6bdc699401 i2c: add wedge command
This command wedges the I2C bus by writing part of a byte to or reading part
of the response from the slave device.

To enabled the wedge command you must define CONFIG_CMD_I2CWEDGE and you must
define I2C_PORT_HOST, the i2c port to use the wedge command.

BUG=chrome-os-partner:19286
TEST=Manual test on peach pit, spring, and glimmer. Define config in board.h
to enable the command:

On the EC console, execute the following "i2cwedge" command

   i2cwedge 0x90 0 1    (wedge write)
or
   i2cwedge 0x90 0 2    (wedge read)

and then "battery". Observe that the command reports an error.

Similarly, execute

   i2cwedge 0x90 0 5    (wedge write + reboot)
or
   i2cwedge 0x90 0 6    (wedge read + reboot)

on the EC console and observe a reboot. Then execute "battery" and observe
that the command works properly.

bfb16961c7 Samus: Enable manual control of TOUCHSCREEN_RESET_L
The charger task was holding this either on or off in S3, no matter what we
wanted. We really only need to set it at S3->S0 or S3->S5, or when the
lid opens or closes. The rest of the time we should be able to turn it off
and on with gpioset, for testing purposes.

BUG=chrome-os-partner:26502
BRANCH=ToT
TEST=manual

Check the state with

  gpioget TOUCHSCREEN_RESET_L

Open and close the lid, suspend the AP with powerd_dbus_suspend, etc. The
touchscreen should be on when the lid is open and the AP is in either S3 or
S0, off when the lid is closed or the AP is off.

Then

  gpioset TOUCHSCREEN_RESET_L 1
  gpioget TOUCHSCREEN_RESET_L
  gpioset TOUCHSCREEN_RESET_L 0
  gpioget TOUCHSCREEN_RESET_L

The change should persist as long as nothing else changes.

8a9817a5c7 cleanup: Combined i2c unwedge code into one common function
Refactored the i2c unwedge code to place it in the common directory
so that any EC chip can use it.

Added to the STM32F and LM4 boards, code to automatically detect and
unwedge the i2c bus at the start of an i2c transaction. Note that STM32L
already had this ability.

To enable unwedging of the i2c port though, the gpio pins for SDA and
SCL must be defined in the i2c_ports[] array in the board.c file. This
allows the i2c module to bit bang the unwedging for the given port. If
SDA and SCL are not defined for the port, then the unwedge code will
not run.

BUG=chrome-os-partner:26315, chrome-os-partner:23802
BRANCH=none
TEST=Manual testing on machines with different EC chips.

Testing made extensive use of https://chromium-review.googlesource.com/66389
in order to force wedging of the i2c bus so that we can attempt to unwedge
it. Note that you can easily test if the bus is wedged by running i2cscan.

On pit and spring:
On pit, after each of the following, I verified that the bus was automatically
unwedged.
On spring, the unwedge only runs at reboot, so, for the non-reboot wedge
commands, I manually ran console command unwedge, and verified that the bus
became unwedged.
(1) Bit bang a transaction but only read part of the response.
    Command to wedge: i2cwedge 0x90 0 2 2
(2) Bit bang a transaction to do a "write" and stop while the other side is
    acking. Command to wedge: i2cwedge 0x90 0 1
(3) Same as (1) but do a reboot instead of returning and see
    that the unwedge works at init time w/ no cancelled transactions.
    Command to wedge: i2cwedge 0x90 0 6 2
(4) Same as (2) but do a reboot instead of returning and see
    that the unwedge works at init time w/ no cancelled transactions.
    Command to wedge: i2cwedge 0x90 0 5

On glimmer:
Added code to call i2c_unwedge in accel_init(). Then tested unwedging the
accelerometer with the following. One extra difficulty testing this with
the accelerometer is that sometimes the bit you stop on is high, which
means it won't be wedged at all, the next start transaction will reset
the bus. So, sometimes running i2cwedge won't wedge the bus and sometimes
it will depending on the acceleration data.
(1) Big bang transaction to do a "read" of accelerometer and stop partway:
    i2cwedge 0x1c 0x0f 2 2
    i2cscan to make sure bus is actually wedged
    i2cunwedge
    i2cscan to make sure bus is now unwedged.
(2) Bit bang transaction to do a "read" and stop partway, then reboot:
    i2cwedge 0x1c 0x0f 6 2.
    i2cscan to verify that the bus is working after the reboot.

cros_ec_accel driver. First, I verified that without this patch, the kernel
driver throws an error when loading the module. Second, I verified that
with this patch the module was loaded successfully.

6f2869903d rambi: Add motion sense task to track motion
Added motion sense task to Clapper and Glimmer. This task samples
the accelerometers and calculate a lid angle. Note that as
the machine is rotated towards the hinge angle aligning
with gravity, the lid calculation becomes less trustworthy.

Added a math_util file to hold various mathematical functions
useful for calculating lid angle that may be helpful in other
places.

For each board with accelerometers we need to define some
orientation specific data in board.c. There is a calibration
procedure through the EC console that can be enabled by
defining CONFIG_ACCEL_CALIBRATE. The calibration procedure can
help determine the orientation data required.

For debugging purposes there is a console command to regularly
print to the EC console the accelerometer data and derived lid
angle. The console command can be enabled by defining
CONFIG_CMD_LID_ANGLE.

BUG=none
Original-BUG=chrome-os-partner:24703
BRANCH=rambi
TEST=Ran the calibration procedure on a Glimmer unit, and then
rotated the machine in space. Verified that the lid angle
calculated roughly matched actual lid angle.
