After ChromiumOS CL:1293132 and CL:1295890, Chrome EC can store the flag
telling if the last reboot was triggered by AP watchdog for some boards
(e.g., Kukui).
This CL adds a new function google_chromeec_get_ap_watchdog_flag(),
which reads the AP watchdog flag from Chrome EC, and updates the tables
of reset causes and reset flags.
A new Kconfig option CHROMEOS_USE_EC_WATCHDOG_FLAG is added for
elog_handle_watchdog_tombstone() to determine if watchdog reset was
triggered by the AP watchdog flag from EC instead of the tombstone in
AP.

perform power and data role swap.
This change is split across the DSDT and SSDT, with the shared
memory and operation region declared in the SSDT after being
allocated in CBMEM.
The OS will fill in the registers in the system memory region and
then call the _DSM method wtih a read or write argument. The DSM
method will copy the required registers to/from the system memory
and the EC and perform the write or read action.
Responses from the EC will generate a new SCI with event code 0x79
which will notify this UCSI ACPI device and the OS driver will take
action to read status from the EC.

Commit 8cf8aa2 [ec/google/chromeec: Use common MEC interface]
changed the return mechanism for the checksum on reads/writes
for MEC devices, but incorrectly handled the passed-in csum
parameter by not dereferencing. This led to the returned csum
value always being zero, which causes all EC commands with non-
NULL data_in to fail with a checksum error.
Fix this by storing the returned checksum in a temp variable,
and only assigning to csum when the pointer isn't NULL;
Test: build/boot google/chell, verify EC hello command succeeds,
keyboard backlight turned on at boot.

configuring it as edge-triggered on the host results in host missing

because Linux kernel driver reads one event per irq and the EC does
not de-assert the interrupt line until all events are drained
out. This results in event queue being filled up completely on the EC
and the host failing to see any of those events.

If remaining charge is more than x% of the full capacity, the
remaining charge is raised to the full capacity before it's
reported to the rest of the system.
Some batteries don't update full capacity timely or don't update it
at all. On such systems, compensation is required to guarantee
the remaining charge will be equal to the full capacity eventually.
On some systems, Rohm charger generates audio noise when the battery
is fully charged and AC is plugged. A workaround is to do charge-
discharge cycles between 93 and 100%. On such systems, compensation
was also applied to mask this cycle from users.
This used to be done in ACPI, thus, all software components except EC
was able to see the compensated charge. This patch is part of the
effort of moving the logic to EC. With this and the EC changes, EC
can see what the rest of the system sees, thus, can control LEDs
synchronously (to the display percentage).
Another rationale of this move is EC can perform more granular and
precise compensation than ACPI since it has more knowledge about the
battery and the charger.

This includes the EC device and its resources, as well as the layout

The EC RAM address space is typically read/write, and so the ACPI EC
device expects that a defined Field can be read and/or written. With
this EC the read and write address spaces are different. For example,
a read from address zero will return data that is unrelated to what a
write to address zero expects.
This makes using a typical OperationRegion to describe the EC RAM
address space somewhat impracticle, since field definitions would
overlap. Instead, methods are provided for reading and writing to an
EC RAM offset, and the EC RAM layout is defined as a Package that
describes offset+mask for read or write fields within the EC RAM.

Some boards are adding a second pin used for synchronization between

Currently the runtime EC interrupts assert an SCI before eventually
resulting in a Notify() on the MKBP device that the sensor driver users.
These extra layers add processing time and require additional EC
communication to determine the event source.
This interface was tested on a reworked Nocturne board with modified
EC and a modified kernel driver to ensure that the interrupt asserts

Some ACPI interfaces introduced by Chrome or coreboot do not
need drivers outside ChromeOS, for example Chrome EC or
coreboot table; or will be probed by direct ACPI calls (instead
of trying to find drivers by device IDs).
These interfaces should be set to hidden so non-ChromeOS systems,
for example Windows, won't have problem finding driver.
Interfaces changed:
- coreboot (BOOT0000), only used by Chrome OS / Linux kernel.
- Chrome OS EC
- Chrome OS EC PD

Currently, google_chromeec_pd_get_amode infinitely loops if a TCPC port
is connected to a device with alternate mode(s) and the call is made
for the mode with the index higher than 0 (e.g. Zinger).
Cros EC manages alternative modes entered in an array (amode[]). The
command is designed to accept a query for an particular index and a
particular SVID.
Zinger has a 'Google' mode. It's stored in amode[0]. When AP queries
first time for DisplayPort with index=0, EC says 'no' as expected.
AP sends the next query with index=1 but EC_CMD_PROTO_VERSION (0x00)
is sent instead because cmd_code is cleared by google_chromeec_command.
res.svid is supposed to be 0 when EC hits the last index + 1 but
res.svid is set to 2 by the EC_CMD_PROTO_VERSION handler because
EC_PROTO_VERSION is currently 2. So, the call succeeds and AP goes to
the next index and this repeats forever.
Any USB-C device with non-DisplayPort alternate mode can cause this
hang unless HDMI port is used.
This patch resets all the fields of chromeec_command in each iteration
in case google_chromeec_command changes them.

Some type-c monitors do not immediately assert HPD. If we continue
to boot without HPD asserted, Depthcharge fails to show pictures
on a monitor even if HPD is asserted later.
Also, if an HDMI monitor is connected, no wait is needed. If only
an HDMI monitor is connected, currently the API always loops until
the stopwatch expires.
This patch will make the AP skip DisplayPort wait loop if it detects
an HDMI monitor. And if an HDMI monitor is not detected, the AP will
wait for DisplayPort mode (like before) but also its HPD signal.
This patch also extends the wait loop time-out to 3 seconds.

Unified Host Event Programming Interface (UHEPI) enables a unified host

Old host event commands (0x87, 0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E,
0x8F) is supported for backward compatibility. But newer version of
BIOS/OS is expected to use UHEPI command (EC_CMD_PROGRAM_HOST_EVENT)
The UHEPI also enables the active and lazy wake masks. Active wake mask
is the mask that is programmed in the LPC driver (i.e. the mask that is
actively used by LPC driver for waking the host during suspended state).
It is same as the current wake mask that is set by the smihandler on host
just before entering sleep state S3/S5. On the other hand, lazy wake masks
are per-sleep masks (S0ix, S3, S5) so that they can be used by EC to set
the active wake mask depending upon the type of sleep that the host has
entered. This allows the host BIOS to perform one-time programming of
the wake masks for each supported sleep type and then EC can take care
of appropriately setting the active mask when host enters a particular
sleep state.

consistent view, host should clear all MKBP events in the FIFO if host
event is being cleared.
This change drains out all the MKBP events in the FIFO when
clear_pending_events is called.
TEST=Verified by adding debug logs in EC to verify that all the MKBP
events that occur before clear_pending_events is called get cleared
from the FIFO.

This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.
If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.
This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.
Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.
The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.
Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.
Patched with Coccinelle using the clumsy spatch below and some manual
changes:
* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.
