Subject: [PATCH 0/2] Input: cros-ec-keyb: Don't register keyboard if doesn't exist
Date: Tue, 12 Apr 2022 20:33:32 -0700	[thread overview]
Message-ID: <20220413033334.1514008-1-swboyd@chromium.org> (raw)

We're registering a keyboard input device on detachable chromebooks when
that input device doesn't generate any events. This patch series stops
doing that to save some runtime memory and to help userspace understand
that there really isn't a keyboard present when the keyboard is
detached. The second patch is an RFC because it should be picked up
through arm-soc tree, not input tree.

Stephen Boyd (2):
  Input: cros-ec-keyb: Only register keyboard if rows/columns exist
  arm64: dts: qcom: sc7180-trogdor: Remove cros-ec keyboard from
    detachables
