Multi-platform support implies all these options are already selected and
individual platforms don't need to select them.

This patch adds support for the BCM5301X/BCM470X SoCs with an ARM CPUs.
Currently just booting to a shell is working and nothing else, no
Ethernet, wifi, flash, ...
I have some pending patches to make Ethernet work for this device.
Mostly device tree support for bcma is missing.

This SoC is used in small office and home router with Broadcom SoCs
it's internal name is Northstar. This code should support the BCM4707,
BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or
two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers,
4 Gigabit Ethernet MACs and a USB 3.0 host controller.

This SoC uses a dual core CPU, but this is currently not implemented.
More information about this SoC can be found here:

Move the bcm2835 board file into the mach-bcm directory. This allows us
to get rid of the mach-bcm2835 directory with the associated Kconfig

Multi-platform requires various kconfig options to be selected, so
platforms don't need to select them individually.

Adds pinctrl driver for Broadcom Capri (BCM281xx) SoCs.

v4: - PINCTRL selected in Kconfig, PINCTRL_CAPRI selected in bcm_defconfig
    - make use of regmap
    - change CAPRI_PIN_UPDATE from macro to inline function.
    - Handle pull-up strength arg in Ohm instead of enum
v3: Re-work driver to be based on generic pin config. Moved config selection
    from Kconfig to bcm_defconfig.
v2: Use hyphens instead of underscore in DT property names.

Currently ARCH_BCM has been used for Broadcom
Mobile V7 based SoCs. In order to allow other Broadcom
SoCs to also use mach-bcm directory and files, this patch
renames the original ARCH_BCM to ARCH_BCM_MOBILE, and
uses ARCH_BCM to define any Broadcom chip residing
in mach-bcm directory.

This adds support for the Broadcom timer, used in the following SoCs:
BCM11130, BCM11140, BCM11351, BCM28145, BCM28155

Updates from V6:
- Split DT portion into a separate patch

Updates from V5:
- Rebase to latest arm-soc/for-next

Updates from V4:
- Switch code to use CLOCKSOURCE_OF_DECLARE

Updates from V3:
- Migrate to 3.9 timer framework updates

Updates from V2:
- prepend static fns + fields with kona_

Updates from V1:
- Rename bcm_timer.c to bcm_kona_timer.c
- Pull .h into bcm_kona_timer.c
- Make timers static
- Clean up comment block
- Switched to using clockevents_config_and_register
- Added an error to the get_timer loop if it repeats too much
- Added to Documentation/devicetree/bindings/arm/bcm/bcm,kona-timer.txt
- Added missing readl to timer_disable_and_clear

Note: bcm,kona-timer was kept as the 'compatible' field to make it
specific enough for when there are multiple bcm timers (bcm,timer is
too generic).

In drivers/gpio/Kcong, ARCH_REQUIRE_GPIOLIB selects GPIOLIB which in
turn selects GENERIC_GPIO.  So GENERIC_GPIO will be selected
automatically for those platforms that select ARCH_REQUIRE_GPIOLIB.

Remove the redundant 'select GENERIC_GPIO' for platforms that already
select ARCH_REQUIRE_GPIOLIB at either mach or plat level.

In order to start upstreaming Broadcom SoC support, create
a starting hierarchy, arch and dts files.
The first support SoC family that is planned is the
BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile
SoC cores.
This code is just the skeleton code for get the machine upstreamed. It
has been made MULTIPLATFORM compatible.
Next steps
----------
Upstream a basic set of drivers - sufficient for a console boot to
ramdisk. These will includer timer, gpio, i2c drivers.
After this basic set, we will proceed with a more comprehensive set
of drivers for the 281XX SoC family.

v2 patch mods
--------
 - Remove l2x0_of_init call as there were problems with the code.
   A separate patch will be submitted with cache init code
 - Rename capri files and refs to bcm281xx-based names
 - Add bcm281xx binding doc
 - various misc cleanups

v3 patch mods
-------------
 - Remove extra #include lines
 - Remove remaining references to capri
 - dt uart chipset string added
 - cleaned up chip # references

v4 patch mods
-------------
 - swap order of compatible definitions for uart
 - fix typo

v5 patch mods
-------------
 - Rename bcm281xx to bcm11351 in dts+code,
   leaving references to bcm281xx only in help+comments.

v6 patch mods
-------------
 - fix typo in uart 'compatible' string
