a9ecdc0fdc ("of/irq: Fix lookup to use 'interrupts-extended' property
first") updated the description to say that:
- Both 'interrupts' and 'interrupts-extended' may be present
- Software should prefer 'interrupts-extended'
- Software that doesn't comprehend 'interrupts-extended' may use
'interrupts'
But there is still a paragraph at the end that prohibits having both and
says 'interrupts' should be preferred.
Remove the contradictory text.

The patch implements the OPAL rtc driver that binds with the rtc
driver subsystem. The driver uses the platform device infrastructure
to probe the rtc device and register it to rtc class framework. The
'wakeup' is supported depending upon the property 'has-tpo' present
in the OF node. It provides a way to load the generic rtc driver in
in the absence of an OPAL driver.
The patch also moves the existing OPAL rtc get/set time interfaces to the
new driver and exposes the necessary OPAL calls using EXPORT_SYMBOL_GPL.

drm/tegra: Changes for v3.19-rc1
The highlights in this pull request are:
* IOMMU support: The Tegra DRM driver can now deal with discontiguous
buffers if an IOMMU exists in the system. That means it can allocate
using drm_gem_get_pages() and will map them into IOVA space via the
IOMMU API. Similarly, non-contiguous PRIME buffers can be imported
from a different driver, which allows better integration with gk20a
(nouveau) and less hacks.
* Universal planes: This is precursory work for atomic modesetting and
will allow hardware cursor support to be implemented on pre-Tegra114
where RGB cursors were not supported.
* DSI ganged-mode support: The DSI controller can now gang up with a
second DSI controller to drive high resolution DSI panels.
Besides those bigger changes there is a slew of fixes, cleanups, plugged
memory leaks and so on.

Pull libata fixes from Tejun Heo:
"The most notable is the revert of lock splitting optimization in ahci.
This also made the IRQ handling threaded even when there's only one
IRQ in use. The conversion missed IRFQ_SHARED leading to screaming
IRQs problem in some cases and the threaded IRQ handling showed
performance regression in some LKP test cases. The changes are
reverted for now. It'll probably be retried once threaded IRQ
handling is removed from ahci.
Other than that, there's one fix for ahci and several patches adding
device IDs"

Since simplefb nodes do not relate directly to hw typically they have been
placed in the root of the devicetree. As the represent runtime information
having them as sub-nodes of /chosen is more logical, specify this.
Also specify when to set the chosen stdout-path property to a simplefb node.
For reliable handover to a hardware specific driver, that driver needs to
know which simplefb to unregister when taking over, specify how the hw driver
can find the matching simplefb node.
Last add some advice on how to fill and use simplefb nodes from a firmware
pov.
