From da801ab56ad874897b0b255216767c983e665a4c Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Thu, 20 Dec 2018 15:44:31 +0100 Subject: pinctrl: ocelot: add MSCC Jaguar2 support Jaguar2 has the same register layout as Ocelot but it has 64 pins, meaning that there are 2 registers instead of one.
