serial/arc-uart: Miscll DT related updates (Grant's review comments)

2013-02-13T16:37:49+00:00

-replace "baud" with "current-speed"
-if uart alias doesn't exist in DT, don't abort, pick 0

serial/arc-uart: Fix section mistmatch

2013-01-18T01:20:09+00:00

Commit "serial/arc-uart: split probe from probe_earlyprintk" introduced
a build time warning:

"WARNING: vmlinux.o(.data+0x5baa0): Section mismatch in reference from
the variable early_arc_platform_driver to the function
.init.text:arc_serial_probe_earlyprintk()"

While at it - fixed another incorrectly placed initdata annotation.

TTY: switch tty_flip_buffer_push

2013-01-16T06:30:15+00:00

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.

Now, the one where most of tty_port_tty_get gets removed:
tty_flip_buffer_push.

IOW we also closed all the races in drivers not using tty_port_tty_get
at all yet.

Also we move tty_flip_buffer_push declaration from include/linux/tty.h
to include/linux/tty_flip.h to all others while we are changing it
anyway.

serial/arc-uart: switch to devicetree based probing

2013-01-16T06:16:05+00:00

* DT binding for arc-uart
* With alll the bits in place we can now use DT probing.

Note that there's a bit of kludge right now because earlyprintk portion
of driver can't use the DT infrastrcuture to get resoures/plat_data.
This requires some infrastructre changes to of_flat_ framework

serial/arc-uart: platform_data order changed

2013-01-16T06:15:48+00:00

* is_emulated is now 1st element, rather than last
* also tucked all platform data refs together

serial/arc-uart: split probe from probe_earlyprintk

2013-01-16T06:15:17+00:00

This is in preparation for devicetree based probing, where earlyprintk
won't have access to DT serial aliases which the normal probe would
absolutely rely on.

serial/arc-uart: Don't index with -ve platform_device->id

2013-01-16T06:15:17+00:00

probe routine could index into port[] with -ve index. The check in
arc_uart_init_one() was too late.

This came to light when trying to port driver to CONFIG_OF, where
bydefault of-core code sets -ve platform dev id and in absence of
DT serial aliases, driver would use the -ve index.
