Re: [Renesas Linux Kernel Test Report] DU/Device Tree: Missing pin control for DSI-eDP IRQ

Hi Greg
Cc Geert, Laurent

Linux LTS v6.6 / v6.12 backported this commit

	9133bc3f0564890218cbba6cc7e81ebc0841a6f1
	("drm/bridge: ti-sn65dsi86: Add support for DisplayPort mode with HPD")

Because of that, Renesas needs this commit.

	8219a455efd4ba11c1d30c1bbc9ce853466c19bf
	("arm64: dts: renesas: white-hawk-cpu-common:
	 Add pin control for DSI-eDP IRQ")

Could you please backport it too ?

Thank you for your help !!

Best regards

It does not apply properly to 6.6.y or 6.1.y, so can you provide working
backports there?

I've added it to 6.12.y now.

thanks,

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?

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