According to the ADE7758 datasheet the minimum time between read command
(that is, a write to communication register) and data read must not be
less than 4us.

Next patch will remove the current adis16350 driver.
These should have been merged a long time ago, but there we are.
V3: rebase fixup + add missing extend_name for supply on adis16350
V2: Move to single IIO_CHAN macro + use the new extend_name
to make the naming of the temperature sensors contain x, y, z
rather than messing with modifiers. This a very weird case
and I don't want temperature to use axial modifiers.

V3: Get rid of separate interrupt pool. This is well handled
by irq_get_descs and irq_free_descs. Two functions I simply
wasn't aware of previously. Thus the allocation for a given
trigger is now handled by core code rather than us reinventing
the wheel.
V2: Stop silly name duplication.
Move pool handling to industrialio-trigger as that is the only user.
Changed over to using irq_modify_status rather than the arm
specific set_irq_flags as per Thomas Gleixner's suggestion.
