David S. Miller f5deb807b8 [SPARC] serial: Make sure sysfs nodes get named correctly.
Because we play this trick where we use ttyS? in increasing minor
numbers for different sunfoo.c drivers, we have to inform the TTY
layer of this.

Do so by setting the tty->name_base appropriately.

Probably there should be a generic way to do this in the serial core,
but for now...

David S. Miller 843dfb4d99 [SPARC64] sunhv: Fix locking in sunhv_start_tx()
Caller takes the lock already.

Also, fixup the poll loop in sunhv_break_ctl().  Just
like in console write, we udelay(2) and use a loop
limit of 1000000 iterations.

David S. Miller 135066a211 [SPARC64] sunhv: Support SYSRQ properly.
By calling uart_handle_break().  We'll still do the
"sun_do_break()" handling if the user gives two

We should probably do this in the other Sparc serial

David S. Miller d5a2aa241a [SPARC64] sunhv: Bug fixes.
Add udelay to polling console write loop, and increment
the loop limit.

Name the device "ttyHV" and pass that to add_preferred_console()
when we're using hypervisor console.

Kill sunhv_console_setup(), it's empty.

Handle the case where we don't want to use hypervisor console.
(ie. we have a head attached to a sun4v machine)

Pavel Machek d5f735e52f [PATCH] serial core: work around sub-driver bugs
We're presently getting oopses because Bluetooth (and possibly other) drivers
are calling core functions after things have been shut down.

So rather than oopsing, let's drop a warning then take avoiding action, so the
machine survives.  Once all the sub-drivers are fixed up we can remove the
take-avoiding-action part.

Russell King fd401aee62 [SERIAL] Remove incorrect code from ioc4 serial driver
Serial drivers in general should not write uart_info->flags - they're
private to serial_core.  Serial drivers have no need to fiddle with
tty->alt_speed, nor manipulate TTY_IO_ERROR in tty->flags.  Fix the
ioc4 serial driver for both these points by simply removing the
offending code.

Atsushi Nemoto 9c0f4755bd [SERIAL] initialize spinlock for port failed to setup console
It seems serial_core intend to initialize port->lock just once for each
ports.  This is done in uart_set_options() for console, and in
uart_add_one_port() for other ports.  But there is a case the port->lock is
not initialized by serial_core.  If the setup function for the console was
failed, it will not call uart_set_options() but the port is marked as
console (uart_console(port) returns 1).  It can happen if console was PCI
port which can not detected at the time of register_console.

This patch is to initialize port->lock for such console port.  With this
change, most of spin_lock_init() (some of them are labeled "Temporary
fix.") in low-level serial drivers can be omitted.
