[PATCH 20/22] arm64: dts: apple: Add A11 devices

Nick Chan
2024-09-11T09:11:19Z

From: Konrad Dybcio <konradybcio@kernel.org>

Add DTS files for the A11 SoC and the following devices based on it:

- iPhone 8
- iPhone 8 Plus
- iPhone X

On A11, Apple has introduced independent performance and efficiency core
clusters, so indicate it in the device tree as well.

[Nick: SMP and m1n1 support, disabled SMC pinctrl]
