[PATCH V2 0/6] pinctrl: support platform (e.g. DT) stored pins, groups & functions

[Rafał Miłecki <zajec5@xxxxxxxxx>]

From: Rafał Miłecki <rafal@xxxxxxxxxx>

Two weeks ago I sent
[PATCH RFC] dt-bindings: pinctrl: support specifying pins
https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20211110231436.8866-1-zajec5@xxxxxxxxx/

and week ago I sent
[PATCH 0/5] pinctrl: allow storing pins, groups & functions in DT
https://patchwork.ozlabs.org/project/linux-gpio/list/?series=272685

Initially I planned to allow putting some pinctrl hw details in DT and
later that evolved into a slightly more generic API.

Again:
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 1-5 are for linux-pinctrl.git. Patch 6 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 (6):
  dt-bindings: pinctrl: support specifying pins, groups & functions
  dt-bindings: pinctrl: brcm,ns-pinmux: extend example
  pinctrl: prepare API for reading pins, groups & functions
  pinctrl: support reading pins, groups & functions from DT
  pinctrl: bcm: pinctrl-ns: supoprt DT specified pins, groups &
    functions
  ARM: dts: BCM5301X: add pinctrl pins, groups & functions
