[PATCH v2 20/22] arm64: dts: apple: Add A11 devices

From: Nick Chan
Date: Sat Sep 14 2024 - 01:32:13 EST

From: Konrad Dybcio <konradybcio@xxxxxxxxxx>

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]
