[PATCH v2] arm64: dts: amlogic: enable some device nodes for S4

From: Xianwei Zhao via B4 Relay
Date: Tue Jul 09 2024 - 05:32:14 EST

From: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>

Enable more device nodes for AQ222 base S4, including
SD, regulator and ethnernet node.

Reviewed-by: Neil Armstrong <neil.armstrong@xxxxxxxxxx>
Signed-off-by: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>
---
Add more device nodes for S4.
---
Changes in v2:
- Delete status of regulator-vddcpu node, use default status OK.
- Link to v1: https://lore.kernel.org/r/20240705-s4_node-v1-1-646ca7ac4f09@xxxxxxxxxxx
