[PATCHv3 0/5] ARM: mvebu: no I/O coherency on non-SMP and related updates

[Thomas Petazzoni]

Hello,

This series makes a number of updates to the I/O coherency code of
Marvell EBU platforms.

Changes since v2:

 - Drop patch "ARM: mvebu: add missing of_node_put() call in
   coherency.c" since it was merged.

 - Update "make the coherency_ll.S functions work with no coherency
   fabric" to use "reteq <reg>" instead of "moveq pc, <reg>", as
   suggested by Grégory Clement.

 - Update the comment in "disable I/O coherency on non-SMP situations
   on Armada 370/375/38x/XP" to give more details about what would be
   needed to get HW I/O coherency working on Armada 370, as suggested
   by Jason Cooper.

 - Added Acked-by from Grégory Clement as appropriate.

 - Added one patch to drop the Armada 375 Z1 workaround for I/O
   coherency, which removes a significant chunk of code from
   coherency.c.

 - Added two patches doing minor cleanup/updates to coherency.c

Changes since v1:

 - Rebased on top of v3.18-rc2.
 - Added some Fixes:/Cc: tags on the last patch to get it merged into
   the stable tree, as it fixes a real DT reference count leak.

Best regards,

Thomas Petazzoni
