2010-05-21serial: bfin_sport_uart: add support for CTS/RTS via GPIOsSonic Zhang1-0/+11
Some people need flow control on their ports, so now boards can support that via any GPIOs. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-05-21serial: bfin_sport_uart: work around anomaly 05000473 (make 32bit fifo read atomic)Sonic Zhang1-1/+15
We cannot let a 32-bit RX FIFO read be interrupted otherwise a fake RX underflow error might be generated.

2010-03-02serial: fit blackfin uart over sport driver into common uart infrastructuresonic zhang1-20/+18
Fit blackfin uart over sport driver into common uart inftrastructure. It is based on the early platform interfaces to get the platform data early when the console is initilized. 1. Enable sport uart driver to change uart baud, data bit, stop bit at runtime. Bind the index of uart device nodes to physical index of sports. 2. Move all platform data into arch specific board files. Register and probe platform device data in both early and normal stages. 3. Console is registered in sport uart driver as well. 4. Remove 500 us block waiting in sport tx stop code by putting a dummy data into tx fifo to make sure the sport tx stops when all bytes are shifted out except for the dummy data. 5. clean up a bit and fix up coding style.
