Stephen Boyd reworked some Qualcomm USB code earlier this year.
The result requires a few different config options to be enabled
in order for the USB on the DragonBoard 410c to continue working,
but these were never added to arm64 "defconfig". As a result, USB
on that board stopped working during the v4.13-rc1 merge window.
Re-enable this functionality by setting the needed config options
in the arm64 "defconfig" file.

The new bus driver causes a harmless compile-time warning when
CONFIG_PM is disabled:
drivers/bus/ti-sysc.c:440:12: error: 'sysc_runtime_resume' defined but not used [-Werror=unused-function]
static int sysc_runtime_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~~
drivers/bus/ti-sysc.c:421:12: error: 'sysc_runtime_suspend' defined but not used [-Werror=unused-function]
static int sysc_runtime_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~~~~
This marks the two unused functions as __maybe_unused to shut up
that warning.

A bugfix for the SMP case broke the build for the UP case:
arch/arm/mach-shmobile/headsmp-apmu.o: In function `shmobile_boot_apmu':
(.text+0x34): undefined reference to `secondary_startup'
The assembler file mixes code that is used for SMP with code
that we also need on a single-CPU build, so I'm leaving it
always enabled in the Makefile, but enclose the SMP code
in an #ifdef.

We can handle the sysc interconnect target module in a generic way
for many TI SoCs. Initially let's just enable runtime PM with
autosuspend, and probe the children. This can already be used for
idling interconnect target modules that don't have any device driver
available for the child devices.
For now, the "ti,hwmods" custom binding is still required. That will
be eventually deprecated in later patches. And more features will be
added, such as parsing for sysc capabilities so we can continue
removing the legacy platform data.

We can populate the legacy resources needed by dma and smartreflex
from device tree in omap_device_build().
There should be no need to do this for other devices, and eventually
these two remaining users will be gone too. The legacy dma will be
dropped when the remaining users have been converted to use the
dmaengine driver, and smartreflex can now become just a regular
device driver with a few pdata callbacks.
This is needed in order to remove remaining device dma, irq and io
resources from the interconnect code.
And while at it, let's simplify things by removing otherwise
unused omap_device_build_ss() as we will never call it for more
than one hwmod.

When removing legacy platform data for IO ranges for the hwmod
interconnect code, we still need to support the "ti,hwmods"
property.
And as we're going to use a generic sysc device driver to handle the
interconnect target instances, we can parse the information needed
for legacy "ti,hwmods" IO range from the dts. It's always the first
range the interconnect target module provides.
Note that we want to parse the range instead of the first child
device IO regs as the child device may not always be defined.
The child IP device node may not exist in cases where there is no
driver binding for the device, or when the child IP block may not
even be functional for some SoC revisions. But the IO range of the
interconnect target module is always known.

The TRM has marked dra7 SmartReflex as reserved and we should not
touch those registers as pointed out by Nishanth Menon <nm@ti.com>.
We do still want to idle the related interconnect target modules on
init though.
Let's do this by only configuring the generic interconnect target modules
and not add the child SmartReflex devices.

On omap4 we are missing dts nodes for several interconnect target
modules that we are idling on init. This currently works with the
legacy platform data still around.
To fix this, let's add the interconnect target modules so we can
idle the unused interconnect target module on init.
Also note that adding the interconnect target module node does not
necessarily mean that there is a driver available for the child IP
block, or that the child IP block is even functional.
In the SGX case, the PowerVR driver is closed source. And McASP on
omap4 has at least the TX path disabled and is not supported by the
davinci-mcasp driver. For AESS there is old Android 3.4 kernel
driver available.
For smarflex, we are still probing with platform data and the
driver needs more work before we can add the device ip child nodes.
And finally, we're not yet using the interconnet ranges. I will
be posting separate patches for those later on.
