Subject: [PATCH v3 5/5] ARM: dts: rskrza1: Add input switches
Date:   Thu,  2 May 2019 14:32:20 +0200
Message-Id: <20190502123220.3016-6-geert+renesas@glider.be>
In-Reply-To: <20190502123220.3016-1-geert+renesas@glider.be>
References: <20190502123220.3016-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v3:
  - No changes,

v2:
  - No changes,

v1:
  - Use rza1-irqc instead of gic.

v0:
  - Sent as an RFC in a reply to another thread.
