The Page Request Interface (PRI) is an optional PCIe feature. As such, a
SMMU would not need to handle it if the PCIe host bridge or the SMMU
itself do not implement it. Also an SMMU could be connected to a platform
device, without any PRI functionality whatsoever.
In all cases there would be no SMMU PRI queue interrupt to be wired up
to an interrupt controller.
At the moment, with the "eventq,gerror,priq,cmdq-sync" order, we
would need to sacrifice the command queue sync interrupt as well, which
might not be desired.

Relax the binding to allow specifying certain useful combinations of
wired interrupts, for instance just the "gerror" interrupt, or omitting
both "pri" and "cmdq-sync".

Let's update the TI timer binding to use yaml. As this binding is specific
to the TI dual-mode timers also known as dm-timers, let's use file name
ti,timer-dm.yaml to avoid confusion with other timers.

We add checks for the deprecated ti,hwmods property as done for other TI
device driver bindings earlier.

We also correct the issue with the old binding that was out of date for
several properties.

The am43 related timers are undocumented, but compatible with the am3
timers. Let's add the am43 timers too.

The dm814 and dm816 timers are missing, let's add them.

Some timers on some SoCs are dual mapped, like the ABE timers on omap4
and 5. The reg property maxItems must be updated to 2.

The timer clocks can be managed by the parent interconnect target module
with no clocks assigned for the timer node. And in some cases, the SoC may
need to configure additional system clock for the timer in addition to the
functional clock.

The clock names are optional and not specific to the comptible property.
For example, dra7 timers on l3 interconnect do not need clock-names, while
the timers on dra7 l4 interconnect need them with both being compatible
with ti,omap5430-timer.
