Subject: serial: pl01x: set baudrate when probing
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=91febe80c9f2434170c6c2e866942c75372aed75;p=u-boot.git

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.
