Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

tty: serial: define UART_LCR_WLEN() macro Define a generic UART_LCR_WLEN() macro with a size argument. It can be used to encode byte size into an LCR value. Therefore we can use it to simplify the drivers using tty_get_char_size() in the next patches.

tty: move the async flags from the serial code into the tty includes These are used with the tty_port flags which are tty generic so move the flags into a more sensible place. This then makes it possible to add helpers such as those suggested by Huang Shijie. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[PATCH] Serial: Move deprecation of register_serial forward to September I think it's about time to make the build a little more vocal about the expiry of these functions. Due to recent discussions with problems in the console initialisation vs power manglement, I'd like to move the date forward to September. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
