This provides a framework for additional work. It
exposes an API (ccd_set_mode) that can be used by the
PD code to enable Case Closed Debug. Enabling CCD will
result in the USB 2.0 lines on Ryu (proto 2) to be

Previously enabling USB would automatically (using an

take over the GPIO lines assigned to the USB module.
This is not OK on Ryu for Case Closed Debug because it
interferes with the AP's access to the USB 2.0 lines
even when not in Case Close Debug mode.
This change adds a configuration option to inhibit this
default initialization of the USB peripheral. It also

Previously the USB RAM size was off by a factor of two
for chips that required 32-bit alignment of accesses,
even though the underlying memory was 16-bits in size.
This change adds an additional configuration for the
access size (it still assumes that the underlying memory
is 16-bits in size) and uses that to adjust the USB_RAM
memory section in the linker scripts.
This change also removes the default values for the USB
RAM from stm32/config_chip.h because they mask issues
when new chips are added. It is better for a new chip
to fail to compile until these values are provided.
Finally, this change introduces a common USB API header

Previously the version string was special cased in the USB stack
because the build system prevented the inclusion of ec_version.h in
any file other than common/version.c. This lead to common/version.c
being the only place that the USB version string could be computed
and thus the special case of filling in the version string descriptor
at run time. This made the USB stack more complex, and lead to the
common/version.c file including usb.h, which is actually STM32
specific.
Now, the portion of ec_version.h that is deterministic is only
updated when something in the tree actually changes (by way of a
conditional in the makefile), and ec_version.h no longer has to
depend on all object files (other than the special version.o).
This allows anyone to include ec_version.h as needed. In particular,
each board that wants to define a USB version string can directly
include ec_version.h and do so.

Updating the fan speeds according to the manufacturer's specs.
The fan vendor recommends that the minimum fan speed be a 20%
duty cycle. Since the built-in fan controller has a tach-based
feedback loop, I'm using the RPM value instead of the duty cycle
(20% is 2286 RPM, according to the vendor).
The vendor also wants a 30% duty cycle to start turning, but the
built-in fan controller provides support for fast-start too. The
controller's minimum fast-start duty cycle is 50%, but it also
has a programmable number of revolutions that it will wait before
backing off.
Holding my ear down close to the fans while they start and stop,
it seems that the minimum 2 revolution start period is sufficient
and provides the least noise. Of course, since I've never had any
problems starting the fans directly at 1000 RPM this noise is a
little more noticeable than that. It's quite possible that the
built-in controller is smart enough to make 1000 RPM work by
bumping the duty cycle up until the fans turn even if the fans
don't like it.

Listen closely and run the EC console "faninfo" command to see
the fans start and stop as the system boots and idles.

1. Make pd_choose_voltage set the chosen voltage for use by caller.
2. Add voltage parameter to pd_set_input_current.

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.

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

Add macro for default hibernate delay, and set to 7 days on samus.
Also, adds CONFIG_ option for hibernating early if low on battery.

Added ccprintf("Target shutdown: %.6ld\n", target_time); to print
out target shutdown time after setting it. Verifed the following
on samus
1) If CONFIG_HIBERNATE_DELAY_SEC is left at default 3600 (samus
board.h does not overwrite it), then target time is 3600s.
2) If CONFIG_HIBERNATE_DELAY_SEC is defined in samus/board.h, then
target time equals that value.
3) If CONFIG_HIBERNATE_DELAY_SEC is defined as 1 week and
CONFIG_HIBERNATE_BATT_PCT is defined to 10% and
CONFIG_HIBERNATE_BATT_SEC is 1 day, then when battery is between 8-10%
target time is 1 day and if battery is at 11%, target time is 1 week.

Previous reading of specification left some doubt about how SVDM
responder to 'discover modes' command communicated the number of valid
modes. It is communicated via the 'object position' field in the VDM
header where: opos = modes + 1.
This change adds the mode count to the opos field and sends only that
amount of data back to the initiator. Initiator stores that mode_cnt
so that it can correctly choose a mode when 'enter mode' phase occurs.
