Modelling the RESET line as a regulator supply wasn't a good idea
as it kind of abuses the regulator framework and also makes adaptation
code more complex.
Instead, manage the RESET gpio line directly in the driver. Update
the device tree binding information.
This also makes us easy to migrate to a dedicated GPIO RESET controller
whenever it becomes available.

This is based on George Cherian's patch which added power & wakeup
support to am335x and does no longer apply since I took some if the code
apart in favor of the multi instance support.
This compiles and I boots and later it detects a device after I plug it in :)
Could somebody please test it so it does what it should?

Since we only enable the PHY clock on init and the PHY init and shutdown
does not occur in atomitc context there is no need to prepare the clock
before it is enabled. Move the clk_prepare() operations to go along
with the enables, allowing the clock to be fully idle when not in use.

Felipe writes:
usb: patches for v3.12 merge window
All patches here have been pending on linux-usb
and sitting in linux-next for a while now.
The biggest things in this tag are:
DWC3 learned proper usage of threaded IRQ
handlers and now we spend very little time
in hardirq context.
MUSB now has proper support for BeagleBone and
Beaglebone Black.
Tegra's USB support also got quite a bit of love
and is learning to use PHY layer and generic DT
attributes.
Other than that, the usual pack of cleanups and
non-critical fixes follow.

Stephen Rothwell reported that this driver does not compile on PowerPC
due to this missing include. One could argue why this driver is enabled
on PowerPC in the first place but it sure isn't wrong to include headers
for used function instead of to rely that they sneak in.

The Tegra30 TRM recommends configuration of certain PHY parameters for
optimal quality. Program the following registers based on device tree
parameters:
- UTMIP_XCVR_HSSLEW: HS slew rate control.
- UTMIP_HSSQUELCH_LEVEL: HS squelch detector level
- UTMIP_HSDISCON_LEVEL: HS disconnect detector level.
These registers exist in Tegra20, but programming them hasn't been
necessary, so these parameters won't be set on Tegra20 to keep the
device trees backward compatible.
Additionally, the UTMIP_XCVR_SETUP parameter can be set from fuses
instead of a software-programmed value, as the optimal value can
vary between invidual boards. The boolean property
nvidia,xcvr-setup-use-fuses can be used to enable this behaviour.

The Tegra30 USB PHY is a bit different than the Tegra20 PHY:
- The EHCI controller supports the HOSTPC register extension, and some
of the fields that the PHY needs to modify (PHCD and PTS) have moved
to the new HOSTPC register.
- Some of the UTMI PLL configuration registers have moved from the USB
register space to the Clock-And-Reset controller space. In Tegra30
the clock driver is responsible for configuring the UTMI PLL.
- The USBMODE register must be explicitly written to enter host mode.
- Certain PHY parameters need to be programmed for optimal signal
quality. Support for this will be added in the next patch.
The new tegra_phy_soc_config structure is added to describe the
differences between the SoCs.

This driver is a redo of my earlier attempt. It uses parts of the
generic PHY driver and uses the new control driver for the register
the phy needs to power on/off the phy. It also enables easy access for
the wakeup register which is not yet implemented.
The difference between the omap attempt is:
- no static holding variable
- one global visible function which exports a struct with callbacks to
access the "control" registers.

The tegra ehci driver has enabled USB vbus regulators directly using
GPIOs and the device tree attribute nvidia,vbus-gpio. This is ugly
and causes error messages on boot when both the regulator driver
and the ehci driver want access to the same GPIO.
After this patch, usb vbus regulators for tegra usb phy devices are specified
with the device tree attribute vbus-supply = <&x> where x is a regulator defined
in the device tree. The old nvidia,vbus-gpio property is no longer supported.

Convert PHY Drivers from menuconfig to menu so that the PHY drivers
can be explicitely selected by the controller drivers.
USB_PHY is no longer a user visible option. It is upto to the PHY
drivers to select it if needed. This patch does so for the existing
PHY drivers that use the USB_PHY library.
Doing so moves the USB_PHY and PHY driver selection problem from the
end user to the PHY and controller driver developer.
e.g.
Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select
a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver
depended on USB_PHY. Making the controller driver depend on USB_PHY
has a negative effect i.e. it becomes invisible to the user till
USB_PHY is enabled. Most end users will not familiar with this.
With this patch, the end user just needs to select the controller driver
needed for his/her platform without worrying about which PHY driver to
select.
Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend
on USB_PHY any more. They can safely select the necessary PHY drivers.

commit 57f6ce072e35770a63be0c5d5e82f90d8da7d665 ("usb: phy:
add a new driver for usb3 phy") added the new Kconfig option
OMAP_USB3, but it had no dependencies whatsoever, and hence
became available across all arch/platforms.
Which presumably caused this to show up in x86 randconfig:
warning: (USB_MUSB_HDRC && OMAP_USB3) selects \
OMAP_CONTROL_USB which has unmet direct \
dependencies (USB_SUPPORT && ARCH_OMAP2PLUS)
Then commit 6992819feb39cb9adac72170555d957d07f869f2 ("usb: phy:
fix Kconfig warning") was added. However, this just deleted the
ARCH_OMAP2PLUS dependency from OMAP_CONTROL_USB, further
compounding the problem by opening up OMAP_CONTROL_USB to
all arch/platforms as well.
Earlier it was suggested[1] that we revert the change of 6992819feb
to restore the dependency, and add a same ARCH_OMAP2PLUS dependency
to the new OMAP_USB3 entry. However that was discouraged on the
grounds of people wanting the extra sanity compile testing on x86,
even though the driver could probably never be used there.
Now we have CONFIG_COMPILE_TEST, so developers who value the ability
to compile drivers on an architecture that it never can be used for
can have that, and people who want dependencies to shield them from
seeing options that aren't relevant to their platform get what they
want too.
Here we restore the dependency but couple it with COMPILE_TEST, in
order to achieve both of the above goals.

Pull ARM SoC specific changes from Arnd Bergmann:
"These changes are all to SoC-specific code, a total of 33 branches on
17 platforms were pulled into this. Like last time, Renesas sh-mobile
is now the platform with the most changes, followed by OMAP and
EXYNOS.
Two new platforms, TI Keystone and Rockchips RK3xxx are added in this
branch, both containing almost no platform specific code at all, since
they are using generic subsystem interfaces for clocks, pinctrl,
interrupts etc. The device drivers are getting merged through the
respective subsystem maintainer trees.
One more SoC (u300) is now multiplatform capable and several others
(shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
towards that goal with this series but need more work.
Also noteworthy is the work on PCI here, which is traditionally part
of the SoC specific code. With the changes done by Thomas Petazzoni,
we can now more easily have PCI host controller drivers as loadable
modules and keep them separate from the platform code in
drivers/pci/host. This has already led to the discovery that three
platforms (exynos, spear and imx) are actually using an identical PCIe
host controller and will be able to share a driver once support for
spear and imx is added."

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/late
From David Brown:
MSM clock updates for 3.11.
Per Stephen Boyd's coverletter:
Resending to collect higher level maintainer acks per Olof's request.
The plan is to push this patchset through MSM to the arm-soc tree.
This patchset moves the existing MSM clock code and affected drivers
to the common clock framework. A prerequisite of moving to the common
clock framework is to use clk_prepare() and clk_enable() so the first
few patches migrate drivers to that call (clk_prepare() is a no-op on
MSM right now). It also removes some custom clock APIs that MSM
provides and finally moves the proc_comm clock code to the common
struct clk.
This patch series will be used as the foundation of the MSM 8660/8960
clock code that I plan to send out after this series.
