Subject: [PATCH 2/4] ARM: dts: at91: sama5d2: mark secumod as a GPIO controller
Date: Tue, 12 Nov 2019 07:19:51 +0000	[thread overview]
Message-ID: <1573543139-8533-2-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1573543139-8533-1-git-send-email-eugen.hristev@microchip.com>

From: Andrei Stefanescu <andrei.stefanescu@microchip.com>

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.
