The definition of PMD_PAGE_ORDER denoting the number of base pages in the
second-level leaf page is already used by DAX and maybe handy in other

Hi,
This series addresses the power management for SAMA7G5 and also updates
the master clock prescaller and master clock divider drivers to accomodate
the requests at [1].
The power management part is implemented by adding
save_context()/restore_context() on each clock driver (patch 1/5). Since
Clock is not optional for users who call into dev_pm_opp_set_rate().
Remove the unnecessary checks.
While at it also drop the local variable for clk and use opp_table->clk
instead.

Add register definitions for SAMA7G5's master clock. These would be
also used by architecture specific power saving code. With this, update
also clk-master.c.

Until now the ->set_opp() helper (i.e. special implementation for
setting the OPPs for platforms) was implemented only to take care of
multiple regulators case, but going forward we would need that for other
use cases as well.
This patch prepares for that by allocating the regulator specific part
Add new trap action HARD_DROP, which can be used by the
drivers to register traps, where it's impossible to get
packet reported to the devlink subsystem by the device
driver, because it's impossible to retrieve dropped packet
from the device itself.
In order to use this action, driver must also

It is not necessary but it does not hurt, since we are going to add vmalloc
anyway at some
Add support for new HARD_DROP action, which is used for
trap hard drop statistics retrival. It's used whenever
device is unable to report trapped packet to the devlink
subsystem, and thus device could only state how many
packets have been dropped, without passing a packet
to the devlink subsystem

This patch adds bindings to support display and Image codec(jpeg) iommu
instance.
The iommu support for others would be added once finished tests with those
devices, such as a few signal processors, including VSP(video),
GSP(graphic), ISP(image), and camera CPP, etc.
