The Wilco Embedded Controller is able to send telemetry data
which is useful for enterprise applications. A daemon running on
the OS sends a command to the EC via a write() to a char device,
and can read the response with a read(). The write() request is
verified by the driver to ensure that it is performing only one
of the whitelisted commands, and that no extraneous data is
being transmitted to the EC. The response is passed directly
back to the reader with no modification.
The character device will appear as /dev/wilco_telemN, where N
is some small non-negative integer, starting with 0. Only one
process may have the file descriptor open at a time. The calling
userspace program needs to keep the device file descriptor open
between the calls to write() and read() in order to preserve the
response. Up to 32 bytes will be available for reading.
For testing purposes, try requesting the EC's firmware build
date, by sending the WILCO_EC_TELEM_GET_VERSION command with
argument index=3. i.e. write [0x38, 0x00, 0x03]
to the device node. An ASCII string of the build date is
returned.

The Wilco Embedded Controller can create custom events that
are not handled as standard ACPI objects. These events can
contain information about changes in EC controlled features,
such as errors and events in the dock or display. For example,
an event is triggered if the dock is plugged into a display
incorrectly. These events are needed for telemetry and
diagnostics reasons, and for possibly alerting the user.
These events are triggered by the EC with an ACPI Notify(0x90),
and then the BIOS reads the event buffer from EC RAM via an
ACPI method. When the OS receives these events via ACPI,
it passes them along to this driver. The events are put into
a queue which can be read by a userspace daemon via a char device
that implements read() and poll(). The event queue acts as a
circular buffer of size 64, so if there are no userspace consumers
the kernel will not run out of memory. The char device will appear at
/dev/wilco_event{n}, where n is some small non-negative integer,
starting from 0. Standard ACPI events such as the battery getting
plugged/unplugged can also come through this path, but they are
dealt with via other paths, and are ignored here.
To test, you can tail the binary data with
$ cat /dev/wilco_event0 | hexdump -ve '1/1 "%x\n"'
and then create an event by plugging/unplugging the battery.

All currently known ECs in the wild are very sensitive to timing.
Specifically the ECs are known to drop a transfer if more than 8 ms
passes from the assertion of the chip select until the transfer
finishes.
Let's use the new feature introduced in the patch (spi: Allow SPI
devices to request the pumping thread be realtime") to request the SPI
pumping thread be realtime. This means that if we get shunted off to
the SPI thread for whatever reason we won't get downgraded to low
priority.
NOTES:
- We still need to keep ourselves as high priority since the SPI core
doesn't guarantee that all transfers end up on the pumping thread
(in fact, it tries pretty hard to do them in the calling context).
- If future Chrome OS ECs ever fix themselves to be less sensitive
then we could consider adding a property (or compatible string) to
not set this property. For now we need it across the board.

In commit 37a186225a0c ("platform/chrome: cros_ec_spi: Transfer
messages at high priority") we moved transfers to a high priority
workqueue. This helped make them much more reliable.
...but, we still saw failures.
We were actually finding ourselves competing for time with dm-crypt
which also scheduled work on HIGHPRI workqueues. While we can
consider reverting the change that made dm-crypt run its work at
HIGHPRI, the argument in commit a1b89132dc4f ("dm crypt: use
WQ_HIGHPRI for the IO and crypt workqueues") is somewhat compelling.
It does make sense for IO to be scheduled at a priority that's higher
than the default user priority. It also turns out that dm-crypt isn't
alone in using high priority like this. loop_prepare_queue() does
something similar for loopback devices.
Looking in more detail, it can be seen that the high priority
workqueue isn't actually that high of a priority. It runs at MIN_NICE
which is _fairly_ high priority but still below all real time
priority.
Should we move cros_ec_spi to real time priority to fix our problems,
or is this just escalating a priority war? I'll argue here that
cros_ec_spi _does_ belong at real time priority. Specifically
cros_ec_spi actually needs to run quickly for correctness. As I
understand this is exactly what real time priority is for.
There currently doesn't appear to be any way to use the standard
workqueue APIs with a real time priority, so we'll switch over to
using using a kthread worker. We'll match the priority that the SPI
core uses when it wants to do things on a realtime thread and just use
"MAX_RT_PRIO - 1".
This commit plus the patch ("platform/chrome: cros_ec_spi: Request the
SPI thread be realtime") are enough to get communications very close
to 100% reliable (the only known problem left is when serial console
is turned on, which isn't something that happens in shipping devices).
Specifically this test case now passes (tested on rk3288-veyron-jerry):
dd if=/dev/zero of=/var/log/foo.txt bs=4M count=512&
while true; do
ectool version > /dev/null;
done
It should be noted that "/var/log" is encrypted (and goes through
dm-crypt) and also passes through a loopback device.

This driver implements a slim layer to enable the ChromeOS
EC kernel stack (cros_ec) to communicate with ChromeOS EC
firmware running on the Intel Integrated Sensor Hub (ISH).
The driver registers a ChromeOS EC MFD device to connect
with cros_ec kernel stack (upper layer), and it registers a
client with the ISH Transport Protocol bus (lower layer) to
talk with the ISH firwmare. See description of the ISHTP
protocol at Documentation/hid/intel-ish-hid.txt

The Chrome OS EC driver attaches to devices using the of_match_table
even when ACPI is the underlying firmware. It does this using the
magic PRP0001 ACPI HID, which tells ACPI to go find an OF compatible
string under the hood and match on that.
The cros_ec_spi driver needs to provide the of_match_table regardless
of whether CONFIG_OF is enabled or not, since the table is used by
ACPI for PRP0001 devices.

A Property is typically a data item that is stored to NVRAM
by the EC. Each of these data items has an index associated
with it, known as the Property ID (PID). Properties may have
variable lengths, up to a max of WILCO_EC_PROPERTY_MAX_SIZE
bytes. Properties can be simple integers, or they may be more
complex binary data.
This patch adds support for getting and setting properties.
This will be useful for setting the charge algorithm and charge
schedules, which all use properties.

Supplying also external devices, the DisplayPort connector
and the USB role switch, software fwnodes. After this the
driver has access to all the components tied to the USB
Type-C connector and can start creating software node
references to actually associate them with the USB Type-C
connector device.

In ACPI, and now also in DT, the USB connectors usually have
their own device nodes. In case of USB Type-C, those
connector (port) nodes are child nodes of the controller or
PHY device, in our case the fusb302. The software fwnodes
allow us to create a similar child node for fusb302 that
represents the connector also on Intel CHT.
This makes it possible replace the fusb302 specific device
properties which were deprecated with the common USB
connector properties that tcpm.c is able to use directly.

Software nodes provide two features that we will need later.
1) Software nodes can have references to other software nodes.
2) Software nodes can exist before a device entry is created.

Registering real device entries (struct device) for the mode
muxes as well as for the orientation switches.
The Type-C mux code was deliberately attempting to avoid
creation of separate device entries for the orientation
switch and the mode switch (alternate modes) because they
are not physical devices. They are functions of a single
physical multiplexer/demultiplexer switch device.
Unfortunately because of the dependency we still have on the
underlying mux device driver, we had to put in hacks like
the one in the commit 3e3b81965cbf ("usb: typec: mux: Take
care of driver module reference counting") to make sure the
driver does not disappear from underneath us. Even with
those hacks we were still left with a potential NUll pointer
dereference scenario, so just creating the device entries,
and letting the core take care of the dependencies. No more
hacks needed.

Fix the issue found while running kernel with the option
CONFIG_DEBUG_TEST_DRIVER_REMOVE.
Driver 'mlx-platform' registers 'i2c_mlxcpld' device and then registers
few underlying 'i2c-mux-reg' devices:
priv->pdev_i2c = platform_device_register_simple("i2c_mlxcpld", nr,
NULL, 0);
...
for (i = 0; i < ARRAY_SIZE(mlxplat_mux_data); i++) {
priv->pdev_mux[i] = platform_device_register_resndata(
&mlxplat_dev->dev,
"i2c-mux-reg", i, NULL,
0, &mlxplat_mux_data[i],
sizeof(mlxplat_mux_data[i]));
But actual parent of "i2c-mux-reg" device is priv->pdev_i2c->dev and
not mlxplat_dev->dev.
Patch fixes parent device parameter in a call to
platform_device_register_resndata() for "i2c-mux-reg".
It solves the race during initialization flow while 'i2c_mlxcpld.1' is
removing after probe, while 'i2c-mux-reg.0' is still in probing flow:
'i2c_mlxcpld.1' flow: probe -> remove -> probe.
'i2c-mux-reg.0' flow: probe -> ...

When a switch event, such as tablet mode/laptop mode or docked/undocked,
wakes a device make sure that the value of the swich is reported.
Without when a device is put in tablet mode from laptop mode when it is
suspended or vice versa the device will wake up but mode will be
incorrect.
Tested by suspending a device in laptop mode and putting it in tablet
mode, the device resumes and is in tablet mode. When suspending the
device in tablet mode and putting it in laptop mode the device resumes
and is in laptop mode.

asus_nb_wmi
Commit 78f3ac76d9e5 ("platform/x86: asus-wmi: Tell the EC the OS will
handle the display off hotkey") causes the backlight to be permanently off
on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).
The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
by that commit is made conditional in this commit and only enabled in
the quirk_entry structs in the asus-nb-wmi driver fixing the broken
display / backlight on various EeePC laptop models.

critclk_systems DMI table
There are several Beckhoff Automation industrial PC boards which use
pmc_plt_clk* clocks for ethernet controllers. This adds affected boards
to critclk_systems DMI table so the clocks are marked as CLK_CRITICAL and
not turned off.

table
The Lex 3I380D industrial PC has 4 ethernet controllers on board
which need pmc_plt_clk0 - 3 to function, add it to the critclk_systems
DMI table, so that drivers/clk/x86/clk-pmc-atom.c will mark the clocks
as CLK_CRITICAL and they will not get turned off.

Add support in code for the new forms of the host sleep event.
Detects the presence of this version of the command at runtime,
and use whichever form the EC supports. At this time, always
request the default timeout, and only report the failing response
via a WARN_ONCE(). Future versions could accept the sleep parameter
from outside the driver, and return the response information to
usermode or elsewhere.
