Driver updates for ARM SoCs, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons. For the most part, this is now related to power management
controllers, which have not yet been abstracted into a separate
subsystem, and typically require some code in drivers/soc or arch/arm
to control the power domains.
Another large chunk here is a rework of the NVIDIA Tegra USB3.0
support, which was surprisingly tricky and took a long time to
get done.
Finally, reset controller handling as always gets merged through here
as well.

This patch adds support for MIPI DPHYs found in Exynos5420-compatible
(5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from
earlier by different offset of MIPI DPHY registers in PMU controllers
(Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to
separate system register controllers (Exynos 5433 case). In both case
also additional 5th PHY (MIPI CSIS 2) has been added.

Controlling Exynos MIPI DPHY is done by handling 2 registers: one for
phy reset and one for enabling it. This patch moves definitions of those
2 registers to speparate exynos_mipi_phy_desc structure, which can be
defined separately for each PHY for each supported hardware variant.
This code rewrite is needed to add support for newer Exynos SoCs, which
have MIPI PHY related registers at different offsets or even different
register regions.

Northstar is a family of SoCs used in home routers. They have USB 2.0
and 3.0 controllers with PHYs that need to be properly initialized.
This driver provides PHY init support in a generic way and can be bound
with an EHCI controller driver.
There are (just a few) registers being defined in bcma header. It's
because DMU/CRU registers will be also needed in other drivers. We will
need them e.g. in PCIe controller/PHY driver and at some point probably
in clock driver for BCM53573 chipset. By using include/linux/bcma/ we
avoid code duplication.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Here's the big USB Gadget pull request. This time
not as large as usual with only 57 non-merge
commits.
The most important part here is, again, all the work
on dwc3. This time around we're treating all
endpoints (except for control endpoint) exactly the
same. They all have the same amount of TRBs on the
ring, they all treat the ring as an actual ring with
a link TRB pointing to the head, etc.
We're also helping the host side burst (on
SuperSpeed GEN1 or GEN2 at least) for as long as
possible until the endpoint returns NRDY.
Other than this big TRB ring rework on dwc3, we also
have a dwc3-omap DMA initialization fix, some extra
debugfs files to aid in some odd debug sessions and
a complete removal of our FIFO resizing logic.
We have a new quirk for some dwc3 P3 quirk in some
implementations.
The rest is basically non-critical fixes and the
usual cleanups.

The phy-am335x driver selects 'USB_COMMON', but all other drivers
use 'depends on' for that symbol, and it depends on USB || USB_GADGET
itself, which causes a Kconfig warning:
warning: (AM335X_PHY_USB) selects USB_COMMON which has unmet direct dependencies (USB_SUPPORT && (USB || USB_GADGET))
As suggested by Felipe Balbi, this turns the logic around, and makes
'USB_COMMON' selected by everything else that needs it, so we can
remove the dependencies.

Most newer Rockchip SoCs provide the possibility to use a usb-phy
as passthrough for the debug uart (uart2), making it possible to
for example get console output without needing to open the device.
This patch adds an early_initcall to enable this functionality
conditionally via the commandline and also disables the corresponding
usb controller in the devicetree.
Currently only data for the rk3288 is provided, but at least the
rk3188 and arm64 rk3368 also provide this functionality and will be
enabled later.
On a spliced usb cable the signals are tx on white wire(D+) and
rx on green wire(D-).
The one caveat is that currently the reconfiguration of the phy
happens as early_initcall, as the code depends on the unflattened
devicetree being available. Everything is fine if only a regular
console is active as the console-replay will happen after the
reconfiguation. But with earlycon active output up to smp-init
currently will get lost.
The phy is an optional property for the connected dwc2 controller,
so we still provide the phy device but fail all phy-ops with -EBUSY
to make sure the dwc2 does not try to transmit anything on the
repurposed phy.

If we reload phy-twl4030-usb, we get a warning about unbalanced
pm_runtime_enable. Let's fix the issue and also fix idling of the
device on unload before we attempt to shut it down.
If we don't properly idle the PHY before shutting it down on removal,
the twl4030 ends up consuming about 62mW of extra power compared to
running idle with the module loaded.

A ton of improvements to dwc2 have been made. The
driver should be a lot more stable on v4.5 then ever
before.
Our good old dwc3 got a few cleanups and misc fixes
and also added support to Xilinx's integration of
this IP.
Yoshihiro Shimoda gives us support for a new USB3
peripheral controller from Renesas.
Other than these, the usual misc fixes all over the
place.

Deprecate using phy-omap-control driver to power on/off the PHY,
and use *syscon* framework to do the same. This handles
powering on/off the PHY for the USB2 PHYs used in various TI SoCs.

No functional change. Previously omap_control_phy_power() was used to power
off the PHY during probe. But once phy-omap-usb2 driver is adapted to
use syscon, omap_control_phy_power() cannot be used. Hence used
omap_usb_power_off to power off the PHY.
