x86 devices use TPM_RST_L to detect the AP state, so we set
device_states[DETECT_AP].detect to GPIO_TPM_RST_L on those boards.
board_update_device_state uses this signal to poll the AP state once a
second to detect if the device is off.
If for some reason TPM_RST_L is deasserted, but the tpm reset handler
has not yet set the state to 'on', we will catch it when we poll the AP
state with board_update_device_state. It will call device_state_on with
TPM_RST_L. In that case device_state_on used to silently disable the
TPM_RST_L interrupt and not change the AP state. This change modifies
device_state_on to notify the tpm reset handler and prevent it from
disabling the tpm reset interrupt.

This patch adds a host command to get PD chip info.
For PS8751, tcpci_get_chip_info will fail if the chip is in
low power mode. It can be woken up by reading a random register
first then wait for 10ms.
This code doesn't have the wake-up read to avoid 10ms delay.
Instead, we call this function immediately after the chip is
initialized because it'll gurantee the chip is awake.
Once it's called, the chip info will be stored in cache, which
can be accessed by tcpc_get_chip_info without worrying about
chip states.

both ways by using the `wp` console command. A user can either force
write protect enabled or force write protect disabled. Additionally,
the behaviour can be reset to follow the state of the battery pin by
issuing `wp follow_batt_pres`. However, the ability to force the write

In case there is a sudden power loss to PCH, then there are no eSPI VW
messages sent from the PCH to EC indicating power state transition into
S5. Instead, the eSPI compatibility spec defines such events as global
reset events. For global reset events, eSPI_Reset# signal is asserted
without SLP_SUS# being asserted. This acts as an indication to the EC
that there was a global reset event.
Add a callback chipset_handle_espi_reset_assert that takes any necessary
action whenever eSPI_Reset# pin is asserted. On skylake, it would check
if power button was being pressed and release the button.

The cr50 needs to be aware of the power state of the system and of the
moment when the AP is reset, because this is when the TPM needs to be
reset too.
Arm and x86 platforms provide different hints in these cases.
In case of x86 there is a single signal cr50 can rely on: PLT_RST_L.
This active low signal is asserted when the system is going into any
power state deeper than s0ix. The cr50 can fall into deep sleep when
PLT_RST_L is asserted, and has to wake up and reset the TPM when this
signal is deasserted. There could be other wake triggers, but the tpm
should not be reset unless PLT_RST_L is inactive. It is also important
not to fall into deep sleep when PLT_RST_L is pulsed to reboot the
system.
In case of ARM there are two separate signals. Deasserting SYS_RST_L
signal is the trigger to reset the TPM, The GPIO_DETECT_AP going low
for a duration of time is the indication of the AP going into some
kind of sleep mode. The ARM case requires more clarification.
This adds run time configuration of the the sleep state control input.
Once the input turns low, the CHIPSET_SHUTDOWN signal is sent and deep
sleep mode is enabled. Again, this will require adjustment for ARM
platforms.
The wake from deep sleep state is controlled by the wake pins as
before, but by level instead of edge. This makes sure that in case the
trigger for deep sleep goes away while deep sleep preparation is under
way, the device resumes immediately instead of getting stuck missing
the edge.
The TPM_RST_ input is now triggering interrupts on deassertion
- this is the moment when the TPM needs to be reset. The ISR is being
renamed accordingly.
The processing previously happening inside the ISR is being moved into
a deferred function running on the hooks task context.
There is no need to invoke TPM reset related functions from the PMU
wake up ISR anymore.

The INAs are only used for development and testing
purposes. Therefore, the 3.3V rail to the INAs is off by default and
the I2Cm module is not enabled. Enabling INA power and connecting the
I2Cm module was done at the beginning of each USB to I2C request. The
problem with this approach is that INA measurments didn't always
succeed due to not enough time for the INAs to initialize.
Rather than add some arbitrary delay, it is better to tie the INAs to
when rdd is attached/detached. It is only when rdd is attached that
the INAs will be accessed, so there is no need to enable/disable for
each individual I2C transaction.
This CL ties the enabling/disabling of the INA and I2Cm module to the

The output of pinmux command is garbled (it probably was OK until the
console UART TX buffer was significantly reduced in size by
https://chromium-review.googlesource.com/418948).
Let's flush the console every so often.
Also, fixed the bug where the second GPIO port base address in PIMUX
was off, and added a newline to separate UART section of the output.
BRANCH=none
BUG=none
TEST=ran pinmux command successfully. make -j buildall passes

During shutdown sequence sensor rails can be powered down asynchronously
to the EC hence EC cannot interlock the sensor states with the power down
states. To avoid this issue, defer switching the sensors rate with a
configurable delay if in S3. By the time deferred function is serviced,
if the chipset is in S5 we can back out from switching the sensor rate.
BUG=chrome-os-partner:61489
BRANCH=none
TEST=Manually tested on Electro. Put the device in S5 and observed
no I2C errors printed on EC the console.

charge_ramp needs to make a decision based upon the VBUS level on one
specific port - the port that is ramping. The VBUS level on any other
charge ports (if present) is not relevant.
BUG=chrome-os-partner:54099
BRANCH=reef, gru
TEST=With subsequent patches, verify charge_ramp success with a variety
of BC1.2 chargers.

The commit changes the behaviour to block accesses over the USB-SPI
bridge while the console is restricted.

using CCD. Verify that it fails with flashrom not able to find a flash
chip.

Previously, and invalid strap configuraiton was not updating the copy
in the long life register. Since we don't expect to have invalid strap
pins, but if they are read, it's not expected to change run to
run. Therefore, to have consistent behavior, store the properties
determined in the long life register in all cases.

Tested with Reef/Gru which both have valid table entries and verified
that board properties were being saved in the long life
register. Tested on Eve which has currently an invalid strap config
and repeated the test.
