Thomas Petazzoni 7d55490277 arm: mach-dove: convert to use mvebu-mbus driver
This commit migrates the mach-dove platforms to use the mvebu-mbus
driver and therefore removes the Dove-specific addr-map code.

The dove_init_early() function now initializes the mvebu-mbus driver
by calling mvebu_mbus_init().

The address decoding windows are now registered in the
dove_setup_cpu_wins() function. It is worth noting that the four PCIe
address decoding windows will ultimately no longer have to be
registered here: it will be done automatically by the PCIe driver once
Dove has been migrated to use the upcoming mvebu PCIe driver.

Linus Torvalds 1a32c58bb9 arm-soc: mvebu platform changes
This series contains changes for the Marvell EBU platforms (mvebu,
 orion, kirkwood, dove) that were not part of the first set of pull
 requests because of dependencies on the MMC tree, and being submitted
 a little late.
 
 Notable changes are:
 
 * More devices get moved out of board files into device tree
   descriptions. The remaining devices listed in there have patches
   that will get sent for 3.10, after which we can remove a lot of the
   board files entirely. We are doing the pinctrl and mmc drivers here,
   ethernet and PCI still remain.
 
 * SMP support for mvebu is improved with support for the
   local interrupt controller.
 
 * The Guruplug board file gets replaced with a DT description.
 
 Unfortunately, the dependency on the MMC tree turned out to be a much
 larger problem than expected, when the MMC maintainer rebased the patches
 in his tree that all of the patches in this branch are based on, which
 caused merge conflicts between the new and old versions of those patches.
 
 To work around the merge conflicts, this branch rebases all patches
 on top of the respective MMC patches that did get merged into 3.9.
 The patches are all identical to the versions that were part of
 linux-next, but have a new commit date.
 
 Merge conflicts:
 
 * in board-nsa310.c, the gpio.h inclusion was removed prematurely and
   put back as a bug fix earlier. With this series it is really not needed
   any more.
 
 * The patch to add rtc support was already applied by Andrew Morton,
   and conflicts with a second copy that was in this series, which adds
   a lot of other devices to arch/arm/boot/dts/armada-370-xp.dtsi.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

Russell King - ARM Linux 5d3df93542 Dove: Attempt to fix PMU/RTC interrupts
Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner.  The PMU is one such instance.

The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)

Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed.  If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing.  So, we need to do a read-modify-write
cycle to clear the asserted bit.

However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.

The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.)  The patch below at least stops us creating
new interrupts.

Thomas Petazzoni 73b39d4b44 arm: mach-dove: use plus instead of or for address definitions
Since we are going to use IOMEM() to define many base virtual
addresses, we can no longer use binary or to define the individual
register addresses ("binary or" arithmetic on pointers is not
allowed). Instead, use the more conventional plus operator to do so.

The binary or operators were actually not useful because the low-order
bits of the base address were always zero, so the usage of the binary
or operators was effectively identical to a plus operator.

However, select USB_ARCH_HAS_EHCI so that we can still have EHCI
support.
