revert "x86, serial: convert legacy COM ports to platform devices"

2007-08-22T23:23:25Z

Revert 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26. It broke Sébastien Dugué's machine and Jeff said (persuasively) This seems like it will break decades-long-working stuff, in favor of breaking new ground in our favorite area, "trusting the BIOS." It's just not worth it for serial ports, IMO. Serial ports are something that just shouldn't break at this late stage in the game. My new Intel platform boxes don't even have serial ports, so I question the value of messing with serial port probing even more... because... just wait a year, and your box won't have a serial port either! :) I certainly don't object to the use of platform devices (or isa_driver), but the probe change seems questionable. That's sorta analagous to rewriting the floppy driver probe routine. Sure you could do it... but why risk all that damage and go through debugging all over again? It seems clear from this report that we cannot, should not, trust BIOS for something (a) so simple and (b) that has been working for over a decade. Much discussion ensued and we've decided to have another go at all of this.

serial: clear proper MPSC interrupt cause bits

2007-06-28T18:38:29Z

The interrupt clearing code in mpsc_sdma_intr_ack() mistakenly clears the interrupt for both controllers instead of just the one its supposed to. This can result in the other controller appearing to hang because its interrupt was effectively lost. So, don't clear the interrupt cause bits for both MPSC controllers when clearing the interrupt for one of them. Just clear the one that is supposed to be cleared.

Blackfin serial driver: ignore framing and parity errors

2007-06-11T07:31:30Z

if we get a break signal, we want to ignore framing and parity errors because those will always be set (by nature of the signal) Signed-off-by: Mike Frysinger Signed-off-by: Bryan Wu

The -rt patch triggered a lockdep warning in the amba serial drivers, which never shows up on UP kernels. On SMP systems this would trigger as well. Release the port lock before calling tty_flip_buffer_push() and reacquire it after the call. This matches the code in the 8250 serial driver. Signed-off-by: Thomas Gleixner Signed-off-by: Russell King
