From 254b07b2a24c17282e9b69bd253bdb8c73914ea4 Mon Sep 17 00:00:00 2001 From: Chen Feng Date: Thu, 15 Jun 2017 11:04:04 +0800 Subject: [PATCH] arm64: dts: hi3660: Add uarts nodes Add nodes uart0 to uart4 and uart6 for hi3660 SoC. Enable uart3 and uart6, disable uart5, in hikey960 board dts. On HiKey960: - UART6 is used as default console, and is wired out through low speed expansion connector. - UART3 has RTS/CTS hardware handshake, and is wired out through low speed expansion connector. - UART5 is not used in commercial launched boards. So disable it. - UART4 is connected to Bluetooth, WL1837.
