4 Subject: [PATCH] arm64: dts: broadcom: add BCM4908 and Asus GT-AC5300 early
5 DTS files
6 MIME-Version: 1.0
7 Content-Type: text/plain; charset=UTF-8
8 Content-Transfer-Encoding: 8bit

10 They don't descibe hardware fully yet but it's enough to boot a system.
11
12 Some missing blocks:
13 1. PMC (Power Management Controller?)
14 2. Ethernet
15 3. Crypto
16 4. Thermal
17
18 Asus DTS is missing defining full NAND partitions layout and buttons.
19
20 Further changes will fill those gaps as soon as required bindings will
21 be found / tested / added.
