[PATCH] serial/lpuart: Do not enable UART FIFO

2018-04-12 Thread Andrey Smirnov
Using FIFO in LPUART results in subtle serial input draining issues which are quite difficult to reproduce and troubleshoot. Since the change offered only moderate performance gain revert the code to operate in no-FIFO mode to avoid FIFO-related problems alltogether. Signed-off-by: Andrey Smirnov
