Subject: [PATCH v1 3/3] arm64: dts: exynos: add initial support for Samsung Galaxy S7
Samsung Galaxy S7 (SM-G930F), codenamed herolte, is a mobile phone from
2016. It features 4GB RAM, 32/64GB UFS 2.0, Exynos 8890 SoC and a
1440x2960 Super AMOLED display.
Implement initial support for this device, including:
- simple-framebuffer
- gpio-keys
- s2mps16 and max77838
- mmc
- usb, configured to be in peripheral mode
