Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68knommu arch update from Greg Ungerer: "Quite a varied set of changes this time. - A little more merge cleanup, this time the assembler entry code. - New sub-architecture support for the ColdFire 5251/5253 and 5441x CPU families. - Specific clk support code for the ColdFire 520x and 532x CPU familes. - Refactoring of the ColdFire GPIO support. - PCI bus support for some ColdFire CPUS that have PCI hardware (54xx family). This showed up a few problems with ColdFire cache, allocating coherent memory and bi-directional DMA support. Fixes for those too." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (21 commits) m68k: allow PCI bus to be enabled for ColdFire m54xx CPUs m68k: add PCI bus code support for the ColdFire M54xx SoC family m68k: add IO access definitions to support PCI on ColdFire platforms m68k: add PCI bus support definitions for the ColdFire M54xx SoC family m68k: common PCI support definitions and code m68k: add support for DMA_BIDIRECTIONAL in dma support functions m68k: fix ColdFire clear cache operation m68k: use simpler dma_alloc_coherent() for ColdFire CPUs m68knommu: platform support for 8390 based ethernet used on some boards m68knommu: Add clk definitions for m532x. m68knommu: Add clk definitions for m520x. m68knommu: Add rtc device for m5441x. m68knommu: add definitions for the third interrupt controller on devices that don't have a third interrupt controller. m68knommu: Add support for the Coldfire m5441x. m68knommu: use MCF_IRQ_PIT1 instead of MCFINT_VECBASE + MCFINT_PIT1 coldfire-qspi: Add support for the Coldfire 5251/5253. m68knommu: Add support for the Coldfire 5251/5253 m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate mcf_gpio_chips. m68k: merge the MMU and non-MMU versions of the entry.S code m68k: use jbsr to call functions instead of bsrl ...
