30287d4757 charger: Add CONFIG_CHARGE_STATE_DEBUG
Servo / Suzy-Q related debugging methods is a big challenge
in factory especially after servo debug header is removed.

Expose some information to OS from EC will do a great help
for massive production.

+ expose charge/battery related state to ectool
	1. chg_ctl_mode
	2. manual_mode
	3. battery_seems_to_be_dead
	4. battery_seems_to_be_disconnected
	5. battery_was_removed

6010e6c98e coral: Add support for multiple batteries
- This CL adds the infrastructre needed to support different battery
  types for the Coral project.

- This includes adding a battery_check_disconnect common function
  that's used folloiwng battery cutoff events to ensure that the
  battery is able to provide power before reporting it as present.
  When the battery is not present, there is a 1 second delay used
  before allowing the battery to report as present. This specific
  change is motivated by an issue discovered on Eve which resulted in
  H1 power rail issues and could lock up the H1.
  https://chromium-review.googlesource.com/c/592717
  https://chromium-review.googlesource.com/c/585837

- This includes a  battery_cutt_off_battery common function that can
  be used by all battery types using the register and regiseter data
  required for each battery's ship mode.

096ea20ed1 g: restore DATA PID after USB suspend/resume
In USB FS on a bulk/interrupt endpoint, the transactions normally toggles
between DATA0 and DATA1 PIDs.
After a USB suspend/resume cycle, we need to restart from the PID we
were at before suspend.
In our current code, when going to deep-sleep during USB suspend, we are
re-initializing everything when the MCU restarts at each resume. So we set
implicitly the PID to DATA0. The USB Hardware IP just silently discards the
packet when the PID of an incoming OUT packet is not matching the
expectation in the endpoint register.

In order to preserve DATA PIDS, record the state of the PID toggling on
each endpoint when going to deep-sleep and restore it during the USB
initialization.

8c9f9ad861 usb_updater: allow to communicate with cr50 using trunks_send
It is necessary to be able to access Cr50 using usb_updater without
stopping trunksd services. This patch adds another option for
usb_updater to communicate with Cr50, using the trunks_send command.

A new command line option '-t' is added to allow to choose the new
interface.

When communicating over trunks_send the same processing is used as
when communicating over /dev/tpm0, just instead of talking to the
hardware device, popen() function is used to run trunks_send --raw
command and to gain access to its console output.

f31ee0c829 servo_v4: Add a CCD 'keepalive' console command.
Servo v4 monitors the SBU lines on USB-C connects in order to determine
which direction to set the orientation of the SBU mux.  However, when
there's traffic on the lines, for example when the EC is rebooting, it
can lead to the wrong conclusions and terminate the USB connection.

This commit adds a CCD keepalive console command.

Additonally, when the Type-C cable is unplugged from the DUT for at
least 900ms, the CCD keepalive will be cleared.  This is such that if
the cable is unplugged and then replugged in a different orientation,
the detection will still work.

BUG=b:64903997

a59ea3c4db ccd: Consolidate config commands
Previously, all CCD config commands were their own distinct commands.
This led to accidental side-effects when someone would type 'ccdlock'
thinking it would print the lock state when it would actually lock the

Make them all sub-commands of 'ccd'.  So, 'ccd lock', not 'ccdlock'.
Just 'ccd' by itself will print the current config.

No changes to how the sub-commands themselves work.

a285acd36f cr50: Consolidate CCD device enable
Currently, the Cr50 state machines (EC, AP, RDD, bitbang, etc.) manage
their own enabling and disabling of the ports (UART, SPI, etc.)  This
is tricky because the rules for when ports should be enabled are
non-trivial and must be applied in the correct order.  In additionl
the changes all need to be serialized, so that the hardware ends up in
the correct state even if multiple state machines are changing
simultaneously.

Consolidate all of that into chip/g/rdd.c.  The debug command for it
is now 'ccdstate', which just prints the state machines.  This will
allow subsequent renaming of the 'ccdopen', etc. commands to 'ccd
open', etc.

Also include UART bit-banging into that state which must be
consistent.  Previously, it was possible for bit-banging to leave UART
TX connected, instead of returning it to the previous state.

Use better names for CCD config fields for UART.  I'd had them backwards.

8e6d0fb64a cr50 updater: reject images with mismatching board ID
There is no point in updating the Cr50 to an image which will not be
allowed to run due to board ID settings mismatch.

This patch modifies the prototype of check_board_id_mismatch() to
allow to pass to this function an arbitrary pointer to an image
header, so that the function can check not only the image in the flash
memory, but also the image which just arrived over the line.

The contents_allowed() function now checks if the new image is
compatible with the Board ID value in Info1 and rejects the new image
if there is a mismatch.

BRANCH=cr50
BUG=none
TEST=tried updating a Cr50 to an image which is incompatible with the
     Info1 fields contents. The update attempt is rejected. Verified
          that updating to a compatible image still works as designed.

ebe3caeb69 npcx: bypass for CSAE issue if CONFIG_LOW_POWER_IDLE is disabled
In order to prevent keeping the CSAE bit at 1 forever impacts the eSPI
performance, the npcx driver enables host access wakeup functionality
before ec enters deep sleep or wfi. But this bypass also should be added
in __idle() of core/cortex-m/task.c if CONFIG_LOW_POWER_IDLE is
disabled.

This CL also narrows the bypass only when host interface is eSPI.

functionality on poppy and use following script "count=0; while :;
do echo "--- iteration --- $count"; time flashrom -p ec -r ec.bin; sleep

times. No errors occur and all tests' efficiency are the same as
removing CSAE bypass.

ac1ce379e0 chip/g: use ccd_ext_is_enabled() instead of ccd_get_mode()
Currently, only usb_pd_protocol.c cares about the actual ccd mode
(disabled/partial/enabled).  Everything else just cares whether it's
enabled or not.  So promote the boolean ccd_is_connected() from
board/cr50 up to chip/g, and rename it to ccd_ext_is_enabled() to
match the new nomenclature (since 'CCD' itself is now too overloaded).
This will make it easier to handle CCD state directly in board/cr50
after we split it from common/case_closed_debug.c

f35ae8ab1c scarlet: Initialize non-PD/USB-C charge suppliers
Before all of the charge suppliers are initialized,
charge_manager_refresh() wouldn't be called to update
charging voltage/current.
Since we don't define CONFIG_USB_CHARGER, we need
to do the initialization in board specific files.

BUG=b:65118519
BRANCH=none
TEST=manually verify charging voltage/current are updated

17150b05ff cr50: Split AP state machine into its own file
The device state machines aren't quite similar enough to use common
code.  Split the AP state machine out, the way we split out the EC
state machine in the previous CL.

BUG=b:35587387
BRANCH=cr50
TEST=manual, with Cr50 strapped (or hard-coded) not to use platform reset
     and not to use TPM reset to detect the AP:
        Pull CCD_MODE_L low, so Cr50 detects/enables CCD
        Pull AP_DETECT high.
	Pull INT_AP_L low (with resistor).

        Pull AP_DETECT low --> See 'AP off' message
	gpioget --> INT_AP_L=0
        ccd --> AP UART disabled

        Pull AP_DETECT high --> See 'AP on' message
	gpioget --> INT_AP_L=1
        ccd --> AP UART RX+TX

        Pull AP_DETECT low for <1 sec then back high
        (don't see AP off/on message)
	gpioget --> INT_AP_L=1
        ccd --> AP UART RX+TX

	Reboot with AP_DETECT still low -> AP off at 1 second

	Reboot with AP_DETECT still low and then assert AP_DETECT
	within a second -> AP on immediately

	Repeat with Cr50 strapped/hard coded to use platform reset, but
	using TPM_RST_L instead of AP_DETECT.  Note that this will also
	show TPM reset debugging output when TPM_RST_L is asserted.

8202ddaa95 cr50: Only enable UART RX when EC/AP is on
Previously, some code paths such as CCD permissions change could
result in enabling EC or AP UART RX when the EC or AP is off.  This
could result in interrupt storms.

b52f9b8ea6 sensors: Support device with only one accelerometer
LPC area for sensors support 3 sensors:
up to 2 accelerometers and 1 gyro.

If only 1 accelerometer is present, only the first accelerometer slot is
populated.
If there is no gyro, the gyro slot is not populated.

Add tests and remove assumption in the code to be sure the rules above
are enforced.
