From fef377702efc6c6ecab0c323dd72ede4a32fcb02 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Fri, 16 Sep 2016 23:16:42 +0800 Subject: [PATCH] ARM: dts: sun8i: enable UART1 for iNet D978 Rev2 board UART1 is connected to the bluetooth part of RTL8723BS WiFi/BT combo card on iNet D978 Rev2 board. Enable the UART1 to make it possible to use the modified hciattach by Realtek to drive the BT part of RTL8723BS. On the board no r_uart pins are found now (the onboard RX/TX pins are wired to PF2/PF4, which is muxed with mmc0), so also disabled it.
