Hi Ricardo,
the commit message is misleading me. If I build something with ACPI or DT
support, then modinfo will show all modalias information for ACPI and DT
compatible strings. What else does udev/modprobe actually need? Is
something broken with the modalias export?

As suggested in the commit message we have added the device tree support,
proper bindings and we moved the driver into the correct folder.
Moreover we made some changes like use of relaxed IO accesor,
implement sched_clock, delay_timer and reduce the clockevents min_delta.

Like cmpxchg(), xa_cmpxchg will only store to the index if the current
entry matches the old entry. It returns the current entry, which is
usually more useful than the errno returned by radix_tree_insert().
For the users who really only want the errno, the xa_insert() wrappe

This function frees all the internal memory allocated to the xarray
and reinitialises it to be empty.

Now the page cache lookup is using the XArray, let's convert this
regression test from the radix tree API to the XArray so it's testing
roughly the same thing it was testing before.

These two functions move the xas index by one position, and adjust the
rest of the iterator state to match it. This is more efficient than
calling xas_set() as it keeps the iterator at the leaves of the tree
instead of walking the iterator from the root each time.

Slight change of strategy here; if we have trouble getting hold of a

There's no direct replacement for radix_tree_for_each_contig()

open-code a loop using xas_next(). This removes the only user of

This iterator iterates over each entry that is stored in the index or
indices specified by the xa_state. This is intended for use for a
conditional store of a multiindex entry, or to allow entries which are
about to be removed from the xarray to be disposed of properly.
