c18ef5f421 slippy: Enable internal pullup for recovery pin
The recovery pin input from servo is open drain and needs
an internal pullup enabled so it is not always low.

e5ec5f34fc LM4: Support configurable host UART interface
Slippy uses UART2 instead of UART1 and so the EC needs
to be able to tolerate having the host use a different
interface.  There are of course many ways to accomplish
that but this approach adds two config variables to specify
the host uart and the host uart irq.

The UART port setup is split out to allow them to be
configured separately rather than needing to be adjacent
in a for loop.

The interrupt functions were renamed (to ec and host) in
order to indicate which interface they are responsible for.

c882edb530 Clean up SPI GPIOs
SPI is always enabled on pit, so remove #ifdefs

SPI1_CLK was aliased to AC_STATUS, which is left over from snow and
doesn't exist on pit.  That caused it to be driven high briefly during
EC boot.

Also set SPI pins for 40MHz speed so we can try faster SPI clock.

37fcfb732c Fix and enable SPI for pit
I've simplified the SPI module, since we only ever use SPI1 (and there
were already a number of places which assumed this was true).
Somewhere along the way I fixed a number of problems keeping the code
from compiling and working on STM32L.  The code isn't currently used
anywhere else, but should still work there (that is, I don't think I
broke it working on STM32F if you re-enable it on some STM32F
platform).

b061f460eb Define slippy GPIOs, make power sequencing task do nothing.
This specifies the Slippy GPIOs. Because the power controls are completely

01279936cb Unify lid switch processing
STM32-based platforms now use the same lid debouncing code as
LM4-based platforms, generate lid-open / lid-closed events, and
trigger lid-change hooks.

This is needed for disabling keyboard scanning when the lid is closed,
as well as future changes to mask off wake events when the lid is
closed.

4d0c4b1a53 Increase EC low-battery threshold to 14% to match kernel
There is a 4% difference between the kernel's view of battery level and the
actual battery level, to give userspace a chance to shut down cleanly. The
EC should turn the lightbar red when the battery drops below 10%, so this
change makes that happen when the kernel says it's 10%, instead of the real
10%.

Note: We don't have to cherry-pick this to the Link branch. Although it
affects the EC, we already patch the EC lightbar parameters at boot and
that's done in userspace.

BUG=chromium:225500
BRANCH=none
TEST=manual

Unplug Link, let the battery run down. The lightbar should pulse red when
the battery level reported by the UI drops to 9% (there may be a little
delay due to rounding). Note that it's only red when on battery.

108235225d Refactor gpio_set_level() and gpio_pre_init()
gpio_set_level() now allows setting the pin level if GPIO_LOW or
GPIO_HIGH is specified.  Previously, stm32 platforms did this even
though the definition of gpio_set_level() said it wouldn't work.

Fixed gpio_set_level() not setting level after warm reboot on stm32
because it was checking the GPIO_DEFAULT flag in the wrong place.

Fixed LM4 still mucking with alternate function settings and levels
even if GPIO_DEFAULT was specified.

And checked gpio_list[] and all of the calls to gpio_set_flags() to
make sure everything still behaves the same way it did before (or
better, in the case of actual bugs).
