From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anson Huang Subject: [PATCH 1/2] clk: imx: imx7d: add the snvs clock Date: Thu, 4 Jan 2018 23:06:41 +0800 Message-ID: <1515078402-22135-1-git-send-email-Anson.Huang@nxp.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org, linux-clk@vger.kernel.org, linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, linux-imx@nxp.com Cc: shawnguo@kernel.org, kernel@pengutronix.de, fabio.estevam@nxp.com, mturquette@baylibre.com, sboyd@codeaurora.org, robh+dt@kernel.org, mark.rutland@arm.com, stefan@agner.ch, linux@armlinux.org.uk List-Id: devicetree@vger.kernel.org According to the i.MX7D Reference Manual, SNVS block has a clock gate, accessing SNVS block would need this clock gate to be enabled, add it into clock tree so that SNVS module driver can operate this clock gate.
