From 013df97be45f023f5902c1102606c4034c668ba5 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 9 Apr 2019 00:57:43 +0800 Subject: [PATCH] ARM: dts: sun8i: a83t: Add I2C2 pinmux setting for PE pins 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.
