Subject: [PATCH v2] arm64: dts: qcom: sc7180-trogdor: Split out keyboard node and describe detachables
Trogdor devices that have a detachable keyboard still have a
non-detachable keyboard input device present because we include the
cros-ec-keyboard.dtsi snippet in the top-level sc7180-trogdor.dtsi file
that every variant board includes. We do this because the
keyboard-controller node also provides some buttons like the power
button and volume buttons. Unfortunately, this means we register a
keyboard input device that doesn't do anything on boards with a
detachable keyboard.
Change the node's compatible on detachables to the newly introduced
"google,cros-ec-keyb-switches" compatible to indicate that there are
only switches and no keyboard to register. Similarly, move the keyboard
include that defines the keyboard-controller node out of
sc7180-trogdor.dtsi to boards that actually have a keyboard so that the
matrix properties are not defined on boards with the switches
compatible. Future boards can either use the include approach or the
node definition approach to describe a keyboard with possible switches
or just some switches.
