* [SERIAL] Remove unused variable in sa1100.cRussell King2005-11-191-1/+0
| | | | | | | Since the spinlock was removed from sa1100_start_tx(), the "flags" variable becomes redundant. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [SERIAL] sa1100_start_tx spinlock recursionFlorin Malita2005-11-121-3/+1
| | | | | | | | | | | | | | | | | | The serial core aquires the port spinlock before calling port->ops->start_tx(), so sa1100_start_tx() shouldn't try to lock it again.

* [DRIVER MODEL] Convert platform drivers to use struct platform_driverRussell King2005-11-091-16/+16
| | | | | | | | | This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
* Create platform_device.h to contain all the platform device details.Russell King2005-10-291-1/+1

* [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King2005-10-281-4/+4
| | | | | | | | | | | | | | | | In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

* [ARM] 2907/1: GCC 4 serial driver compile fixesVincent Sanders2005-09-141-1/+1
| | | | | | | | | | Patch from Vincent Sanders When building the ARM platforms several serial drivers fail to compile with GCC 4.01 due to extern/static ambiguity. Signed-off-by: Vincent Sanders <vince@arm.linux.org.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [SERIAL] Clean up and fix tty transmission start/stopingRussell King2005-08-311-4/+4
| | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] Serial: Add uart_insert_char()Russell King2005-05-091-4/+1
| | | | | | | | 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>

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!
