Subject: [PATCH 11/11] arm64: dts: qcom: Add support for Microsoft Lumia 950 XL (Cityman)
Date: Mon,  5 Oct 2020 17:03:11 +0200	[thread overview]
Message-ID: <20201005150313.149754-12-konradybcio@gmail.com> (raw)
In-Reply-To: <20201005150313.149754-1-konradybcio@gmail.com>

Add device tree support for Microsoft Lumia 950 XL smartphone.
It is based on the msm8994 chipset and is able to boot Linux
using a custom EDK2 implementation. EL2 core startup is possible
with spin-table, but for now, we'll stick with PSCI.

The board currently supports:
* Screen console via EFIFB
* SDHCI
* I2C
* UART
* PSCI core bringup
