From 38b349cb35738377cf42b71afa9e5d66e1a8eb4b Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Sun, 19 Apr 2020 17:40:22 -0700 Subject: ec/google/chromeec: Add driver for i2c_tunnel device under Chrome EC This change enables support for generating ACPI nodes for I2C tunnel for any GOOG0012 device that is sitting behind the Chrome EC. It accepts a config "remote_bus" which allows mainboard to configure the id of the remote bus that is being tunneled. BUG=b:154290952 BRANCH=None TEST=Verified that SSDT node for I2C tunnel behind Chrome EC is generated correctly.
