[PATCH v1 7/7] arm64: boot: dts: Add initial support for Samsung Galaxy Note20 5G (c1s)
Posted by Igor Belwon 1 month, 1 week ago 
Add initial support for the Samsung Galaxy Note20 5G (c1s/SM-N981B)
phone. It was launched in 2020, and it's based on the Exynos 990 SoC. It
has only one configuration with 8GB of RAM, albeit storage options may
differ.

This device tree adds support for the following:

- SimpleFB
- 8GB RAM
- Buttons

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:
