With index feature enabled, mount does fail, but logs a suggestion to
override exclusive dir protection by disabling index.
Note that index=off mount does take the inuse locks, so a concurrent
index=off will issue the warning and a concurrent index=on mount will fail.
Documentation was updated to reflect this change.

commit f007cad159e99fa2acd3b2e9364fbb32ad28b971 upstream.
This reverts commit 81f95076281fdd3bc382e004ba1bce8e82fccbce.
It causes random failures of firmware loading at resume time (well,
random for me, it seems to be more reliable for others) because the
firmware disabling is not actually synchronous with any particular
resume event, and at least the btusb driver that uses a workqueue to
load the firmware at resume seems to occasionally hit the "firmware
loading is disabled" logic because the firmware loader hasn't gotten the
resume event yet.
Some kind of sanity check for not trying to load firmware when it's not
possible might be a good thing, but this commit was not it.
Greg seems to have silently suffered the same issue, and pointed to the
likely culprit, and Gabriel C verified the revert fixed it for him too.

5) Correct datagram peek handling of empty SKBs, from Matthew Dawson.
6) Fix use after free in TIPC, from Eric Dumazet.
7) When replacing a route in ipv6 we need to reset the round robin
pointer, from Wei Wang.
8) Fix bug in pci_find_pcie_root_port() which was unearthed by the
relaxed ordering changes, from Thierry Redding. I made sure to get
an explicit ACK from Bjorn this time around :-)

Looks like this was accidentally missed, so still add s390x
as supported eBPF JIT arch to bpf_jit_enable.
