Subject: [PATCH v2 08/19] ARM64: dts: Add Renesas R8A77965 SoC support
Date:   Tue, 20 Feb 2018 16:12:10 +0100
Message-Id: <1519139541-18783-9-git-send-email-jacopo+renesas@jmondi.org>
In-Reply-To: <1519139541-18783-1-git-send-email-jacopo+renesas@jmondi.org>
References: <1519139541-18783-1-git-send-email-jacopo+renesas@jmondi.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Basic support for the Gen 3 R-Car M3-N SoC.

Based on original work from:
Takeshi Kihara <takeshi.kihara.df@renesas.com>
Magnus Damm <damm+renesas@opensource.se>

Signed-off-by: Jacopo Mondi <jacopo+renesas@jmondi.org>

---
v1 -> v2:
- Split r8a77965.dtsi from patch v1 [5/15]
- Replace all PD_ and CLK_ defines with numeric entries
- Move timer and pmu nodes outside of soc node and replace their
  "interrupt" property with "interrupt-extended" one
- Fix license header
