Hello, v4 wasn't discussed to an end, but I think I avoided all concerns with this version. Changes since v4: - rebased to v4.13, applies fine on current tty-testing - moved code to serial_core.c - made of_get_rs485_mode return void to stop the return code discussion - grabbed authorship of patch 1 as it hardly resembled the original.
