[PATCH 0/5] pinctrl: allow storing pins, groups & functions in DT

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.

Rafał Miłecki (5):
  dt-bindings: pinctrl: support specifying pins, groups & functions
  dt-bindings: pinctrl: brcm,ns-pinmux: extend example
  pinctrl: add helpers reading pins, groups & functions from DT
  pinctrl: bcm: pinctrl-ns: supoprt DT specified pins, groups &
    functions
  ARM: dts: BCM5301X: add pinctrl pins, groups & functions
