From 2961f69f151c0a6771f55cef46398fe49ca20902 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 12 Nov 2020 16:08:32 +0100 Subject: [PATCH] arm64: dts: broadcom: add BCM4908 and Asus GT-AC5300 early DTS files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit They don't descibe hardware fully yet but it's enough to boot a system. Some missing blocks: 1. PMC (Power Management Controller?) 2. Ethernet 3. Crypto 4. Thermal Asus DTS is missing defining full NAND partitions layout and buttons. Further changes will fill those gaps as soon as required bindings will be found / tested / added.
