There is a RCPM (Run Control/Power Management) in Freescale QorIQ
series processors. The device performs tasks associated with device
run control and power management.
The driver implements some features: mask/unmask irq, enter/exit low
power states, freeze time base, etc.

Originally the mpc85xx-pci-edac driver bound directly to the PCI
controller node.
Commit
905e75c46dba ("powerpc/fsl-pci: Unify pci/pcie initialization code")
turned the PCI controller code into a platform device. Since we can't
have two drivers binding to the same device, the EDAC code was changed
to be called into as a library-style submodule. However, this doesn't
work if the EDAC driver is built as a module.
Commit
8d8fcba6d1ea ("EDAC: Rip out the edac_subsys reference counting")
exposed another problem with this approach -- mpc85xx_pci_err_probe()
was being called in the same early boot phase that the PCI controller
is initialized, rather than in the device_initcall phase that the EDAC
layer expects. This caused a crash on boot.
To fix this, the PCI controller code now creates a child platform device
specifically for EDAC, which the mpc85xx-pci-edac driver binds to.

With all mxs-dma clients moved to use generic DMA helper, the code
left from generic DMA binding conversion can be removed now.

The bestcomm dma hardware, and some of its users like the FEC ethernet
component, is used in different FreeScale parts, including non-powerpc
parts like the ColdFire MCF547x & MCF548x families. Don't keep the
driver hidden in arch/powerpc where it is inaccessible for other arches.
.c files are moved to drivers/dma/bestcomm, while .h files are moved to
include/linux/fsl/bestcomm. Makefiles, Kconfigs and #include directives
are updated for the new file locations.
Tested by recompiling for MPC5200 with all bestcomm users enabled.

Rewrite mxs_dma_is_apbh and mxs_dma_is_apbx in order to support
other SoCs like imx6q and reform the platform_device_id for the
better further dt support.

Move the header to a more common place.
The mxs dma engine is not only used in mx23/mx28, but also used
in mx50/mx6q. It will also be used in the future chips.
Rename it to mxs-dma.h, and create a new folder include/linux/fsl/ to
store the Freescale's header files.
change mxs-dma driver, mxs-mmc driver, gpmi-nand driver, mxs-saif driver
to the new header file.
