Roger Quadros c934b36127 phy: ti-pipe3: i783 workaround for SATA lockup after dpll unlock/relock
SATA_PLL_SOFT_RESET bit of CTRL_CORE_SMA_SW_0 must be toggled
between a SATA DPLL unlock and re-lock to prevent SATA lockup.

Introduce a new DT parameter 'syscon-pllreset' to provide the syscon
regmap access to this register which sits in the control module.

If the register is not provided we fallback to the old behaviour
i.e. SATA DPLL refclk will not be disabled and we prevent SoC low
power states.

The usb0 phy is connected to an OTG controller, and as such needs some special

1) It allows explicit control over the pullups, enable these on phy_init and
disable them on phy_exit.

2) It has bits to signal id and vbus detect to the musb-core, add support for
for monitoring id and vbus detect gpio-s for use in dual role mode, and set
these bits to the correct values for operating in host only mode when no
gpios are specified in the devicetree.

Sylwester Nawrocki 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.

Peter Griffin 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.

Vivek Gautam a5ec598650 phy: exynos-dp-video: Use syscon support to control pmu register
Currently the DP_PHY_ENABLE register is mapped in the driver,
and accessed to control power to the PHY.
With mfd-syscon and regmap interface available at our disposal,
it's wise to use that instead of using a 'reg' property for the
controller and allocating a memory resource for that.

To facilitate this, we have added another compatible string
for Exynso5420 SoC to acquire driver data which contains
different DP-PHY-CONTROL register offset.

Sergei Shtylyov 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.

Linus Torvalds 10c8e05620 ARM: SoC driver changes for 3.17
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.

 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
