From 35b81a037b2ee78f05d17e0856f0005ad8fc67f1 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven <geert+renesas@glider.be> Date: Thu, 2 May 2019 14:32:20 +0200 Subject: ARM: dts: rskrza1: Add input switches Add support for input switches SW1-3 on the Renesas RZ/A1 RSK+RZA1 development board. Note that this uses the IRQ interrupts, as the RZ/A1 GPIO controller does not include interrupt support.
