Subject: cros_ec: Use udevice instead of cros_ec_dev for keyboard functions
X-Git-Tag: v2016.01-rc2~235
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=745009c4d081a9fb5504ce3e97b39e92cbe77ef4;p=platform%2Fkernel%2Fu-boot.git

cros_ec: Use udevice instead of cros_ec_dev for keyboard functions

In preparation for converting the cros_ec keyboard driver to driver model,
adjust the cros_ec functions it will use to use a normal struct udevice.
