From mboxrd@z Thu Jan 1 00:00:00 1970 From: gregory.clement@free-electrons.com (Gregory CLEMENT) Date: Thu, 15 Jan 2015 11:47:02 +0100 Subject: [PATCH v3 1/5] rtc: armada38x: Add the device tree binding documentation In-Reply-To: <1421318826-27268-1-git-send-email-gregory.clement@free-electrons.com> References: <1421318826-27268-1-git-send-email-gregory.clement@free-electrons.com> Message-ID: <1421318826-27268-2-git-send-email-gregory.clement@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The Armada 38x SoCs come with a new RTC which differs from the one used in the other mvebu SoCs until now. This patch describes the binding of this RTC.
