ARM: OMAP2+: Populate DMTIMER errata when using device-tree
Currently the DMTIMER errata flags are not being populated when using
device-tree. Add static platform data to populate errata flags when
using device-tree.
Please note that DMTIMER erratum i767 is applicable to OMAP3-5 devices
as well as AM335x devices.
