[PATCH v3 2/2] pinctrl: ocelot: Extend support for lan966x

From: Kavyasree Kotagiri
Date: Mon Nov 01 2021 - 05:56:25 EST

Next message: Borislav Petkov: "[GIT PULL] x86/cc for v5.16"
Previous message: Kavyasree Kotagiri: "[PATCH v3 1/2] dt-bindings: pinctrl: ocelot: add lan966x SoC support"
In reply to: Rob Herring: "Re: [PATCH v3 1/2] dt-bindings: pinctrl: ocelot: add lan966x SoC support"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This patch extends pinctrl-ocelot driver to support also the
lan966x. Register layout is same as ocelot. It has 78 GPIOs.
Requires 3 registers ALT0, ALT1, ALT2 to configure ALT mode.

Signed-off-by: Kavyasree Kotagiri <kavyasree.kotagiri@xxxxxxxxxxxxx>
---
v2 -> v3:
- Removed extra new lines in pinctrl-ocelot.
- Reverted sparx5_desc changes which are done by mistake.

v1 -> v2:
- Use consistent name lan966x everywhere.
