From 267e4a58245c765c7e621bfa9b6d5589effcfe01 Mon Sep 17 00:00:00 2001 From: Wei-Ning Huang Date: Mon, 24 Apr 2017 18:53:22 +0800 Subject: [PATCH] mb/google/eve: switch touchpad devicetree to i2c-hid and cros_ec i2c device The new touchpad firmware uses i2c-hid instead of custom reporting protocol. The touchpad also exposed another slave address (0x1e) for kernel to communicate with the touchpad EC.
