Subject: [PATCH v3 05/10] litex serial: add setbrg callback
Date: Tue, 25 May 2021 10:19:47 +0300	[thread overview]
Message-ID: <20210525071952.18045-6-antonynpavlov@gmail.com> (raw)
In-Reply-To: <20210525071952.18045-1-antonynpavlov@gmail.com>

From: Marek Czerski <m.czerski@ap-tech.pl>

setbrg callback (set baudrate) is needed by the loadx/loady commands.
Because litex serial has fixed baudrate the callback only checks if
the requested baudrate is the same as the CONFIG_BAUDRATE.
