Subject: [PATCH 3/5] dt-bindings: add more optional properties for elan_i2c touchpads
Date: Fri, 12 Oct 2018 16:24:11 +0200 [thread overview]
Message-ID: <20181012142413.26107-4-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <20181012142413.26107-1-benjamin.tissoires@redhat.com>
Some new touchpads IC are connected through PS/2 and I2C. On some of these
new IC, the I2C part doesn't have all of the information available.
We need to be able to forward the touchpad parameters from PS/2 and
thus, we need those new optional properties.
