2006-06-19[ARM] 3592/1: AT91RM9200 Serial driver updateAndrew Victor
Patch from Andrew Victor This patch includes a number of updates to the AT91RM9200 serial driver. Changes include: 1. Conversion to a platform_driver. [Ivan Kokshaysky] 2. Replaced all references to AT91RM9200 with AT91. This driver can now also be used for the AT91SAM9216. 3. Allow TIOCM_LOOP to configure local loopback mode. 4. Cleaned up the 'read_status_mask' usage and interrupt handler code. [Chip Coldwell] 5. Suspend/resume support. [David Brownell] There are a few 'unused variable' warning when compiling this - I removed the new DMA support to keep this first patch simpler.

2006-04-30[SERIAL] Clean up serial locking when obtaining a reference to a portRussell King
The locking for the uart_port is over complicated, and can be simplified if we introduce a flag to indicate that a port is "dead" and will be removed. This also helps the validator because it removes a case of non-nested unlock ordering.

* master.kernel.org:/home/rmk/linux-2.6-serial: [SERIAL] Merge avlab serial board entries in parport_serial [SERIAL] kernel console should send CRLF not LFCR
2006-03-20[SERIAL] kernel console should send CRLF not LFCRRussell King
Glen Turner reported that writing LFCR rather than the more traditional CRLF causes issues with some terminals. Since this aflicts many serial drivers, extract the common code to a library function (uart_console_write) and arrange for each driver to supply a "putchar" function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-03-20[SPARC64]: Add SUN4V Hypervisor Console driver.David S. Miller
Since it can do things like BREAK and HUP, we implement this as a serial uart driver. This still needs interrupt probing code, as I haven't figured out how interrupts will work or be probed for on SUN4V yet. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-21[SERIAL] Make uart_port flags a bitwise typeRussell King
Same reasoning as commit 747c8a55946ed037bf7d62454c3c599c02af2262 but this time we're making uart_port flags a bitwise type - not all of these flags correspond with the old ASYNC_ flags, so there is the possibility for bugs if the wrong ASYNC_* constants are used. Always use UPF_* constants for uart_port->flags. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-01-21[SERIAL] Fix UPF_ flag usage with uart_info->flagsRussell King
The previous change found a bug in the serial SAK handling - because we were looking for UPF_SAK set in uart_info->flags, we would never raise a SAK condition. UPF_SAK is in uart_port->flags. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-01-21[SERIAL] Make uart_info flags a bitwise typeRussell King
The potential for confusing the flags is fairly high. Make uart_info's flags a bitwise type so sparse can check that the right flag definitions are used with the right structure. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-01-21[SERIAL] Make port->ops constantRussell King
No one should write to the port->ops structure, so make it constant. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-01-21[SERIAL] Remove UPF_AUTOPROBE and UPF_BOOT_ONLYMCARussell King
The functionality UPF_BOOT_ONLYMCA provided has been replaced by the 8250_mca module, which only registers MCA ports if MCA is present. UPF_AUTOPROBE has no functional effect - in fact, it's never tested. Only ibmasm set the flag. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-08-31[SERIAL] Clean up and fix tty transmission start/stopingRussell King
The start_tx and stop_tx methods were passed a flag to indicate whether the start/stop was from the tty start/stop callbacks, and some drivers used this flag to decide whether to ask the UART to immediately stop transmission (where the UART supports such a feature.) There are other cases when we wish this to occur - when CTS is lowered, or if we change from soft to hard flow control and CTS is inactive. In these cases, this flag was false, and we would allow the transmitter to drain before stopping. There is really only one case where we want to let the transmitter drain before disabling, and that's when we run out of characters to send. Hence, re-jig the start_tx and stop_tx methods to eliminate this flag, and introduce new functions for the special "disable and allow transmitter to drain" case.

2005-07-16[PATCH] Serial: Move deprecation of register_serial forward to SeptemberRussell King

2005-05-09[PATCH] Serial: Add uart_insert_char()Russell King
Add uart_insert_char(), which handles inserting characters into the flip buffer. This helper function handles the correct semantics for handling overrun in addition to inserting normal characters. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
