From f26b260c69f1d92940f82b3d6674a7b70a967dfc Mon Sep 17 00:00:00 2001 From: Georgii Staroselskii Date: Tue, 11 Sep 2018 13:31:08 +0300 Subject: [PATCH] x86: dts: edison: configure I2C#6 pins Now that we have the pinctrl driver for Merrifield in place we can make use of it and set I2C#6 pins appropriately. Initial configuration came from the firmware. Which quite likely has been used in the phones, where that is not part of Atom peripheral, is in use. Thus we need to override the leftover.
