From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thierry Escande Subject: [PATCH v2] arm64: dts: apq8096-db820c: Removed bt-en-1-8v regulator Date: Thu, 24 May 2018 20:01:55 +0200 Message-ID: <20180524180155.24839-1-thierry.escande@linaro.org> Mime-Version: 1.0 Content-Type: text/plain; charset = "utf-8" Return-path: Content-Transfert-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org To: Andy Gross , David Brown , Rob Herring , Mark Rutland , Catalin Marinas , Will Deacon Cc: Bjorn Andersson , Niklas Cassel , linux-arm-msm@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org This patch removes the unused bt-en-1-8v regulator and moves the bt_en_gios claim to the pm8994_gpios node. This bt_en_gpio could have been moved to the bluetooth serial node but instead this node declares an 'enable' gpio addressing the bt_en_gpio. This is needed by the Qualcomm QCA6174 WLAN/BT combo chip that needs to have the bt_en_gpio claimed even if only WLAN is used.
