Subject: [PATCH 1/5] ARM: dts: sun8i: r40: Add pinmux settings for UART3 on PG pingroup
Date: Wed, 9 Jan 2019 23:02:53 +0800 [thread overview]
Message-ID: <20190109150257.12602-2-wens@csie.org> (raw)
In-Reply-To: <20190109150257.12602-1-wens@csie.org>
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.
