From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chunfeng Yun Subject: [PATCH v2 6/6] dt-bindings: mt8173-mtu3: add reference clock Date: Mon, 6 Feb 2017 17:29:01 +0800 Message-ID: <1486373341-4399-6-git-send-email-chunfeng.yun@mediatek.com> References: <1486373341-4399-1-git-send-email-chunfeng.yun@mediatek.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1486373341-4399-1-git-send-email-chunfeng.yun@mediatek.com> Sender: linux-kernel-owner@vger.kernel.org To: Mathias Nyman , Felipe Balbi Cc: Greg Kroah-Hartman , Matthias Brugger , Rob Herring , Mark Rutland , Ian Campbell , Chunfeng Yun , linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-usb@vger.kernel.org, linux-mediatek@lists.infradead.org, devicetree@vger.kernel.org List-Id: devicetree@vger.kernel.org Due to the reference clock comes from 26M oscillator directly on mt8173, and it is a fixed-clock in DTS which always turned on, we ignore it before. But on some platforms, it comes from PLL, and need be controlled, so here add it, no matter it is a fixed-clock or not.
