From 9b11f19e414b1d1314ee581e8c1e084bced8e5cc Mon Sep 17 00:00:00 2001 From: Thomas Rohloff Date: Sun, 5 Nov 2017 20:36:30 +0100 Subject: [PATCH] tty: serial: meson: allow baud-rates lower than 9600 Devices like DCF77 receivers need the baud-rate to be as low as 50. I have tested this on a Meson GXL device with uart_A.
