## Summary * xtensa/esp32s2: add UART RS485 support ## Impact Only ESP32S2 ## Testing ESP32S2-Saola board with `esp32s2-saola-1:nsh` config with `UART 1` option enabled under the `System Type -> ESP32-S2 Peripheral Selection` and `RS-485 on UART1` option enabled under the `System Type -> UART Configuration`. - Transmitter side tested with `echo "test" >> /dev/ttyS1` command(s) using nsh and serialblaster example under `Application Configuration -> Examples -> Serial Blaster example` using `serialblaster /dev/ttyS1` command with using a logic analyzer. [idf uart echo rs485](https://github.com/espressif/esp-idf/tree/master/examples/peripherals/uart/uart_echo_rs485) example on another chip can be used as well. - Recieve side tested with serialrx example under `Application Configuration -> Examples -> Serial RX example` with using [idf hello_world example](https://github.com/espressif/esp-idf/tree/master/examples/get-started/hello_world) on another chip and connected to the esp32s2 (Other chip's TX - GPIO18, Other chip's RX to - GPIO17). `serialrx /dev/ttyS1 15` command used to get byte count. To check the data please change `Output method` option to `String` under the `Application Configuration -> Examples -> Serial RX example`. -- This is an automated message from the Apache Git Service.
