Subject: [PATCH 7/8] ARM: dts: omap4-droid4: Add touchscreen
Date: Thu, 2 Mar 2017 02:08:59 +0100 [thread overview]
Message-ID: <20170302010900.28532-8-sre@kernel.org> (raw)
In-Reply-To: <20170302010900.28532-1-sre@kernel.org>
Droid4's touchscreen can be used with mainline's maxtouch
driver. The touchscreen's lower area is used for four soft
buttons (KEY_MENU, KEY_HOME, KEY_BACK, KEY_SEARCH), but that
is currently not supported by the mainline kernel.
