Russell King 8523f61537 ARM: l2c: nomadik: convert to generic l2c OF initialisation
Remove the explicit call to l2x0_of_init(), converting to the generic
infrastructure instead.  This also allows us to eliminate the
.init_machine function as it is identical to the generic version.

Russell King 42708e37a3 ARM: l2c: nomadik: remove cache size override
The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP.  Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to
the L2 cache code.  Remove them so we can find out which really need
this.

Linus Walleij 6568eccd10 ARM: nomadik: get rid of explicit ethernet GPIO management
We used to set up the GPIO used for the SMC ethernet IRQ by
requesting the GPIO line explicitly. As we recently established
that specifying the GPIO controller as interrupt parent and
requesting one of its interrupts by reference should be enough,
we do away with this. Incidentally, the Nomadik GPIO chip driver
handles this just fine: the IRQ is set up and fired as expected.

Olof Johansson c884357ec6 Merge branch 'clk-of-init-v2_for-3.13' of https://github.com/shesselba/linux-dove into next/cleanup
From Sebastian Hasselbarth:

This is a patch set based on an RFC [1][2] sent earlier to provide
a common arch/arm init for DT clock providers. Currently, the call to
of_clk_init(NULL) to initialize DT clock providers is spread among several
mach-dirs. Since most machs require DT clocks initialized before timers,
no initcall can be used.

By adding of_clk_init(NULL) to arch/arm time_init(), we can remove all
mach-specific .init_time hooks that basically called of_clk_init and
clocksource_of_init.

In contrast to the RFC version, of_clk_init(NULL) is now only called if
no custom .init_time callback is set. This allows some machs to still
call clock init themselves, as not all can be converted now. Therefore,
this patch sets drops conversion of mach-mvebu and mach-zynq. New machs
that were introduced with v3.12-rc1 are also converted, except mach-u300
that requires clocks before irqs.

Sebastian Hesselbarth 74227e65f9 clk: nomadik: declare OF clock provider
Common clock framework allows to register clock providers to get called
on of_clk_init() by using CLK_OF_DECLARE. This converts nomadik clock
provider to make use of it and get rid of the mach specific clk init
call. As clocks require system reset controller base address to be
initialized each clock driver checks src_base and calls new
nomadik_src_init if required.

Linus Torvalds ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

Linus Walleij 2ad6e39867 ARM: nomadik: convert SMSC91x ethernet to device tree
This converts the SMSC91x ethernet controller to use device
tree. The existing solution from the board file, to request the
GPIO triggering the ethernet IRQ from the board file is kept
for the time being, but the GPIO number assignment is moved
over to the device tree.

This adds the FSMC NAND driver and flash partitions to the Nomadik

The only compatible string accepted by this driver is currently
"st,spear600-fsmc-nand" which is inappropriate for this system, so
this patch adds the compatible value "stericsson,fsmc-nand" as
well.

Linus Walleij d962117687 ARM: nomadik: bump the IRQ numbers again
Bump the IRQ numbers from offset at 1 (right above NO_IRQ)
to 32. This is the painful way to learn that if you're using
SPARSE_IRQ and avoid to define .nr_irqs in your machine,
the first 16 IRQs will be pre-allocated, and the IRQdomain
code (as the VIC core code before it) will then assume
that all IRQ descriptors are pre-allocated, and 16 of them
are - by somebody else. So mapping the IRQs will fail in
irq_create_mapping(). Moving the offset upward rids us of
this problem.

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.

Linus Walleij 694e33a7f4 ARM: plat-nomadik: move MTU, kill plat-nomadik
This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.

As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.

After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.
