[PATCH 2/5] ARM: ux500: Allow the ccu8540 to register its serial devices without pdata

From: Lee Jones
Date: Fri Mar 22 2013 - 11:28:40 EST


The u8540 doesn't have DMA support yet, so in order to enable
serial and receive post-bootconsole output, we cannot supply the same
platform data as we would for the u8500.
