e8bf17d58a platform/chrome: cros_ec: Expose suspend_timeout_ms in debugfs
In modern Chromebooks, the embedded controller has a mechanism where
it will watch a hardware-controlled line that toggles in suspend, and
wake the system up if an expected sleep transition didn't occur. This
can be very useful for detecting power management issues where the
system appears to suspend, but doesn't actually reach its lowest
expected power states.

Sometimes it's useful in debug and test scenarios to be able to control
the duration of that timeout, or even disable the EC timeout mechanism
altogether. Add a debugfs control to set the timeout to values other
than the EC-defined default, for more convenient debug and
development iteration.

affc804c44 platform/chrome: cros_typec_switch: Add switch driver
Introduce a driver to configure USB Type-C mode switches and retimers
which are controlled by the ChromeOS EC (Embedded Controller).
This allows Type-C port drivers, as well as alternate mode drivers to
configure their relevant mode switches and retimers according to the
Type-C state they want to achieve.

ACPI devices with ID GOOG001A will bind to this driver.

Currently, we only register a retimer switch with a stub set function.
Subsequent patches will implement the host command set functionality,
and introduce mode switches.

f74c7557ed platform/chrome: cros_ec_proto: Update version on GET_NEXT_EVENT failure
Some EC based devices (e.g. Fingerpint MCU) can jump to RO part of the
firmware (intentionally or due to device reboot). The RO part doesn't
change during the device lifecycle, so it won't support newer version
of EC_CMD_GET_NEXT_EVENT command.

Function cros_ec_query_all() is responsible for finding maximum
supported MKBP event version. It's usually called when the device is
running RW part of the firmware, so the command version can be
potentially higher than version supported by the RO.

The problem was fixed by updating maximum supported version when the
device returns EC_RES_INVALID_VERSION (mapped to -ENOPROTOOPT). That way
the kernel will use highest common version supported by RO and RW.

a10fba0377 virtio: find_vqs() add arg sizes
find_vqs() adds a new parameter sizes to specify the size of each vq
vring.

NULL as sizes means that all queues in find_vqs() use the maximum size.
A value in the array is 0, which means that the corresponding queue uses
the maximum size.

In the split scenario, the meaning of size is the largest size, because
it may be limited by memory, the virtio core will try a smaller size.
And the size is power of 2.

d60b6b0bc0 Merge branch 'acpi-bus'
Merge ACPI device object management changes for v5.20-rc1.

 - Use the facilities provided by the driver core and some additional
   helpers to handle the children of a given ACPI device object in
   multiple places instead of using the children and node list heads in
   struct acpi_device which is error prone (Rafael Wysocki).

 - Fix ACPI-related device reference counting issue in the hisi_lpc bus
   driver (Yang Yingliang).

 - Drop the children and node list heads that are not needed any more
   from struct acpi_device (Rafael Wysocki).

 - Drop driver member from struct acpi_device (Uwe Kleine-König).

 - Drop redundant check from acpi_device_remove() (Uwe Kleine-König).

40ec787e1a platform/olpc: Fix uninitialized data in debugfs write
The call to:

	size = simple_write_to_buffer(cmdbuf, sizeof(cmdbuf), ppos, buf, size);

will succeed if at least one byte is written to the "cmdbuf" buffer.
The "*ppos" value controls which byte is written.  Another problem is
that this code does not check for errors so it's possible for the entire
buffer to be uninitialized.

Inintialize the struct to zero to prevent reading uninitialized stack
data.

Debugfs is normally only writable by root so the impact of this bug is
very minimal.

  Probing and removing are invoked by hotplug events raised upon line

c9d959fc32 platform/x86: pmc_atom: Match all Lex BayTrail boards with critclk_systems DMI table
The critclk_systems[] DMI match table already contains 2 Lex BayTrail
boards and patches were just submitted to add 3 more entries for the
following models: 3I380NX, 3I380A, 3I380CW.

Looking at: https://www.lex.com.tw/products/embedded-ipc-board/
we can see that Lex BayTrail makes many embedded boards with
multiple ethernet boards and none of their products are battery
powered so we don't need to worry (too much) about power consumption
when suspended.

Add a new DMI match which simply matches all Lex BayTrail boards and drop
the 2 existing board specific quirks.

The warning happens when CONFIG_CROS_EC is set but CONFIG_OF is not set.
Reproduce:
- mkdir build_dir
- wget [1] -O build_dir/.config
- COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross W=1 \
  O=build_dir ARCH=s390 SHELL=/bin/bash drivers/platform/chrome/

Fix the warning by using __maybe_unused.  Also use IS_ENABLED() because
CROS_EC is a tristate.

74bed42fd5 platform/chrome: cros_ec_proto: add Kunit tests for cmd_xfer_status
cros_ec_cmd_xfer_status() calls cros_ec_cmd_xfer() and cros_ec_map_error().

Given that there are already test cases for cros_ec_cmd_xfer(), only add
basic Kunit tests for cros_ec_cmd_xfer_status().

3e1c715ea1 platform/chrome: cros_ec_proto: return -EPROTO if empty payload
cros_ec_wait_until_complete() sends EC_CMD_GET_COMMS_STATUS which expects
to receive sizeof(struct ec_response_get_comms_status) from
cros_ec_xfer_command().

Return -EPROTO if cros_ec_xfer_command() returns 0.

While EC_COMMS_STATUS_PROCESSING flag is still on after it tries
EC_COMMAND_RETRIES times for sending EC_CMD_GET_COMMS_STATUS,
cros_ec_wait_until_complete() doesn't return an error code.

Return -EAGAIN in the case instead.

0aad9aff6a platform/chrome: cros_ec_proto: separate cros_ec_wait_until_complete()
EC returns EC_RES_IN_PROGRESS if the host command needs more time to
complete.  Whenever receives the return code, cros_ec_send_command()
sends EC_CMD_GET_COMMS_STATUS to query the command status.

Separate cros_ec_wait_until_complete() from cros_ec_send_command().
It sends EC_CMD_GET_COMMS_STATUS and waits until the previous command
was completed, or encountered error, or timed out.

cros_ec_send_command() has extra logic to handle EC_RES_IN_PROGRESS.
Separate the command transfer part into cros_ec_xfer_command() so
that other functions can re-use it.

Instead of using manually managed altmode structs, register the port's
altmodes with the Type-C framework. This facilitates matching them to
partner altmodes later.
