Subject: [PATCH] arm64: dts: broadcom: add BCM4908 and Asus GT-AC5300 early

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.
