* [SERIAL] sunhv: Convert to of_driver layer.David S. Miller2006-06-301-95/+71
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [PATCH] devfs: Remove devfs support from the serial subsystemGreg Kroah-Hartman2006-06-261-1/+0
| | | | | | Also fixes all serial drivers. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [SPARC64]: Convert sun4v virtual-device layer to in-kernel PROM device tree.David S. Miller2006-06-231-17/+18

* [SPARC] serial: Make sure sysfs nodes get named correctly.David S. Miller2006-03-201-0/+1
| | | | | | | | | | | | | 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... Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] sunhv: Fix locking in sunhv_start_tx()David S. Miller2006-03-201-6/+2
| | | | | | | | | | 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. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] sunhv: Support SYSRQ properly.David S. Miller2006-03-201-0/+2
| | | | | | | | | | | By calling uart_handle_break(). We'll still do the "sun_do_break()" handling if the user gives two breaks in a row. We should probably do this in the other Sparc serial drivers too. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix OOPS on sunhv interrupts.David S. Miller2006-03-201-16/+36
| | | | | | | | | Until the uart is openned, port->info is NULL. Also, init the port->irq properly and give a non-zero port->membase so that the uart device reporting is done. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Decode virtual-devices interrupts correctly.David S. Miller2006-03-201-10/+4
| | | | | | Need to translate through the interrupt-map{,-mask] properties. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] sunhv: Bug fixes.David S. Miller2006-03-201-15/+10
| | | | | | | | | | | | | | | 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) Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] sunhv: Use virtual-devices layer to get interrupt.David S. Miller2006-03-201-6/+67

* [SPARC64]: Add SUN4V Hypervisor Console driver.David S. Miller2006-03-201-0/+481
Since it can do things like BREAK and HUP, we implement this as a serial uart driver. This still needs interrupt probing code, as I haven't figured out how interrupts will work or be probed for on SUN4V yet. Signed-off-by: David S. Miller <davem@davemloft.net>
