* m68k: common PCI support definitions and codeGreg Ungerer2012-07-175-0/+122
| | | | | | | | | Basic set of definitions and support code required to turn on CONFIG_PCI for the m68k architecture. Nothing specific to any PCI implementation in any m68k class CPU hardware yet. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
* m68k: add support for DMA_BIDIRECTIONAL in dma support functionsGreg Ungerer2012-07-171-0/+1
| | | | | | | | | | | | | | | | The dma cache support functions do not currently support the direction flag DMA_BIDIRECTIONAL. If a driver passes this direction to dma_map_single or friends you will get console output like this: dma_sync_single_for_device: unsupported dir 0 For example when using the Intel e100 ethernet driver on a ColdFire platform with PCI bus. You will get a stream of these messages coming out. Modify the dma cache support code adding support for DMA_BIDIRECTIONAL. It is actioned by doing a cache push operation.

* m68k: fix ColdFire clear cache operationGreg Ungerer2012-07-172-1/+42
| | | | | | | | The code for clearing (invalidating) the ColdFire cache is actually performing a push operation. Add functions to clear the cache, and fix cache_clear() to call the appropriate clear cache function. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68k: use simpler dma_alloc_coherent() for ColdFire CPUsGreg Ungerer2012-07-161-2/+2
| | | | | | | | | | On all ColdFire platforms (whether MMU enabled or not) we want to use the simple page based dma_alloc_coherent. We don't want the virtual mapping version that is used on classic m68k setups. So modify the conditionals to use the existing simpler dma_alloc_coherent on all ColdFire and non-MMU builds.

* m68knommu: Add support for the Coldfire m5441x.Steven King2012-07-1615-24/+761
| | | | | | | | | | | | | | Add support for the Coldfire 5441x (54410/54415/54416/54417/54418). Currently we only support noMMU mode. It requires the PIT patch posted previously as it uses the PIT instead of the dma timer as a clock source so we can get all that GENERIC_CLOCKEVENTS goodness. It also adds some simple clk definitions and very simple minded power management. The gpio code is tweeked and some additional devices are added to devices.c. The Makefile uses -mv4e as apparently, the only difference a v4m (m5441x) and a v4e is the later has a FPU, which I don't think should matter to us in the kernel.

* m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate ↵Steven King2012-07-1618-551/+375
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mcf_gpio_chips. If we're not connecting external GPIO extenders via i2c or spi or whatever, we probably don't need GPIOLIB. If we provide an alternate implementation of the GPIOLIB functions to use when only on-chip GPIO is needed, we can change ARCH_REQUIRE_GPIOLIB to ARCH_WANTS_OPTIONAL_GPIOLIB so that GPIOLIB becomes optional. The downside is that in the GPIOLIB=n case, we lose all error checking done by gpiolib, ie multiply allocating the gpio, free'ing gpio etc., so that the only checking that can be done is if we reference a gpio on an external part. Targets that need the extra error checking can still select GPIOLIB=y. For the case where GPIOLIB=y, we can simplify the table of gpio chips to use a single chip, eliminating the tables of chips in the 5xxx.c files. The original motivation for the definition of multiple chips was to match the way many of the Coldfire variants defined their gpio as a spare array in memory. However, all this really gains us is some error checking when we request a gpio, gpiolib can check that it doesn't fall in one of the holes. If thats important, I think we can still come up with a better way of accomplishing that. Also in this patch is some general cleanup and reorganizing of the gpio header files (I'm sure I must have had a reason why I sometimes used a prefix of mcf_gpio and other times mcfgpio but for the life of me I can't think of it now).

* m68k: use jbsr to call functions instead of bsrlGreg Ungerer2012-07-161-2/+2
| | | | | | | | | | There is a few places that the m68k entry code uses the bsrl instruction to call other functions. That instruction is only supported on 68020 and higher CPU types.

* m68k: use some direct calls to ret_from_exception in entry codeGreg Ungerer2012-07-161-3/+3
| | | | | | | | | | | The ret_from_excption code is referenced by its function name, or by a label set at the start of its code. The non-MMU code can share some of this code if we make direct calls to ret_from_exception instead of the associated label. The effected function paths are: buserr, trap and ret_from_fork. So change these to branch directly to ret_from_exception. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to inactive domains') introduced possibility to add devices to inactive power domains and added pm_genpd_dev_need_restore() function which lets platform core to notify power domain core that the specified device must be restored (with its runtime_resume() callback) before first use. This patch adds the pm_genpd_dev_need_restore() call what brings back the suspend/resume behaviour for the client devices known from the previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM: EXYNOS: Hook up power domains to generic power domain infrastructure'). Client device drivers relay on that suspend/resume behaviour, thus this patch fixes runtime pm operation for client devices.
