Other MT65xx devicetrees have GIC as parent for itself and SYSIRQ, so I assume.

not really, downstream has no mentions about SYSIRQ or its' address

[PATCH 11/11] ARM: dts: mediatek: add basic support for Lenovo A369i board

[Max Shevchenko via B4 Relay]

From: Max Shevchenko <wctrl@proton.me>

This smartphone uses a MediaTek MT6572 system-on-chip with 512MB of RAM.
It can currently boot into initramfs with a working UART and
Simple Framebuffer using already initialized panel by the bootloader.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: using specified base-commit 0ff41df1cb268fc69e703a08a57ee14ae967d0ca

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
