Dirk Behme (6): serial: imx: remove unneeded imx_transmit_buffer() from imx_start_tx() serial: imx: TX DMA: clean up sg initialization serial: imx: unmap sg in case of dmaengine_prep_slave_sg() failure serial: imx: unmap scatter gather list in imx_flush_buffer serial: imx: use dma_is_txing to synchronize dma_tx_callback and imx_dma_tx serial: imx: disable TDMAEN in imx_flush_buffer()
Jiada Wang (7): serial: imx: add CREAD flag support serial: imx: use locking to stop concurrent access of UCR1 Revert "serial: imx: always wake up the processes in the TX callback" serial: imx: call imx_dma_tx() again in dma_tx_callback serial: imx: Enable UCR4_OREN in startup interface serial: imx: Fix issue in software flow control serial: imx: Support sw flow control in DMA mode
