From 91febe80c9f2434170c6c2e866942c75372aed75 Mon Sep 17 00:00:00 2001 From: Yang Xiwen Date: Wed, 28 Feb 2024 18:57:52 +0800 Subject: [PATCH] serial: pl01x: set baudrate when probing It is found that when DM is enabled, only generic init function is called in .probe(). Baudrate is never honored. Add a function call to .setbrg() when probing so that we can update the baudrate of the serial device.
