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.

With only four LED segments, it's confusing to indicate a power
percentage by dimming the top segment unless you can see the
indicator smoothly ramping up from all-off. This does that.
Kind of pretty, if I say so myself.

Run "ectool lightbar demo on", then press the T key to invoke the
pattern and the arrow keys to fake the charge state.

The PD task is using more space in the stack and I'm seeing frequent
stack overflow on Plankton. On Samus, we already increased the stack
size. Let's also increase this on Ryu and Plankton.

Implemented source recovery time following a hard reset. According
to the spec:
After a hard reset, the source must dissipate output voltage
to vSafe5V. After establishing the safe voltage condition on VBUS,
the power supply shall wait tSrcRecover before powering VBUS to
vSafe5V.
BUG=none

TEST=plug in a type-c to type-a adapter to samus. then issue a hard
reset from the console and verify that it takes nearly a second before
samus re-enables vbus.

For a sink, when there is no source cap packet within SinkWaitCapTimer,
then it sends a hard reset. Once the hard reset has been retried
nHardResetCount times then it shall be assumed that the remote
device is non-responsive, and we stop sending the hard reset.

Add support for enabling Vconn on Raiden ports by defining
CONFIG_USBC_VCONN. This is enabled by default for ryu, samus,
and fruitpie.
BUG=chrome-os-partner:30445
BRANCH=samus
TEST=Load onto samus. Make sure we can still charge from zinger.
Plug in type-A to type-C adapter with pulldown and see that samus
becomes power source. Do a gpioget and verify that only one VCONN
GPIO is enabled (low), and the VCONN that is enabled is opposite of
the polarity queried by pd 1 state. Try both ports, both polarities
and make sure the correct VCONN gpio is enabled.
