Subject: [PATCH] ARM: OMAP2+: Fix serial init for device tree based booting
Date: Fri, 7 Jun 2013 14:55:04 -0700 [thread overview]
Message-ID: <20130607215503.GK3331@atomide.com> (raw)
We don't want to call omap_serial_early_init() for device
tree based booting as the ports are initialized based on
the .dts entries.
