[PATCH 1/2] arm64: tegra: Use consistent key code for force-recovery button
From: Thierry Reding
Date: Thu Aug 27 2026 - 10:56:43 EST
From: Thierry Reding <treding@xxxxxxxxxx>
Some boards use the KEY_SLEEP input key code for the force-recovery
button, whereas others use BTN_1. The latter isn't valid because it only
applies to devices marked CAP_POINTER. Use KEY_SLEEP consistently for
all devices.
On certain Tegra234 devices there are definitions for a suspend key that
uses KEY_SLEEP, but I couldn't find any references to this key in any of
the board documents, so remove them.
