Merge tag 'chrome-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/chrome-platform
Pull chrome platform updates from Olof Johansson:
"Here's a set of updates to the Chrome OS platform drivers for this
merge window.
Main new things this cycle is:
- Driver changes to expose the lightbar to users. With this, you can
make your own blinkenlights on Chromebook Pixels.
- Changes in the way that the atmel_mxt trackpads are probed. The
laptop driver is trying to be smart and not instantiate the devices
that don't answer to probe. For the trackpad that can come up in
two modes (bootloader or regular), this gets complicated since the
driver already knows how to handle the two modes including the
actual addresses used. So now the laptop driver needs to know more
too, instantiating the regular address even if the bootloader one
is the probe that passed.
- mfd driver improvements by Javier Martines Canillas, and a few
bugfixes from him, kbuild and myself"
