During the review process of the UniPhier System Bus driver
(drivers/bus/uniphier.c), the current binding of the System Bus
Controller turned out to be no good.  In order to use the driver,
some nodes in the device trees must be tweaked.  It would also have
impacts on the SMP code because the SMP related registers are
located in the System Bus Controller block.  This commit reworks
the smp_operations to support the new binding, but still supports
the old binding, too.

Samsung Exynos (and older platforms) improvements for v4.6:
1. Split out Exynos PMU driver implementation from arm/mach-exynos
   to the drivers/soc/samsung which will allow re-use of it on ARM64.
2. Use generic DT cpufreq driver on Exynos542x/5800.

Merge tag 'for-v4.6/omap-hwmod-b' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.6/soc

ARM: OMAP2+: second set of hwmod changes for v4.6

These patches add RTC support for the AM43xx, and add support for
the DRA7xx eDMA controller's TPCC, TPTC0, and TPTC1 IP blocks.
Also included is a workaround for PRCM hardreset control of the DRA7xx
PCIe subsystem.

Note that I do not have a DRA7xx board, and therefore cannot
test any patches for that SoC family.

Basic build, boot, and PM test logs can be found here:

http://www.pwsan.com/omap/testlogs/omap-hwmod-b-for-v4.6/20160301021258/

Add hwmod data for the eDMA blocks:
 - TPCC: Third-party channel controller
 - TPTC0: Third-party transfer controller 0
 - TPTC1: Third-party transfer controller 1

The TPCC's clock gating status follows the status of its clock and
power domain. This means that the hwmod code can not directly control
the TPCC enable/disable status.

All the generic L2 cache handling code is encapsulated by a
check if the L2 cache is enabled. If it's enabled already, the code
is skipped. The write to the L2-Cache controller from non-secure
world causes an imprecise external abort. This is needed in
scenarios where one of the cores runs an other OS, e.g. an RTOS.

i.MX only needs to select ARM_CPU_SUSPEND manually for the
very specific case that CONFIG_PM_SLEEP is disabled and imx6
is used with CONFIG_PM enabled for runtime PM.

If we are building a kernel only for CPUs that are not using
the cpu_suspend() helper, we otherwise get a harmless
build warning:

warning: (ARCH_MXC && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM &&

This moves the option to the SOC_IMX6 option that actually
requires it, in effect reverting commit f36b594f

 ("ARM:

meant as a cleanup and unintentionally caused this warning.
