Subject: [PATCH 17/23] ARM: omap: enable am33xx_uart_soft_reset for AM35xx
Date: Fri, 14 Dec 2018 15:17:24 +0100 [thread overview]
Message-ID: <20181214141730.26181-18-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20181214141730.26181-1-s.hauer@pengutronix.de>
am33xx_uart_soft_reset() can be used on AM35xx aswell, so move it
to a more generic place where it can be added to am35xx compilation.
