Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68knommu arch updates from Greg Ungerer: "Most of it is a cleanup of the ColdFire hardware header files. We have had a few occurrances of bugs caused by inconsistent definitions of peripheral addresses. These patches make them all consistent, and also clean out a bunch of old crap. Overall we remove about 1000 lines." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (27 commits) m68knommu: fix inconsistent formating in ColdFire 5407 definitions m68knommu: fix inconsistent formating in ColdFire 5307 definitions m68knommu: fix inconsistent formating in ColdFire 527x definitions m68knommu: fix inconsistent formating in ColdFire 5272 definitions m68knommu: fix inconsistent formating in ColdFire 523x definitions m68knommu: clean up ColdFire 54xx General Timer definitions m68knommu: clean up Pin Assignment definitions for the 54xx ColdFire CPU m68knommu: fix multi-function pin setup for FEC module on ColdFire 523x m68knommu: move ColdFire slice timer address defiens to 54xx header m68knommu: use read/write IO access functions in ColdFire m532x setup code m68knommu: modify ColdFire 532x GPIO register definitions to be consistent m68knommu: remove a lot of unsed definitions for 532x ColdFire m68knommu: use definitions for the ColdFire 528x FEC multi-function pins m68knommu: remove address offsets relative to IPSBAR for ColdFire 527x m68knommu: remove unused ColdFire 5282 register definitions m68knommu: fix wrong register offsets used for ColdFire 5272 multi-function pins m68knommu: make ColdFire 5249 MBAR2 register definitions absolute addresses m68knommu: make remaining ColdFire 5272 register definitions absolute addresses m68knommu: make ColdFire Park and Assignment register definitions absolute addresses m68knommu: make ColdFire Chip Select register definitions absolute addresses ...
