The cannonlake power state chipset code would fail to keep an accurate

that the AP was in G3, whereas the SLP_SUS_L signal was deasserted.
This commit fixes a few issues with the chipset code.
- First, don't have PP3300_DSW_EN enabled by default coming out of
reset.
The default chipset power state when the EC comes out of reset is G3,
therefore we should not enable the PP33000 DSW rail until we decide to
leave G3. This is usually triggered by a power button press.
- Similarly, when we wish to enter G3, we should turn off the PP3300 DSW
rail instead of the noop that was done before.
- Lastly, turn on the 5V rail when entering S5 instead of S3 and turn it
off when leaving S5 to G3.

is the mask that is programmed in the LPC driver (i.e. the mask that is

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

There is a fundamental difference in host behavior w.r.t. S3 and
S0ix. When the host enters S3, it asserts the SLP_S3# signal until it
is woken back up. Thus, EC depends on the SLP_S3# signal state to
decide when to notify listeners about CHIPSET_SUSPEND and
CHIPSET_RESUME state.
With S0ix, SLP_S0# signal is asserted whenever host enters
S0ix. However, periodically (every 8 seconds), the host wakes up for
some bookkeeping activities, but does not come out of the low power
mode completely. This bookkeeping activity takes ~2-5 ms and the host
goes back into S0ix state. Because of this periodic activity, SLP_S0#
signal is de-asserted and asserted back every 8 seconds.
Thus, if the power state machine depends solely on the SLP_S0# signal
to notify CHIPSET_SUSPEND and CHIPSET_RESUME states, then all the
listeners would be performing unnecessary actions every 8
seconds. This leads to a number of side-effects including:
1. Dual-role toggle being enabled and disabled every 8 seconds.
2. Power spikes in EC power consumption during S0ix every 8 seconds.
In order to avoid the side-effects of periodic host activity in S0ix,
this change adds a new flag s0ix_notify, which is set based on the
notifications that are pending based on host sleep event.
On receiving host sleep event for S0ix suspend, s0ix_notify will be
set to S0IX_NOTIFY_SUSPEND. Next, whenever SLP_S0# is asserted,
power_state machine notifies listeners of CHIPSET_SUSPEND
and resets s0ix_notify flag to S0IX_NOTIFY_NONE. Thus, all future
assertions of SLP_S0# do not result in the suspend notification.
Similarly, on resume, power_state machine will not notify
CHIPSET_RESUME on SLP_S0# deassertion. Instead the host sleep event
for S0ix resume will set s0ix_notify flag to S0IX_NOTIFY_RESUME and
wake chipset task. The power state machine in turn will notify
listeners of the resume event and reset s0ix_notify flag.

Instead of clearing out all the host events on S0ix wake, provide an
opportunity to the host to read the events and log it. Move the call
to clear events to the point where host sends a command indicating
exit from S0ix.
BUG=b:67874513
BRANCH=None
TEST=make -j buildall. Verified that host events are cleared by the
host during logging.

Instead of duplicating the handling of host events and host event
masks in chip lpc drivers, add routines in common code to provide
basic functions like setting/getting of masks, setting/getting of
events and handling of masks transitions across sysjump.
BUG=None
BRANCH=None
TEST=make -j buildall. Verified following:
1. Event masks are correctly retained across sysjumps.
2. Wake from S3 works fine.
3. Wake from S0ix works fine.
4. SCI generated correctly.

Runtime S0ix results in SLP_S0 signal being toggled continuously
resulting in an interrupt storm on the EC. In order to avoid this,
enable SLP_S0 power signal only when host indicates intent to enter
S0ix and disable when host exits from S0ix.
BUG=b:65421825
BRANCH=None
TEST=Verified that runtime S0ix no longer results in interrupt storm
on EC. Normal S0ix works fine on soraka. Verified state of SLP_S0

Replace structure member "level" in power_signal_info with "flags".
"level" has been used on all boards to indicate active-high or
active-low levels. Addition of "flags" allows easy extension of
power_signal_info structure to define various flags that might be
applicable to power signals (e.g. "level"). Going forward, additional
flag will be added in follow-up CLs.
Also, provide a helper function power_signal_is_asserted that checks
the actual level of a signal and compares it to the flags level to
identify if a power signal is asserted.

On proto3, PMIC isn't powered on POR, thus board_pmic_init fails.
With this change, EC waits until AP power is ready before it
notifies HOOK_CHIPSET_PRE_INIT where PMIC will be initialized.
When AP power is ready, PMIC should be ready as well.
