tty: mxser: Use the new locking rules to fix setserial properly

2009-12-11T23:18:07+00:00

Propogate the init/shutdown mutex through the setserial logic. Use the proper
locks for the various bits still using the BKL. Kill the BKL in this driver.

Updated to fix the bug noted by Dan Carpenter

tty: mxser: use the tty_port_open method

2009-12-11T23:18:07+00:00

At first this looks a fairly trivial conversion but we can't quite push
everything into the right format yet. The open side is easy but care is needed
over the setserial methods. Fix up the locking now that we've adopted the
port->mutex locking rule for the initialization.

tty: Char: mxser, use THRE for ASPP_OQUEUE ioctl

2009-09-19T20:13:38+00:00

In moxa specific ASPP_OQUEUE ioctl command, they apparently want
only know whether there is space in transmitter hold register.

So switch UART_LSR_TEMT to UART_LSR_THRE in that specific case
according to the change in 1.14 moxa drivers.

tty: Char: mxser, add support for CP112UL

2009-09-19T20:13:38+00:00

Add support for MOXA:0x1120 pci device. It's a 2-port device and differs
in no way from the others. So this turns out to be a trivial
pci_device_id change.

Increase also the version number.

serial: move delta_msr_wait into the tty_port

2009-09-19T20:13:31+00:00

This is used by various drivers not just serial and can be extracted
as commonality

mxser: Split close ready for a standard tty_port_close method

Prepare for the tty_port_close function by splitting out methods

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Remove low_latency flag setting from nozomi and mxser drivers

2009-06-24T16:55:50+00:00

The kernel oopses if this flag is set.

[and neither driver should set it as they call tty_flip_buffer_push from IRQ
 paths so have always been buggy]

tty: Add carrier processing on close to the tty_port core

2009-06-11T15:50:56+00:00

Some drivers implement this internally, others miss it out. Push the
behaviour into the core code as that way everyone will do it consistently.

Update the dtr rts method to raise or lower depending upon flags. Having a
single method in this style fits most of the implementations more cleanly than
two funtions.

We need this in place before we tackle the USB side

char: mxser, fix ISA board lookup

2009-06-10T01:09:03+00:00

There's a bug in the mxser kernel module that still appears in the
2.6.29.4 kernel.

mxser_get_ISA_conf takes a ioaddress as its first argument, by passing the
not of the ioaddr, you're effectively passing 0 which means it won't be
able to talk to an ISA card.  I have tested this, and removing the !
fixes the problem.
