From: Rafał Miłecki <rafal@milecki.pl> A week ago I sent [PATCH RFC] dt-bindings: pinctrl: support specifying pins https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20211110231436.8866-1-zajec5@gmail.com/ From short discussion in that thread it seems that using DT to store pinctrl pins, groups & functions may be an option. I'd like to ask for reviewing my patchset implementing that. Please note it's about describing hardware elements and not actual programming way. It may be used with pinctrl-single.c one day but it's designed as a generic solution for data. Patches 1-4 are for linux-pinctrl.git. Patch 5 I found worth including as DT big example. It can go through Linus with Florian's Ack or I can send it to Florian later.
DT is not the only one, So, I would like to see some kind of roadmap / vision on how this can be useful in the ACPI case. -- With Best Regards, Andy Shevchenko
