Most ITS commands do operate on a collection object, and require
a SYNC command to be performed on that collection in order to
guarantee the execution of the first command.
With GICv4 ITS, another set of commands perform similar operations
on a VPE object, and a VSYNC operations must be executed to guarantee
their execution.
Given the similarities (post a command, perform a synchronization
operation on a sync object), it makes sense to reuse the same
mechanism for both class of commands.
Let's start with turning its_send_single_command into a huge macro
that performs the bulk of the work, and a set of helpers that
make this macro usable for the GICv3 ITS commands.

When assigning an interrupt to a vcpu, it is not unlikely that
the level of the hierarchy implementing irq_set_vcpu_affinity
is not the top level (think a generic MSI domain on top of a

In such a case, let's iterate over the hierarchy until we find
an irqchip implementing it.

Seems that on omap3 enabling a crtc without any planes causes a sync
lost flood. This only happens on the first enable, and after that it
works. This looks like an HW issue and it's unclear why this is
happening or how to fix it.
This started happening after 897145d0c7
("drm/omapdrm: Move commit_modeset_enables() before commit_planes()")
which, as a work-around, changed omapdrm first to do the modeset enable,
and plane set only after that. This WA should be fine on all DSS
versions, but apparently OMAP3 DSS is an exception.
This patch reverts that work-around for OMAP3 DSS.

7d267f068a ("drm/omap: work-around for

calculated. While the new way should work fine for all the PLLs, it
breaks omap5 PLLs. The issues seen are rather odd: seemed that the
output clock rate is half of what we asked. It is unclear what's causing
there issues.
As a work-around this patch adds a "errata_i886" flag, which is set only
for DRA7's PLLs, and the PLL setup is done according to that flag.

xdp_do_redirect_map() helper can be static since only used out of filter.c
file. Drop the goto in xdp_do_generic_redirect() and only return errors
