From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chen-Yu Tsai Subject: [PATCH 5/6] ARM: dts: sun8i: a83t: Add I2C2 pinmux setting for PE pins Date: Tue, 9 Apr 2019 00:57:43 +0800 Message-ID: <20190408165744.11672-6-wens@kernel.org> References: <20190408165744.11672-1-wens@kernel.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20190408165744.11672-1-wens@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Maxime Ripard , Michael Turquette , Stephen Boyd , Rob Herring , Mark Rutland , Yong Deng , Mauro Carvalho Chehab Cc: Chen-Yu Tsai , linux-arm-kernel@lists.infradead.org, linux-clk@vger.kernel.org, linux-media@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, Paul Kocialkowski List-Id: devicetree@vger.kernel.org From: Chen-Yu Tsai I2C2 is available on the PE pingroup, on the same pins as the camera sensor interface (CSI) controller's camera control interface pins. This provides an option to use I2C2 instead of that control interface to configure camera sensors. Add a pinctrl node for it. The property /omit-if-no-ref/ is added to keep the device tree blob size down if it is unused.
