From 4514a7c81234673a764c59e59a0c34c1921f093b Mon Sep 17 00:00:00 2001 From: Andrei Stefanescu Date: Tue, 12 Nov 2019 07:19:51 +0000 Subject: [PATCH] ARM: dts: at91: sama5d2: mark secumod as a GPIO controller The Security Module exposes the PIOBU pins which an be used as regular GPIOs. The PIOBU pins are special because they do not lose their voltage during suspend-to-mem. This patch marks the secumod as a GPIO controller.
