From dc320815305c5f019672d144f4c4c2710ef7732e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 2 Jul 2008 10:58:45 +0200 Subject: cpm_uart: Support uart_wait_until_sent() Set port->fifosize to the software FIFO size, and update the port timeout when the baud rate is modified. SCC ports have an optional 32 byte hardware FIFO which is currently not taken into account, as there is no documented way to check when the FIFO becomes empty.
