From: Alexander Stein Date: Thu, 9 Jul 2015 08:34:34 +0000 (+0200) Subject: serial/uuc_uart: Support higher bitrates than 115200 Bit/s X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e5eb517dd80e4da3055895f8aa3547c2bfd5e675;p=deliverable%2Flinux.git serial/uuc_uart: Support higher bitrates than 115200 Bit/s The maximum bitrate supported depends on the clock rate used in BRG. This is stored in port.uartclk during probe. Respecting the 16x oversampling higher bitrates can be supported.
