From b7f865ede20c87073216f77fe97f6fc56666e3da Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Tue, 25 Oct 2016 01:08:31 +0800 Subject: ARM: dts: sun8i: fix the pinmux for UART1 When the patch is applied, the allwinner,driver and allwinner,pull properties are removed. Although they're described to be optional in the devicetree binding, without them, the pinmux cannot be initialized, and the uart cannot be used. Add them back to fix the problem, and makes the bluetooth on iNet D978 Rev2 board work.
