* TTY: amiserial no longer needs serialPJiri Slaby2012-03-081-49/+0
| | | | | | | | | | amiserial is the last user of serialP.h. Let's move struct serial_state directly to amiserial and remove serialP crap from includes. Finally, remove the header from the tree completely.

* TTY: amiserial, stop using serial_state->{irq,type,line}Jiri Slaby2012-03-081-3/+0
| | | | | | | | | * instead of line, use tty->index or iterator... * irq and type are left unset. So get rid of them. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | Let's do a spin-off of serial_state structure with only needed elements. And remove serialP crap from includes.

* TTY: amiserial/simserial, use flags from tty_portJiri Slaby2012-03-081-1/+0
| | | | | | | | | | | This changes flags' type to ulong which is appropriate for all the set/clear_bits performed in the drivers..

* TTY: amiserial/simserial, use count from tty_portJiri Slaby2012-03-081-1/+0
| | | | | | | | | | | Nothing special. Just remove count from serial_state and change all users to use tty_port.

* TTY: amiserial/simserial, use close delays from tty_portJiri Slaby2012-03-081-2/+0
| | | | | | | | | | | Note that previously simserial set the delay to 0. So we preserve that. BUT, is it correct?

* TTY: amiserial/simserial, use tty_portJiri Slaby2012-03-081-5/+2
| | | | | | | | | | | | Add tty_port to serial_state and start using common tty port members from tty_port in amiserial and simserial. The rest will follow one by one.

* TTY: serialP, merge serial_state and async_structJiri Slaby2012-03-081-7/+7
| | | | | | | | | | | | | | | This is the final step to get rid of the one of the structures. A further cleanup will follow. And I struct serial_state deserves cease to exist after a switch to tty_port too. While changing the lines, it removes also pointless tty->driver_data casts.

* TTY: simserial, remove support of shared interruptsJiri Slaby2012-03-081-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It never worked there. The ISR was never written for that kind of stuff. So remove all that crap with a hash of linked lists and pass the pointer directly to the ISR. BTW this answers the question there: * I don't know exactly why they don't use the dev_id opaque data * pointer instead of this extra lookup table -> Because they thought they will support more devices bound to a single interrupt w/o IRQF_SHARED. They would need exactly the hash there. What I don't understand is rebinding of the interrupt in the shutdown path. They perhaps meant to do just synchronize_irq? In any case, this is all gone and free_irq there properly. By removing the hash we save some bits (exactly NR_IRQS * 8 bytes of .bss and over a kilo of .text): before: text data bss dec hex filename 19600 320 8227 28147 6df3 ../a/ia64/arch/ia64/hp/sim/simserial.o after: text data bss dec hex filename 18568 320 28 18916 49e4 ../a/ia64/arch/ia64/hp/sim/simserial.o Note that a shared interrupt could not work too. request_irq requires data parameter to be non-NULL. So the whole IRQ_T exercise was pointless. Finally, this helps us remove another two members of async_struct :).

* TTY: simserial/amiserial, use one instance of other membersJiri Slaby2012-03-081-5/+0
| | | | | | | | | | | | | | | | | | | This means: * close_delay * closing_wait * line * port * xmit_fifo_size This actually fixes a bug in amiserial. It initializes one and uses the other of the close delays. Yes, duplicating structure members is evil.

* TTY: amiserial, remove tasklet for tty_wakeupJiri Slaby2012-03-081-8/+0
| | | | | | | | | | | | | | tty_wakeup is safe to be called from all contexts. No need to schedule a tasklet for that. Let's call it directly like in other drivers. This allows us to kill another member of async_struct structure. (If we remove the dummy uses in simserial.)

* TTY: serialP, remove unused materialJiri Slaby2012-03-081-59/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | First, remove unused macro and rs_multiport_struct structure. Nobody uses them at all. Further, the 2 drivers (they are below) which use the rest of structures from serialP.h (async_struct and serial_state) do not use all the members. Remove the members: * which are unused or * which are only initialized and never used for something real. Everybody should avoid the structures with a looong distance. Finally, remove the ALPHA kludge MCR quirks. They are 1:1 copy from 8250.h. No need to redefine them here.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
