0df89000a5 pd: add a connection flag to pd port info for host
Export what the PD protocol stack thinks about the port connection
state. This simplifies getting a meaningful data role/power role from the
host (eg we are not really a UFP if we are simply dual-role toggling but
not connected).

Do not increment the command version as this is mostly
backward-compatible and currently no client actually uses that field.

6ee7b1e34e ACPI: Support accessing memmap data over ACPI CMD / DATA ports
Some platforms are unable to access the 900h-9ffh region over LPC and
must instead access memmap data through the ACPI CMD / DATA ports. To
avoid racing with data updates, disallow changes to multi-byte memmap

Linux currently enables burst mode when accessing multi-byte data and
disables it immediately afterward, though the ACPI spec defines burst mode
in a more general way.

6aebf13a6b Add CONFIG_FLASH_PSTATE option to enable persistent flash WP state
Previously, the flash module assumed it needed to emulate a SPI write
protect register using a bank of flash to hold the persistent flash
write protect state.  This is not true for mec and ncpx chips under
development, which use external SPI flash.  So, gate that code with
CONFIG_FLASH_PSTATE.  For compatibility, leave it on by default (as we
do with CONFIG_FLASH_MAPPED).

There is no change to the behavior of currently supported chips, since
all of them already assume pstate is present.  Removing this feature
from npcx will be done in a subsequent change.

02d0ce1526 samus: panic reboot EC if PD MCU crashes
Use the EC to check if PD MCU has crashed. The EC knows this
by checking the PD status bits: if PD MCU was in RW, and is
now in RO, AND it did not get to RO via a sysjump, then it
must have crashed. When the EC detects this, the EC will also
panic and reboot the entire system, so that we can software
sync to a known good state.

Also, when EC panics due to PD crash, it will log panic info.

fd9dd63e5c samus: automatically recover from charge circuit failures
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
- connect two zingers and charge override between the two

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.

17f68998fb pd: Allow multiple mode entry.
Current simplified implementation allows single mode entry.  Specification
allows multiple mode entry and its advantageous for things like flashing RW
while staying in DisplayPort mode on video dongles.

CL adds capability on DFP to track as many alternate modes as supported by the
DFP.  Initial mode entered is still the default supported mode ( 1st entry, 1st
opos).  Policy manager can then use host command, EC_CMD_USB_PD_SET_AMODE, to
enter additional supported modes.

On the UFP (hoho, dingdong) a small modification to track multiple svid mode
entries was made.

a5a2b263f8 pd: Return immediately to host from erase RW.
With CL:
 5ef45ad pd: Add timeout for HC flash commands.

I thought I'd licked the timeout related issues with flashing dingdong
& hoho.

With further testing however I found I was occassionally hitting the
failure where I couldn't return from 'flash erase' on PD peripheral
prior to the 1 second limit for host command timeout.

That could be remedied by retrying the erase on the host side which
then succeeds quickly.  That solution seems non-optimal however.
Additionally, even when erase does succeed in <1sec we have the shared
i2c bus pending.  That too is non-optimal.

For those reasons I've decide to return immediately from flash erase
command and instead put the burden of waiting the necessary time on
the host which at least does have some wider perspective on what the
system is attached to and doing.

CL also adds following related changes:
  1. corresponding ectool edit to delay 3sec after RW erase.
  2. fixup to error returns from hc_remote_flash for timeouts.

MOTIONSENSE_CMD_DUMP is deprecated, replaced with MOTIONSENSE_CMD_GET_DATA
Also use vector_3_t instead of x,y,z

ectool motionsense commands only work with newer firmware, to
handle a dynamic number of sensors.
- The host sends the number of sensor it has allocated space for.
- If 0, the EC just sends the number of sensors available
- Otherwise returns sensor information up to the limit imposed by the host.

Remove MOTIONSENSE_GET_STATUS: not needed. It is only useful for LPC,
to guarantee atomicity of the data.

f36a859e06 samus: new algorithm for tmp006 object temperature
The original algorithm is given in the TMP006 User's Guide
(SBOU107.pdf). The algorithm we previously implemented is that,
plus some additional and completely undocumented massaging of the
Tdie and Vobj registers. The original meaning of that hack is now
lost in the mists of time, thanks to our email retention policy.

This CL introduces a new algorithm variant, but at least this
time the details are in the bug report. It's essentially the same
as the User's Guide algorithm, except that we apply one-stage FIR
filters to the Tdie input and the Tobj output.

There are five new parameters: d0, d1, ds, e0, e1. Refer to
tmp006_read_object_temp_k() in ec/driver/temp_sensor/tmp006.c to
see how these new parameters are applied.

CAUTION: The tmp006 sensor algorithm is mostly math and magic
numbers. The spreadsheet attached to the bug report has six
sheets with wildly varying values for those parameters. Since the
correct parameter values haven't yet been determined for Samus,
all I can be sure of with this CL is that it seems to work and
isn't any worse than the old one.

Oh, and note that the EC's 't6cal' console command has been
disabled until/unless we add support for floating point IO. Use
ectool from the host to get and set the params instead.

    e0  1.000000e-01
    e1  9.000000e-01
  localhost ~ #

If the s0 param is zero, this sensor is uncalibrated. The params
are entered in the order in which they're displayed You can
change any or all of the parameters. Skip the ones you don't want
to update by specifying '-' for its position. (Note: throw in an
extra '--' first so that ectool doesn't think that negative
numbers are command options).

For example, to change s0 and b0:

  localhost ~ # ectool -- tmp006cal 5 1.0 - - -3.0
  localhost ~ #
  localhost ~ # ectool tmp006cal 5
  algorithm:  1
  params:
    s0  1.000000e+00
    a1  1.750000e-03
    a2  -1.678000e-05
    b0  -3.000000e+00
    b1  -5.700000e-07
    b2  4.630000e-09
    c2  1.340000e+01
    d0  2.000000e-01

    e0  1.000000e-01

7b305b752b zinger: samus_pd: increment zinger hardware id minor revision
Add a minor revision to the PD device hardware ID field in the info
custom VDM and set increment this minor ID from 0 to 1 for zinger.
This differentiates zingers for the auto-update payload, so we can
update only those with a specific major and minor ID version.

BUG=none
BRANCH=samus
TEST=load onto samus and zinger. when connect zinger, see on PD
console: Dev:0x0401 SW:2289 RW:0, which shows the appropriate
device ID.

fa4407c11c charge_state_v2: Send host event if charge state changes
If there is any delay between AC status and the battery charge status
it is possible for the power_manager to read the battery state when
the AC status event is sent and still see that the battery is not
yet charging.  This can cause lag in the UI battery icon because the
AP is not notified when the battery charge state changes.

In order for the host to be able to differentiate the dynamic battery
state changing (re-read ACPI _BST by sending Notify 0x80) from the
static battery info (re-read ACPI _BIX/_BIF by sending Notify 0x81)
it needs a separate host event.

BUG=chrome-os-partner:32196
BRANCH=samus
TEST=Test AC instertion and removal while watching state on the host
to ensure that an event is sent to the host which triggers power
manager to re-read the battery status and notice that the charge
state has changed if there is any delay after the AC status event:

watch -n 0.1 "cat /sys/class/power_supply/AC/online;
cat /sys/class/power_supply/BAT0/status;
tail -10 /var/log/power_manager/powerd.LATEST"

fb5ff7b1bb lightbar: add seq type PROGRAM for user-programmable sequences
This diff allows the user to send small programs to the EC and
gain control of the lightbar. Right now, this is only exposed
through ectool, and sysfs support will come later.

To send a program to the EC, use
$ ectool lightbar program /path/to/program.bin
and then start running the program with
$ ectool lightbar seq program

BUG=None
BRANCH=ToT
TEST=Using the above steps with hand-assembled programs.
  Checked that infinite bytecode loops do not hang the EC.
  Checked that bad opcodes exit with an error.
  Stress tested pushing programs and changing sequences.

5bc3dc3bbe samus: add automatic retries for host commands from EC to PD
Add three retries for EC to PD host commands. With this change,
removed retry mechanism in host_command_pd.c which was a retry
only for the specific EC_CMD_PD_EXCHANGE_STATUS host command.

BUG=chrome-os-partner:32006
BRANCH=none
TEST=Loaded EC code onto samus. Added the following code
for testing failed host commands to samus_pd common/host_command.c
host_command_task():
if ((evt & TASK_EVENT_CMD_PENDING) && pending_args) {
	if (i++ != 4)
		pending_args->result =
			host_command_process(pending_args);
	else {
		pending_args->result = -7;
		i = 0;
	}
	host_send_response(pending_args);
}
This test code on samus_pd drops one in every five host commands.

With this code, from the EC, I send "pdcmd 0 0", and verified that
1 out of 5 times the EC prints a host command failed code, but then
retries successfully.
