From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stefan Popa Subject: [PATCH v4 2/4] dt-bindings: iio: adc: Add common ADCs properties to a separate file Date: Fri, 9 Nov 2018 17:40:55 +0200 Message-ID: <1541778055-7629-1-git-send-email-stefan.popa@analog.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: jic23@kernel.org, robh+dt@kernel.org Cc: mark.rutland@arm.com, knaack.h@gmx.de, lars@metafoo.de, pmeerw@pmeerw.net, Michael.Hennerich@analog.com, gregkh@linuxfoundation.org, linux-iio@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, stefan.popa@analog.com List-Id: devicetree@vger.kernel.org There are several ADC drivers that depend on the same device tree bindings. Rather than continue to duplicate the properties, this patch adds a common adc binding document that can be referenced. For beginning, only two properties are documented.
