+Subject: [PATCH] Add flush_buffer() operation to uart_ops
+
+Serial drivers using DMA (like the Atmel USART3 driver) tend to get
+very confused when the xmit buffer is flushed and nobody told them.
+They also tend to spew a lot of garbage since the DMA engine keeps
+running after the buffer is flushed and possibly refilled with
+unrelated data.
+
+This patch adds a new flush_buffer operation to the uart_ops struct,
+along with a call to it from uart_flush_buffer() right after the xmit
+buffer has been cleared. The driver can implement this in order to
+syncronize its internal DMA state with the xmit buffer when the buffer
+is flushed.
