7760a47892 google/veyron*: Pulse the i2c clock once if sda was low
On one particular TV the TV was holding SDA low when it came up.  It
would release the SDA when the SCL went low the first time.
Unfortunately the HDMI i2c port wouldn't transmit until the SDA was
released.

Let's detect this case and insert a bogus clock pulse to try to get the
other side to release SDA.

It's unclear why the kernel doesn't have this problem.

a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

113ef81bf4 google/veyron_mickey: Add new mainboard
This simply copies veyron_brain to veyron_mickey and makes the
minimal set of changes (s/brain/mickey) to make it compile. The
follow-up patch will take into account board differences.
