Commit 8219a455efd4ba11 ("arm64: dts: renesas: white-hawk-cpu-common:
Add pin control for DSI-eDP IRQ") has a runtime dependency on commit
10544ec1b3436037 ("pinctrl: renesas: r8a779g0: Add INTC-EX pins,
groups, and function") in v6.11, so you cannot just backport it.
Do we really need it on v6.6?

Thanks!

I'm sorry, but please ignore abouv v6.6.
It was needed for our own kernel (= LTS + backport).
