d65ff52eb8 phy: ti-pipe3: introduce local struct device* in probe
No functional change. Introduce local struct device pointer in
probe and replace using &pdev->dev/phy->dev with the local
device pointer. This is in preparation to split ti_pipe3_probe
and add separate functions for getting mem resource, getting
sysctrl and getting clocks.

After commit 739ae3452d ("phy: berlin-usb: Set drvdata for phy and
use it"), we get the address of priv by phy_get_drvdata(), so there's
no need to set device's driver_data any more. This patch removes the
call of platform_set_drvdata().

b74fe7c761 phy: rockchip-usb: expose the phy-internal PLLs
The USB phys on Rockchip SoCs contain their own internal PLLs to create
the 480MHz needed. Additionally this PLL output is also fed back into the
core clock-controller as possible source for clocks like the GPU or others.

Until now this was modelled incorrectly with a "virtual" factor clock in
the clock controller. The one big caveat is that if we turn off the usb phy
via the siddq signal, all analog components get turned off, including the
PLLs. It is therefore possible that a source clock gets disabled without
the clock driver ever knowing, possibly making the system hang.

Therefore register the phy-plls as real clocks that the clock driver can
then reference again normally, making the clock hirarchy finally reflect
the actual hardware.

The phy-ops get converted to simply turning that new clock on and off
which in turn controls the siddq signal of the phy.

Through this the driver gains handling for platform-specific data, to
handle the phy->clock name association.

f3b5a8d9b5 phy: rcar-gen3-usb2: Add R-Car Gen3 USB2 PHY driver
This patch adds support for R-Car generation 3 USB2 PHY driver.
This SoC has 3 EHCI/OHCI channels, and the channel 0 is shared
with the HSUSB (USB2.0 peripheral) device. And each channel has
independent registers about the PHYs.

So, the purpose of this driver is:
 1) initializes some registers of SoC specific to use the
    {ehci,ohci}-platform driver.

 2) detects id pin to select host or peripheral on the channel 0.

For now, this driver only supports 1) above.

8055555fc4 usb: musb: core: Fix handling of the phy notifications
We currently can't unload omap2430 MUSB platform glue driver module and
this cause issues for fixing the MUSB code further. The reason we can't
remove omap2430 is because it uses the PHY functions and also exports the
omap_musb_mailbox function that some PHY drivers are using.

Let's fix the issue by exporting a more generic musb_mailbox function
from the MUSB core and allow platform glue layers to register phy_callback
function as needed.

And now we can now also get rid of the include/linux/musb-omap.h.

8456799561 locking/atomics, cmpxchg: Privatize the inclusion of asm/cmpxchg.h
After commit:

  654672d4ba ("locking/atomics: Add _{acquire|release|relaxed}() variants of some atomic operations")

Architectures may only provide {cmp,}xchg_relaxed definitions in
asm/cmpxchg.h. Other variants, such as {cmp,}xchg, may be built in
linux/atomic.h, which means simply including asm/cmpxchg.h may not get
the definitions of all the{cmp,}xchg variants.

Therefore, we should privatize the inclusions of asm/cmpxchg.h to
keep it only included in arch/* and replace the inclusions outside
with linux/atomic.h

8d2faea672 This is the bulk of GPIO changes for the v4.3 kernel cycle:
Core changes:
 
 - Root out the wrapper devm_gpiod_get() and gpiod_get() etc
   versions of the descriptor calls that did not use the flags
   argument on the end. This was around for too long and eventually
   Uwe Kleine-König took the time to clean it out and the last
   users are removed along with the macros in this tag. In several
   cases the use of flags simplifies the code. For this reason we
   have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY
   up until we hammer in the nail with removing the macros.
 
 - Add a fat document describing how much ready-made GPIO stuff
   we have i the kernel to discourage people from reinventing
   a square wheel in userspace, as so often happens.
 
 - Create a separate lockdep class for each instance of a GPIO
   IRQ chip instead of using one class for all chips, as the current
   code will not work with systems with several GPIO chips doing
   lockdep debugging.
 
 - Protect against driver unloading also when a GPIO line is only
   used as IRQ for the GPIOLIB_IRQCHIP helpers.
 
 - If the GPIO chip has no designated owner, assign the parent
   device driver owner as owner.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx and Jiang Liu wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 - Rob Herring killed off the set_irq_flags() for all GPIO
   drivers. This was an ARM specific function that is replaced
   with the generic irq_modify_status() where special flags
   are actually needed.
 
 - When an OF node has a pin range for its GPIOs, return
   -EPROBE_DEFER if the pin controller isn't available.
   Pretty logical, yet needed to be fixed.
 
 - If a driver using GPIOLIB_IRQCHIP has its own
   irq_*_resources call back, then call these instead of the
   defaults provided by the GPIOLIB.
 
 - Fix an undocumented ABI hole: named GPIOs were not
   properly documented.
 
 Driver improvements:
 
 - Add get_direction() support to the generic GPIO driver, it's
   strange that we didn't have that before.
 
 - Make it possible to have input-only GPIO chips using the
   generic GPIO driver.
 
 - Clean out platform data support from the Emma Mobile (EM)
   driver
 
 - Finegrained runtime PM support for the RCAR driver.
 
 - Support r8a7795 (R-car H3) in the RCAR driver.
 
 - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
 
 - Some consolidation and new support in the MPC8xxx driver,
   we now support MPC5125.
 
 - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
   spinlocks making it work better with the realime patches.
 
 - Interrupt support for the EXTRAXFS GPIO driver.
 
 - Make the ETRAXFS GPIO driver support also ARTPEC-3.
 
 - Interrupt and wakeup support for the BRCMSTB driver, also for
   wakeup from S5 cold boot.
 
 - Mask MXC IRQs during suspend.
 
 - Improve OMAP2 GPIO set_debounce() to work according to spec.
 
 - The VF610 driver handles IRQs properly.
 
 New drivers:
 
 - ZTE ZX GPIO driver.

Merge tag 'gpio-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.3 kernel cycle.

  There is quite a lot going on in the GPIO subsystem this merge window,

Introduce a new DT parameter 'syscon-pllreset' to provide the syscon

i.e. SATA DPLL refclk will not be disabled and we prevent SoC low

2846469631 phy-sun4i-usb: Swap check for disconnect threshold
Before this commit the code for determining the disconnect threshold was
checking for "allwinner,sun4i-a10-usb-phy" or "allwinner,sun6i-a31-usb-phy"
assuming that those where the exception and then newer SoCs would use a
disconnect threshold of 2 like sun7i does. But it turns out that newer
SoCs use a disconnect threshold of 3 and sun5i and sun7i are the
exceptions, so check for those instead.

Here are the settings from the various Allwinner SDK sources:
 sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
 sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
 sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun8i-h3:  USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);

0a0830feb2 phy: ti-pipe3: fix suspend
Relying on PM-ops for shutting down PHY clocks was a
bad idea since the users (e.g. PCIe/SATA) might not
have been suspended by then.

The main culprit for not shutting down the clocks was
the stray pm_runtime_get() call in probe.

Fix the whole thing in the right way by getting rid
of that pm_runtime_get() call from probe and
removing all PM-ops. It is the sole responsibility
of the PHY user to properly turn OFF and de-initialize
the PHY as part of its suspend routine.

As PHY core serializes init/exit we don't need
to use a spinlock in this driver. So get rid of it.

56301df6bc phy: twl4030-usb: make runtime pm more reliable.
A construct like:

        if (pm_runtime_suspended(twl->dev))
               pm_runtime_get_sync(twl->dev);

is against the spirit of the runtime_pm interface as it
makes the internal refcounting useless.

In this case it is also racy, particularly as 'put_autosuspend'
is used to drop a reference.
When that happens a timer is started and the device is
runtime-suspended after the timeout.
If the above code runs in this window, the device will not be
found to be suspended so no pm_runtime reference is taken.
When the timer expires the device will be suspended, which is
against the intention of the code.

So be more direct is taking and dropping references.
If twl->linkstat is VBUS_VALID or ID_GROUND, then hold a
pm_runtime reference, otherwise don't.
Define "cable_present()" to test for this condition.

1c14905ef9 phy: add driver for TI TUSB1210 ULPI PHY
TUSB1210 ULPI PHY has vendor specific register for eye
diagram tuning. On some platforms the system firmware has
set optimized value to it. In order to not loose the
optimized value, the driver stores it during probe and
restores it every time the PHY is powered back on.

7f7a4d306f phy: fix Kconfig dependencies
DM816x PHY uses usb_phy_* methods and because
of that, it must select USB_PHY, however, because
the drivers in question (DM816x, TWL4030 and
OMAP_USB2) sit outside of drivers/usb/ directory,
meaning they can be built even if USB_SUPPORT=n.

This patches fixes the dependencies by adding
USB_SUPPORT as a dependency and making all drivers
select USB_PHY (which cannot be selected through
menuconfig).

Note that this fixes some linking breakages when
building with randconfig.

devm_phy_create() stores the pointer to the new PHY at the address
returned by devres_alloc(). The res parameter passed to devm_phy_match()
is therefore the location where the pointer to the PHY is stored, hence
it needs to be dereferenced before comparing to the match data in order

bbd3ce86c7 phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the miphy365 phy driver to access sysconfig register offsets via

This is because the reg property should not be mixing address spaces
like it does currently for miphy365. This change then also aligns us

This patch breaks DT compatibility, but this platform is considered WIP,

e4b3d38088 phy: exynos-video-mipi: Fix regression by adding support for PMU regmap
After the Exynos Power Management Unit (PMU) driver was converted
to the platform device driver in commit 14fc8b93d4
("ARM: EXYNOS: Add platform driver support for Exynos PMU") and
then PMU device nodes added to Exynos4 DTs in commit
7b9613aca4 ("ARM: dts: add PMU syscon node for exynos4")
the mipi video phy driver started failing probing, due to overlapping
memory mapped register region resources.

Now all the Exynos peripheral devices which have registers in the PMU
region are supposed to use the regmap provided by the syscon driver.
So support for regmap is added in this patch, this unfortunately
creates yet another indirection into that supposedly trivial driver.

The additional mutex is required because single register is used by
PHY pairs (they share bit in a register). An improvement here could
be to allow a PHY instance be created with a driver custom mutex,
which would then be common for each PHY pair. This would eliminate
one of 3 mutexes which need to be taken in the phy_power_on/
phy_power_off code path. However, I tried to keep this bug fix patch
possibly simple.

This change is needed to make MIPI DSI displays and MIPI CSI-2
camera sensors working again on Exynos4 boards.

5402d927ae phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the phy driver to not use the reg property to access the sysconfig
register offsets.

This is because other phy's (miphy28, miphy365) have a combination of
memory mapped registers and sysconfig control regs, and we shouldn't
be mixing address spaces in the reg property. In addition we would
ideally like the sysconfig offsets to be passed via DT in a uniform way.

This new method will also allow us to support devices which have sysconfig
registers in different banks more easily and it is also analagous to how
keystone and bcm7745 platforms pass there syscon offsets in DT.

This breaks DT compatibility, but this platform is considered WIP, and
is only used by a few developers who are upstreaming support for it.

7f33912d29 phy: ti-pipe3: Fix SATA across suspend/resume
Failed test case: Boot without SATA drive connected. Suspend/resume
the board and then connect SATA drive. It fails to enumerate.

Due to Errata i783 "SATA Lockup After SATA DPLL Unlock/Relock"
we can't allow SATA DPLL to be in the unlocked state.
The SATA refclk (sata_ref_clk) is the source of the SATA_DPLL.
This clock is being controlled only by the AHCI SATA driver and is
shut off during system suspend (if the SATA drive was not already attached)
causing the SATA DPLL to be unlocked and so causing errata i783.

To prevent sata_ref_clk from being disabled, we add the control of
this clock to the SATA PHY driver and prevent it from being disabled.

This also fixes the issue of SATA not working on OMAP5/DRA7 when
AHCI platform driver is built as a module.

NOTE: Device tree changes also required for OMAP5 & DRA7.

6e7384320f phy: ti-pipe3: Disable clocks on system suspend
On system suspend, the runtime_suspend() driver hook doesn't get
called for USB phy and so the clocks are not disabled in the driver.
This causes the L3INIT_960M_GFCLK and L3INIT_480M_GFCLK to remain
active on the DRA7 platform while in system suspend.

In case of pcie-phy, the runtime_suspend hook gets called after
the suspend hook so we introduce a flag phy->enabled to keep
track if our clocks are enabled or not to prevent multiple
enable/disables.

Add suspend/resume hooks to the driver.
Move enabling/disabling clock code into helper functions.

937127fe13 phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.
Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
update the phy driver to not use the reg property to access the sysconfig
register offsets.

This is because other phy's (miphy28, miphy365) have a combination of
memory mapped registers and sysconfig control regs, and we shouldn't
be mixing address spaces in the reg property. In addition we would
ideally like the sysconfig offsets to be passed via DT in a uniform way.

This new method will also allow us to support devices which have sysconfig
registers in different banks more easily and it is also analagous to how
keystone and bcm7745 platforms pass there syscon offsets in DT.

This breaks DT compatibility, but this platform is considered WIP, and
is only used by a few developers who are upstreaming support for it.

0bc09f9cdc phy: phy-ti-pipe3: fix inconsistent enumeration of PCIe gen2 cards
Prior to DRA74x silicon rev 1.1, pcie_pcs register bits 8-15 and bits 16-23
were used to configure RC delay count for phy1 and phy2 respectively.
phyid was used as index to distinguish the phys and to configure the delay
values appropriately.

As of DRA74x silicon rev 1.1, pcie_pcs register definition has changed.
Bits 16-23 are used to configure delay values for *both* phy1 and phy2.

Hence phyid is no longer required.

So, drop id field from ti_pipe3 structure and its subsequent references
for configuring pcie_pcs register.

Also, pcie_pcs register now needs to be configured with delay value of 0x96
at bit positions 16-23. See register description of CTRL_CORE_PCIE_PCS in
ARM572x TRM, SPRUHZ6, October 2014, section 18.5.2.2, table 18-1804.

This is needed to ensure Gen2 cards are enumerated consistently.

DRA72x silicon behaves same way as DRA74x rev 1.1 as far as this functionality
is considered.

Test results on DRA74x and DRA72x EVMs:

Before patch
------------
DRA74x ES 1.0: Gen1 cards work, Gen2 cards do not work (expected result due to
silicon errata)
DRA74x ES 1.1: Gen1 cards work, Gen2 cards do not work sometimes due to incorrect
programming of register

DRA72x: Gen1 cards work, Gen2 cards do not work sometimes due to incorrect
programming of register

After patch
-----------
DRA74x ES 1.0: Gen1 cards work, Gen2 cards do not work (expected result due to
silicon errata)
DRA74x ES 1.1: Gen1 cards work, Gen2 cards work consistently.

DRA72x: Gen1 and Gen2 cards enumerate consistently.

c0f486fde3 More ACPI and power management updates for 3.19-rc1
- Fix a regression in leds-gpio introduced by a recent commit that
    inadvertently changed the name of one of the properties used by
    the driver (Fabio Estevam).
 
  - Fix a regression in the ACPI backlight driver introduced by a
    recent fix that missed one special case that had to be taken
    into account (Aaron Lu).
 
  - Drop the level of some new kernel messages from the ACPI core
    introduced by a recent commit to KERN_DEBUG which they should
    have used from the start and drop some other unuseful KERN_ERR
    messages printed by ACPI (Rafael J Wysocki).
 
  - Revert an incorrect commit modifying the cpupower tool
    (Prarit Bhargava).
 
  - Fix two regressions introduced by recent commits in the OPP
    library and clean up some existing minor issues in that code
    (Viresh Kumar).
 
  - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout
    the tree (or drop it where that can be done) in order to make
    it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki,
    Ulf Hansson, Ludovic Desroches).  There will be one more
    "CONFIG_PM_RUNTIME removal" batch after this one, because some
    new uses of it have been introduced during the current merge
    window, but that should be sufficient to finally get rid of it.
 
  - Make the ACPI EC driver more robust against race conditions
    related to GPE handler installation failures (Lv Zheng).
 
  - Prevent the ACPI device PM core code from attempting to
    disable GPEs that it has not enabled which confuses ACPICA
    and makes it report errors unnecessarily (Rafael J Wysocki).
 
  - Add a "force" command line switch to the intel_pstate driver
    to make it possible to override the blacklisting of some
    systems in that driver if needed (Ethan Zhao).
 
  - Improve intel_pstate code documentation and add a MAINTAINERS
    entry for it (Kristen Carlson Accardi).
 
  - Make the ACPI fan driver create cooling device interfaces
    witn names that reflect the IDs of the ACPI device objects
    they are associated with, except for "generic" ACPI fans
    (PNP ID "PNP0C0B").  That's necessary for user space thermal
    management tools to be able to connect the fans with the
    parts of the system they are supposed to be cooling properly.

f20531a9aa phy: omap-usb2: Enable runtime PM of omap-usb2 phy properly
The USB OTG port does not work since v3.16 on omap platform.
This is a regression introduced by the commit
eb82a3d846 (phy: omap-usb2: Balance pm_runtime_enable() on probe failure
 and remove).
This because the call to pm_runtime_enable() function is moved after the
call to devm_phy_create() function, which has side effect since later in
the subsequent calls of devm_phy_create() there is a check with
pm_runtime_enabled() to configure few things.

1233f59f74 phy: Renesas R-Car Gen2 PHY driver
This PHY, though formally being a part of Renesas USBHS controller, contains the
UGCTRL2 register that controls multiplexing of the USB ports (Renesas calls them
channels) to the different USB controllers: channel 0 can be connected to either
PCI EHCI/OHCI or USBHS controllers, channel 2 can be connected to PCI EHCI/OHCI
or xHCI controllers.

This is a new driver for this USB PHY currently already supported under drivers/
usb/phy/. The reason for writing the new driver was the requirement that the
multiplexing  of USB channels to the controller be dynamic, depending on what
USB drivers  are loaded,  rather than static as provided by the old driver. The
infrastructure provided by drivers/phy/phy-core.c  seems to fit that purpose
ideally. The new driver only  supports device tree probing  for now.

Commit 249751f223 ("usb: phy: twl4030-usb: poll for ID disconnect")
added twl4030_id_workaround_work() to deal with lost interrupts
after ID pin goes down. Looks like commit f1ddc24c9e ("usb: phy:
twl4030-usb: remove *set_suspend* and *phy_init* ops") changed
things around for the generic phy framework, and delayed work no
longer got called except initially during boot.

The PHY connect and disconnect interrupts for twl4030-usb are not
working after disconnecting a USB-A cable from the board, and the
deeper idle states for omap are blocked as the USB controller
stays busy.

The issue can be solved by calling delayed work from twl4030_usb_irq()
when ID pin is down and the PHY is not asleep like we already do
in twl4030_id_workaround_work().

But as both twl4030_usb_irq() and twl4030_id_workaround_work()
already do pretty much the same thing, let's call twl4030_usb_irq()
from twl4030_id_workaround_work() instead of adding some more
duplicate code. We also must call sysfs_notify() only when we have
an interrupt and not from the delayed work as notified by
Grazvydas Ignotas <notasas@gmail.com>.

Commit 30a70b026b ("usb: musb: fix obex in g_nokia.ko causing kernel
panic") attempted to fix runtime PM handling for PHYs that are on the
I2C bus. Commit 3063a12be2 ("usb: musb: fix PHY power on/off") then
changed things around to enable of PHYs that rely on runtime PM.

These changes however broke idling of the PHY and causes at least
100 mW extra power consumption on omaps, which is a lot with
the idle power consumption being below 10 mW range on many devices.

As calling phy_power_on/off from runtime PM calls in the USB
causes complicated issues with I2C connected PHYs, let's just let
the PHY do it's own runtime PM as needed. This leaves out the
dependency between PHYs and USB controller drivers for runtime
PM.

Let's fix the regression for twl4030-usb by adding minimal runtime
PM support. This allows idling the PHY on disconnect.

Note that we are changing to use standard runtime PM handling
for twl4030_phy_init() as that function just checks the state
and does not initialize the PHY. The PHY won't get initialized
until in twl4030_phy_power_on().

A handful of driver-related changes. We've had a bunch of them going in through
 other branches as well, so it's only a part of what we really have this release.
 
 Larger pieces are:
 
 * Removal of a now unused PWM driver for atmel
   - This includes AVR32 changes that have been appropriately acked.
 * Performance counter support for the arm CCN interconnect
 * OMAP mailbox driver cleanups and consolidation
 * PCI and SATA PHY drivers for SPEAr 13xx platforms
 * Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to
   better model regulators/power.

b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

942a31b521 phy: add a driver for the Berlin SATA PHY
The Berlin SoC has a two SATA ports. Add a PHY driver to handle them.

The mode selection can let us think this PHY can be configured to fit
other purposes. But there are reasons to think the SATA mode will be
the only one usable: the PHY registers are only accessible indirectly
through two registers in the SATA range, the PHY seems to be integrated
and no information tells us the contrary. For these reasons, make the
driver a SATA PHY driver.

59025887fb phy: Add new Exynos5 USB 3.0 PHY driver
Add a new driver for the USB 3.0 PHY on Exynos5 series of SoCs.
The new driver uses the generic PHY framework and will interact
with DWC3 controller present on Exynos5 series of SoCs.

Also, created a new header file in linux/mfd/syscon/ for
Exynos5 SoCs and put the required PMU offset definitions
for the basic available PHYs.

3fc03f3d72 phy: kona2: use 'select GENERIC_PHY' in Kconfig
All other phy drivers use 'select', while this one is
the only one to use 'depends on'. This is not a bug, just
slightly inconsistent, so let's change it to do things the
same way as everyone else.

We may also want to turn GENERIC_PHY into a silent option
that only ever gets turned on if another driver needs it.

9f1d8ed227 phy: omap-usb2: Use generic clock names "wkupclk" and "refclk"
As clocks might be named differently on multiple platforms, use a generic
name in the driver and allow device tree node to specify the platform
specific clock name.

743bb387a1 phy: fix kernel oops in phy_lookup()
The kernel oopses in phy_lookup() due to 'phy->init_data' being NULL if we
register PHYs from a device tree probing driver and then call phy_get() on a
device that has no representation in the device tree (e.g. a PCI device).
Checking the pointer before dereferening it and skipping an interation if
it's NULL prevents this kernel oops.

907aa3aa8d phy: restore OMAP_CONTROL_PHY dependencies
When OMAP_CONTROL_USB was renamed to OMAP_CONTROL_PHY (commit
14da699b), its dependencies were lost in the process. Nothing in the
commit message indicates that this removal was intentional, so I think
it was by accident and the dependencies should be restored.
