From b753e41d9999c040c601de53cc1e072160472d80 Mon Sep 17 00:00:00 2001 From: Drew Fustini Date: Tue, 22 Sep 2020 00:50:55 +0200 Subject: ARM: dts: am33xx: modify AM33XX_IOPAD for #pinctrl-cells = 2 Modify the AM33XX_IOPAD macro so that it works now that #pinctrl-cells = <2>. The third parameter is just a zero and the pinctrl-single driver will just OR this with the second parameter so it has no actual effect. There are no longer any dts files using this macro (following my patch to am335x-guardian.dts), but this will keep dts files not in mainline from breaking.
