Remove some remaining vestiges of the old hacks jsm had to work around the old
tty buffering. With the new tty buffering it simply doesn't matter any more.[michal.k.k.piotrowski@gmail.com: fix warning]

Enable wakeup from serial ports, make it run-time configurable over sysfs,
e.g.,echo enabled > /sys/devices/platform/serial8250.0/tty/ttyS0/power/wakeup
Requires
# CONFIG_SYSFS_DEPRECATED is not set
Following suggestions from Alan and Russell moved the may_wake_up checks
to serial_core.c. This time actually tested - it does even work. Could
someone, please, verify, that put_device after device_find_child is
correct?Also would be nice to test with a Natsemi UART, that can wake up the system,
if such systems exist.For this you just have to apply the patch below, issue the above "echo"
command to one of your Natsemi port, suspend and resume your system, and
verify that your Natsemi port still works. If you are actually capable of
waking up the system from that port, would be nice to test that as well.Signed-off-by: Guennadi Liakhovetski

The way the current CPM binding describes available multi-user (a.k.a.
dual-ported) RAM doesn't work well when there are multiple free regions,
and it doesn't work at all if the region doesn't begin at the start of
the muram area (as the hardware needs to be programmed with offsets into
this area). The latter situation can happen with SMC UARTs on CPM2, as its
parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
support moving it.It is now described with a muram node, similar to QE. The current CPM
binding is sufficiently recent (i.e. never appeared in an official release)
that compatibility with existing device trees is not an issue.The code supporting the new binding is shared between cpm1 and cpm2, rather
than remain separated. QE should be able to use this code as well, once
minor fixes are made to its device trees.Signed-off-by: Scott Wood

The existing OF glue code was crufty and broken. Rather than fix it,
it has been removed, and the serial driver now talks to the device tree
directly.The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms
are dropped from arch/ppc (which will hopefully be soon), and existing
arch/powerpc boards that I wasn't able to test on for this patchset get
converted (which should be even sooner).Signed-off-by: Scott Wood

in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp.
On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't
be used for arithmetric compare operations with virtual addresses
returned by cpm_dpram_addr. This patch changes the assignment to use
cpm_dpram_addr as well, like in cpm_uart_cpm2.h.Signed-off-by: Jochen Friedrich

This adds the option for the pmac_zilog driver to use the major/minor
numbers recently allocated specifically for it (/dev/ttyPZn) instead
of the /dev/ttySn numbers. The advantage of doing this is that it
allows the pmac_zilog and 8250 drivers to coexist. The disadvantage
of doing this is that it is a user-visible ABI change and it will
break existing working setups on powermacs, and could be confusing to
users.Signed-off-by: David Woodhouse

The kgdb console code requires uart_set_options() and friends, which
are only provided by the serial core when console support is enabled.
These were sitting under CONFIG_SH_KGDB and resulted in a link error
when console support wasn't enabled, work that by rolling the console
routines under CONFIG_SH_KGDB_CONSOLE, which they should have been
all along.Signed-off-by: Paul Mundt

* don't register irq until ->startup() (and release in ->shutdown()).
That avoids oopsen with the current tree when interrupt comes before we'd
set up the data structures for ttyb.
* handle console=ttyS... even when OBP talks to screen/keyboard
* register irq handler for each port, let kernel/irq/handle.c
call it for both if needed. Kills code duplication in sunsab_interrupt().
BTW, there'd been bitrot in it - ttya handling had stopped calling
check_status() on BRK (correctly), ttyb copy of that code had kept the
bogus call in that case.Signed-off-by: Al Viro
