Subject: [PATCH 2/2] powerpc: wii.dts: Add GPIO keys
Date:   Sat, 12 Jan 2019 17:21:24 +0100
Message-Id: <20190112162124.3341-3-j.neuschaefer@gmx.net>
In-Reply-To: <20190112162124.3341-1-j.neuschaefer@gmx.net>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The Wii has POWER and EJECT buttons, which are connected through
normalization logic to the GPIO controller (the length of an assertion
of these signals is always the same, regardless of how long the user
pressed the buttons).
