From 4f8f2bb7ab032150ba94cf60ea5aaf3e3ac3d2ca Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Wed, 8 May 2019 11:19:56 +0200 Subject: mfd: cros_ec: Instantiate properly CrOS Touchpad MCU device Support Touchpad MCU as a special of CrOS EC devices. The current Touchpad MCU is used on Eve Chromebook and used the same protocol as other CrOS EC devices. When a MCU has touchpad support (aka EC_FEATURE_TOUCHPAD), it is instantiated as a special CrOS EC device with device name 'cros_tp'. So regardless of the probing order between the actual cros_ec and cros_tp, the userspace and other kernel drivers should not confuse them.
