Florian Fainelli 575e93f7b5 ARM: orion: Register DSA switch as a MDIO device
Utilize the ability to pass board specific MDIO bus information towards a
particular MDIO device thus allowing us to provide the per-port switch layout
to the Marvell 88E6XXX switch driver.

Since we would end-up with conflicting registration paths, do not register the
"dsa" platform device anymore.

Note that the MDIO devices registered by code in net/dsa/dsa2.c does not
parse a dsa_platform_data, but directly take a dsa_chip_data (specific
to a single switch chip), so we update the different call sites to pass
this structure down to orion_ge00_switch_init().

Arnd Bergmann fe158a17c1 ARM: orion: simplify orion_ge00_switch_init
One of the last users of NO_IRQ on ARM is the switch initialization
code on orion5x, which sometimes passes a GPIO based IRQ number.

However, the driver doesn't actually use this number, and according
to Andrew Lunn never will do it for non-DT based machines, so
we can simply drop the irq argument.

Simplifying it further, we can also drop the static platform_device
and instead call platform_device_register_data(), which in turn
lets us mark the platform_data structures as __initdata and slightly
reduce the memory consumption.

Arnd Bergmann c22c2c6008 ARM: orion5x: clean up mach/*.h headers
This is a simple move of all header files that are no longer
included by anything else from the include/mach directory
to the platform directory itself as preparation for
multiplatform support.

The mach/uncompress.h headers are left in place for now,
and are mildly modified to be independent of the other
headers. They will be removed entirely when ARCH_MULTIPLATFORM
gets enabled and they become obsolete.

Rather than updating the path names inside of the comments
of each header, I delete those comments to avoid having to
update them again, should they get moved or copied another
time.

Arnd Bergmann 5cdbe5d23a ARM: orion: use SPARSE_IRQ everywhere
As a preparation for multiplatform support, this moves all the
code using plat-orion over to use sparse irq support, which is
enabled implicitly for multiplatform.

In particular, the hardcoded NR_IRQS macro gets replaced with
a machine specific one that is set in the machine descriptor
in order to set up a static mapping for all legacy interrupts.

to switch to use it instead of the current name based scheme.

This will allow to deprecate the name based API, once every

Thomas Petazzoni 5d1190ea69 arm: mach-orion5x: convert to use mvebu-mbus driver
This commit migrates the mach-orion5x platforms to use the mvebu-mbus
driver and therefore removes the Orion5x-specific addr-map code.

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

We also convert a number of orion5x_setup_xyz_win() calls to the
appropriate mvebu_mbus_add_window() calls, as each board was doing its
own setup for the NOR window or other devices. Ultimately, those
devices will be probed from the DT.

The common address decoding windows are now registered in the
orion5x_setup_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.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
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:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Russell King daeb4c0c3b ARM: PCI: get rid of pci_std_swizzle()
Most PCI implementations use the standard PCI swizzle function, which
handles the well defined behaviour of PCI-to-PCI bridges which can be
found on cards (eg, four port ethernet cards.)

Rather than having almost every platform specify the standard swizzle
function, make this the default when no swizzle function is supplied.
Therefore, a swizzle function only needs to be provided when there is
something exceptional which needs to be handled.

This gets rid of the swizzle initializer from 47 files, and leaves us
with just two platforms specifying a swizzle function: ARM Integrator
and Chalice CATS.

Ralf Baechle d5341942d7 PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.
Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.

Lennert Buytenhek ac840605f3 mv643xx_eth: remove force_phy_addr field
Currently, there are two different fields in the
mv643xx_eth_platform_data struct that together describe the PHY
address -- one field (phy_addr) has the address of the PHY, but if
that address is zero, a second field (force_phy_addr) needs to be
set to distinguish the actual address zero from a zero due to not
having filled in the PHY address explicitly (which should mean
'use the default PHY address').

If we are a bit smarter about the encoding of the phy_addr field,
we can avoid the need for a second field -- this patch does that.

Lennert Buytenhek 81600eea98 mv643xx_eth: use auto phy polling for configuring (R)(G)MII interface
The mv643xx_eth hardware has a provision for polling the PHY's
MII management registers to obtain the (R)(G)MII interface speed
(10/100/1000) and duplex (half/full) and pause (off/symmetric)
settings to use to talk to the PHY.

The driver currently does not make use of this feature.  Instead,
whenever there is a link status change event, it reads the current
link parameters from the PHY, and programs those parameters into
the mv643xx_eth MAC by hand.

This patch switches the mv643xx_eth driver to letting the MAC
auto-determine the (R)(G)MII link parameters by PHY polling, if there
is a PHY present.  For PHYless ports (when e.g. the (R)(G)MII
interface is connected to a hardware switch), we keep hardcoding the
MII interface parameters.
