Subject: arm64: dts: allwinner: a523: Add UART1 pins
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=64f2f7bc4acb7928b39cac4a9a932e77b966f31c;p=thirdparty%2Flinux.git

arm64: dts: allwinner: a523: Add UART1 pins

UART1 is normally used to connect to the Bluetooth side of a Broadcom
WiFi+BT combo chip. The connection uses 4 pins.

Add pinmux nodes for UART1, one for the RX/TX pins, and one for the
RTS/CTS pins.
