From 26e9ffeb2c04f0f577d0179e7eca8e1d54f9e050 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 9 Jan 2019 23:02:53 +0800 Subject: [PATCH] ARM: dts: sun8i: r40: Add pinmux settings for UART3 on PG pingroup UART3 on the PG pingroup on the R40 SoC is commonly used to connect the bluetooth controller in a WiFi+Bluetooth combo chip, with the WiFi bits also on the PG pingroup. This patch adds two device nodes for UART3 on PG pingroup, one for the RX/TX pins, and one for the RTS/CTS pins. Consumers can reference either just the RX/TX pinmux setting or both, depending on the application.
