[PATCH 0/5] tty: serial: Updates for altera_jtaguart driver

[Tobias Klauser]

This patchset adds updates taken from the Nios2 Linux port (currently
out-of-tree) repository to the altera_jtaguart driver.

And this time with the correct cover letter right away :-)

Tobias Klauser (5):
  tty: serial: altera_jtaguart: Don't use plain integer as NULL pointer
  tty: serial: altera_jtaguart: Remove unused function
    early_altera_jtaguart_setup
  tty: serial: altera_jtaguart: Support getting mapbase and IRQ from
    resources
  tty: serial: altera_jtaguart: Fixup type usage of port flags
  tty: serial: altera_jtaguart: Add device tree support

[PATCH 3/5] tty: serial: altera_jtaguart: Support getting mapbase and IRQ from resources

[Tobias Klauser]

This will make it easier to get the driver to support device tree. The
old platform data method is still supported though.

Also change the driver to use only one platform device per port.

After this series, I get the following build error:
	  CC [M]  drivers/tty/serial/altera_jtaguart.o
	  drivers/tty/serial/altera_jtaguart.c:485:3: error: unknown field ‘of_match_table’ specified in initializer

So I can't take them, sorry.

Care to fix this and resend them after testing them?

thanks,

Strange, I didn't get that one when compile testing against linux-next
on x86_64. Though it seems I didn't correctly test it on nios2 and I got
a compile error about a missing semicolon in the definition of
altera_jtaguart_match there.

So that might be the culprit for the above message too. I'll resend the
last PATCH of the series to fix that (and of course compile-test it
before).

Thanks a lot and sorry

It might be that the of_match_table patch is available in Grant's branch 
only, which is for v3.6.39. Maybe you can ask Grant to take this patch 5/5.

That explains it, thanks Thomas.

Greg, care to take only patches 1/5 to 4/5 for now? I'll resubmit 5/5
for the 2.6.39 merge window, unless Grant already wants to take this to
his tree.

I'm happy to take this patch if it doesn't depend on the first 4.
Alternately Greg, you could merge commit c9e358dfc "driver-core:
remove conditionals around devicetree pointers" from my
devicetree/test branch on git://git.secretlab.ca/git/linux-2.6.  I
won't be rebasing that commit and it is the first commit on top of
2.6.38-rc1.

The patch doesn't depend on the first 4, so you could take it if Greg
doesn't oppose.
