[PATCH] arm64: dts: qcom: sc7180-trogdor: Remove cros-ec keyboard from detachables

From: Stephen Boyd
Date: Tue Apr 26 2022 - 18:57:56 EST


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. Let's delete the rows/columns properties of the
device node to indicate that there isn't a matrix keyboard on these
boards.
