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. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

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. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

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 Signed-off-by: Alan Cox

mxser: Split close ready for a standard tty_port_close method

2009-09-19T20:13:21+00:00

Prepare for the tty_port_close function by splitting out methods Signed-off-by: Alan Cox

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) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

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] Signed-off-by: Chuck Ebbert Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

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 Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

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. Cc: "Peter Botha" Signed-off-by: Jiri Slaby Acked-by: Alan Cox Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mxser: remove tty_port_tty_get from mxser_check_modem_status

2009-04-06T21:36:33+00:00

mxser_check_modem_status is called with tty parameter, so the reference should be increased by callers already -- for ioctl syscall it is held whole time gap since open to close, for interrupt, the reference count is increased in the irq handler. There is no tty_kref_put in that function, so this also fixes a refcounting bug. Signed-off-by: Jiri Slaby Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

tty: Introduce some close helpers for ports

2009-01-02T18:19:40+00:00

Again this is a lot of common code we can unify Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds
