hvc: Convert to using interrupts instead of opal events

2015-05-22T05:14:38+00:00

Convert the opal hvc driver to use the new irqchip to register for
opal events. As older firmware versions may not have device tree
bindings for the interrupt parent we just use a hardcoded hwirq based
on the event number.

tty: hvc: drop owner assignment from platform_drivers

2014-10-20T14:21:44+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

tty: Update hypervisor tty drivers to use core stdout parsing code.

2014-06-26T16:12:23+00:00

The evh_bytechan, hvc_opal and hvc_vio drivers all open code the parsing
of the stdout node in the device tree. This patch simplifies the driver
by removing the duplicated functionality.

tty/hvc_opal: Kick the HVC thread on OPAL console events

2014-04-07T00:34:27+00:00

The firmware can notify us when new input data is available, so
let's make sure we wakeup the HVC thread in that case.

drivers/tty/hvc: don't use module_init in non-modular hyp. console code

2014-02-07T16:40:54+00:00

The HVC_OPAL/RTAS/UDBG/XEN options are all bool, and hence their support
is either present or absent.  It will never be modular, so using
module_init as an alias for __initcall is rather misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.

Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups.  As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

Also the __exitcall functions have been outright deleted since
they are only ever of interest to UML, and UML will never be
using any of this code.

tty: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no
