From ec84aa0a920192df56624961cb146947d7d9e11e Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 11 Dec 2016 21:42:23 +0100 Subject: tty: serial: lantiq: implement earlycon support This allows enabling earlycon for devices with a Lantiq serial console by splitting lqasc_serial_port_write() from lqasc_console_write() and re-using the new function for earlycon's write callback. The kernel-parameter name matches the driver name ("lantiq"), similar to how other drivers implement this.
