From mboxrd@z Thu Jan 1 00:00:00 1970 From: Johan Hovold Subject: [PATCH v2 4/8] dt-bindings: gnss: add u-blox binding Date: Wed, 30 May 2018 12:32:38 +0200 Message-ID: <20180530103242.20773-5-johan@kernel.org> References: <20180530103242.20773-1-johan@kernel.org> Return-path: In-Reply-To: <20180530103242.20773-1-johan@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman , Rob Herring , Mark Rutland Cc: Andreas Kemnade , Arnd Bergmann , "H . Nikolaus Schaller" , Pavel Machek , Marcel Holtmann , Sebastian Reichel , Tony Lindgren , linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, Johan Hovold List-Id: devicetree@vger.kernel.org Add binding for u-blox GNSS receivers. Note that the u-blox product names encodes form factor (e.g. "neo"), chipset (e.g. "8") and variant (e.g. "q"), but that only formfactor and chipset is used for the compatible strings (for now).
