From ae0fc941527cc74e7aeef700e5dbe07848a00bfb Mon Sep 17 00:00:00 2001 From: Jorik Jonker Date: Mon, 12 Sep 2016 20:12:44 +0200 Subject: [PATCH] dts: sun8i-h3: split off RTS/CTS for UART1 in seperate pinmux This was done to make UART1-3 on H3 consistent, and less complicated to enable UART1-3 on the breakout header on the several H3 board (notably Orange Pi's). This patch adds a bit of complexity for the existing Banana Pi, which already had the RTS/CTS associated on UART1. The RTS/CTS for UART2-3 could be defined in the same way, but since there is no actual use case for them at the moment, they are left out.
