Unfortunately, this driver does not yet appear to have fully functional DMA on OMAP3630/DM3730 which causes some timeouts and frame errors. This patch removes the DMA entry from the device tree which allow the UART to operate without Bluetooth frame errors. If/when DMA is working on OMAP3630, this should be reverted.
