2010-03-02serial: fit blackfin uart over sport driver into common uart infrastructuresonic zhang
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.

2009-11-25serial: sh-sci: Depend on HAVE_CLK unconditionally.Paul Mundt
The sh-sci code conditionalized the clock framework support in order to give the other platforms a chance to catch up. sh64 supported this some time ago and the forthcoming ARM changes handle this as well, this leaves h8300 as the odd one out. H8300 has had since 2.5 to merge it's sh-sci support upstream, and has yet to do so. At this point I will no longer be holding back the driver to support an unreponsive architecture, 7 years is quite enough of a grace period. Support is easily implemented on the architecture if and when it ever decides to merge its changes upstream. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Add support for the nwp serial device which is connected to a DCR bus. It uses the of_serial device driver to determine necessary properties from the device tree. The supported device is added as serial port number 85. NWP stands for network processor and it is part of the QPACE - Quantum Chromodynamics Parallel Computing on the Cell Broadband Engine project. The implementation is a lightweight uart implementation with the focus to consume as little resources as possible and it is connected to a DCR bus.

2008-10-13serial: allow 8250 to be used on sparcDavid Miller
This requires three changes: 1) Remove !SPARC restriction in Kconfig. 2) Move Sparc specific serial drivers before 8250, so that serial console devices don't change names on us, even if 8250 finds devices. 3) Since the Sparc specific serial drivers try to use the same major/minor device namespace as 8250, some coordination is necessary. Use the sunserial_*() layer routines to allocate minor number space within TTY_MAJOR when CONFIG_SPARC. This has no effect on other platforms.

Trying to compile the v850 port brings many compile errors, one of them exists since at least kernel 2.6.19. There also seems to be noone willing to bring this port back into a usable state. This patch therefore removes the v850 port. If anyone ever decides to revive the v850 port the code will still be available from older kernels, and it wouldn't be impossible for the port to reenter the kernel if it would become actively maintained again.
