Fix bug on samus that the battery status doesn't always show on
lightbar when AC is plugged/unplugged. It doesn't show when the
battery is full is S3 or S5 because in these states we turn off
CHARGE_EN so that ACOK to the EC never toggles.
Instead, what we want to do is display battery status whenever the
active charge port changes. This will happen when AC is plugged or
unplugged OR if a user has AC on both ports and toggles between
them using the charge override hot-keys.
BUG=chrome-os-partner:36317
BRANCH=samus
TEST=test plugging and unplugging AC on both sides when battery is
full and unit is in S0, and when unit is in S5. also tested lightbar
flashes battery percentage when two zingers are plugged in and you

Occasionally the charge circuit on samus gets wedged and will not
charge. This change detects when the charge circuit has failed
and automatically recovers from it. It uses the BQ PROCHOT warning
to detect the failure by setting PROCHOT to trigger when the BQ
thinks input current is higher than the input current limit. When
the failure is detected, the EC disables charging and tells PD MCU
to disable CHARGE_EN, then a couple seconds later, it re-enables
charging.
This CL also adds more communication between EC and PD for the EC
to be able to set the charge state for the PD. Valid charge states
are: No charging allowed, 5V charging only, and max charging. The
EC uses this as such:
- When the EC gets AC present interrupt, it sets off a deferred
function to change charge state to max charging after some delay
to give time for the charge circuit to settle down.
- When the EC gets AC disconnect interrupt, it disables charging
briefly, enables learn mode, and then sets 5V charging allowed.
This allows for the same starting conditions in the charge circuit
for every AC attach.
- When the EC detects a wedged charge circuit, it disables charging
and waits a few seconds before re-enabling 5V only charging.
Additionally, this change moves the charging cutoff in S3/S5/G3 when
the battery is full to the EC. With the added control for the EC
to set the PD charging state, it is more convenient for the EC to
manage cutting off charging when battery is full.
BUG=chrome-os-partner:36081
BRANCH=samus
TEST=test the basics:
- connect/disconnect zinger a bunch of times
- connect and disconnect two zingers in different order

test the automatic charge wedge recover:
- wedge the charge circuit by setting charger voltage under battery
voltage: "charger voltage 7000"
- wait a few seconds for the system to recover and check it is charging
with "battery" command
test full battery charge cutoff:
- added console command to change battery soc in board/samus/extpower.c:
static int cmd_battfake(int argc, char **argv)
{
char *e;
battery_soc = strtoi(argv[1], &e, 10);
batt_soc_change();
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND(battfake, cmd_battfake, "", "", NULL);
- in S0, tested "battfake 100" does not disable charging.
- in G3, tested "battfake 100" disables charging and "battfake 99"
re-enables charging.
- set "battfake 100" and tested transitioning to S0 enables charging and
transitioning to S5 disables charging.
- attached two chargers and used charge override to select active port.
then toggled "battfake 100" to "battfake 99" back and forth and verified
charge override port is still the same.
test third-party 12V charger:
- plug in a bunch of times and make sure we stay at 5V for 500ms and then
transition to 12V
test with no battery:
- tested five different units with no battery and just zinger. 3/5 boot,
while the other 2 don't. But, the 2 that don't boot without battery also
can't boot w/o battery when this CL is reverted, so I don't think this
change is causing the problem, I think there is an electrical limitation.
test with EVT zinger:
- EVT zingers (P2 - C2) negotiate very quickly after connection, which
can cause INA problems w/o this CL. Tested an EVT zinger with samus and
did a bunch of connections and disconnections and verified that we always
wait at 5V for 500ms and that we don't wedge the INA circuit on connect.
test backwards compatibility:
- test new PD with old EC and make sure we can charge with zinger.
(note that if the charge circuit wedges, we won't be able to unwedge it).
- test old PD with new EC and make sure we can charge with zinger.

Most GPIO/peripheral interrupts are enabled in HOOK_INIT or some other
*_init() functions that are called before task_start(). Quite a lot of
these IRQ handler wake some task to process the interrupt, and this
causes a race condition. If the interrupt is triggered before

Fix this by only allowing rescheduling tasks if task_start() is called.

Several modifications to samus fast charging to fix bug where
charging circuit stops charging the battery.
- Fix bug: if we have a bad temperature reading, fast charging should
ignore it.
- Change the fast charging high temperature profile to set a charging
voltage equal to the maximum of 8.3V and the current battery voltage.
- Divide the normal temperature profile into two phases, low voltage
charging and high voltage charging. Once we transition to second
phase, don't allow it to go back to phase 1 unless AC is removed.
On samus, we have to make sure we never command the BQ to a charging
voltage that is below the present battery voltage or else the INA will
lose power and we will not be able to charge the battery until AC
is disconnected.
This also changes charge_state_v2 so that the fast charging profile
override is called even when AC is disconnected to avoid jumps in
temperature as seen by the fast charging code.
Also changes the voltage threshold for transitioning from phase 1 to
phase 2 of normal temp charging so that the transition is taken a little
earlier to match the desired profile slightly better.
BUG=chrome-os-partner:35491

fast charging regions and made sure that (1) we never set a charging voltage
below the present battery voltage and (2) we never stop charging the battery.

Fix bug if we are executing a power swap to a sink, and we don't
get PS_RDY from port partner, then we transition to SNK_DISCONNECTED
without switching our power role to sink, which could cause us to
get wedged in the wrong state if we also receive a hard reset a
little later because we will have Rd asserted but are will transition
to source role and can never get out of it.
BUG=none
BRANCH=samus
TEST=load onto two samus' and executing a bunch of power swaps. load
custom code on one samus to never send PS_RDY when switching from sink
to source and make sure when power swap occurs the state machine does
not get wedged with the wrong role.

The new toolchain is putting again the __enter_hibernate function in
flash (.text) rather than in SRAM (.iram.text) after inlining both the
hibernate() and __enter_hibernate() function.
Workaround this issue by forcing "noinline" on __enter_hibernate().

If the AP ignores the LPC_ST_BUSY bit (which is software-defined) and
tries to send a second host command while the first one is still
processed, we discard it.
This doesn't prevent the host to re-write the command arguments stored
in LPC shared mem (aka LPC_POOL_CMD_DATA) but when we will call
host_packet_receive, we will have either the old arguments or the new
arguments (or even a mix of both, which is less unlikely to pass the
checksum check), and we will copy them once before calling the HOSTCMD
task. So the host command task will have a single coherent (not
changing) view of the arguments when performing its input validation.

The VCC_PWRGD pin is used as an indication of VCC2 state and controls
the internal VCC_PWRGD signal. On Glower, the pin is floating so we
can't use it as is. Instead, configure the pin as a GPIO so that the

Without this, nSIO_RESET would be kept asserted and most LPC-related
