Subject: [RFC PATCH 2/2] Droid3: add initial DTS
Date:   Mon, 13 Dec 2021 00:04:59 +0100
Message-Id: <20211212230459.13579-3-merlijn@wizzup.org>

Not everything works yet, but a lot does work:

* serial
* display
* keyboard
* touchscreen
* slider/power button

What doesn't work yet:

* display backlight
* keyboard backlight
