Now there are generic phy type constants declared in phy.h, migrate over to
using them rather than defining our own. This change has been done as one
atomic commit to be bisectable.
Note: The values of the defines are the same, so there is no ABI breakage
with this patch.

Add a minimal driver for dm816x USB. This makes USB work on dm816x
without any other changes needed as it can use the existing musb_dsps
glue layer for the USB controller.
Note that this phy is different from dm814x and am335x.

This patchset attempts to standardize the naming of dt-bindings
documents based on the Broadcom vendor prefix of brcm.
Although there are no guidelines currently present for how to name
the dt-bindings document the "vendor,binding.txt" style is in use by

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
syscfg dt property.
This is because the reg property should not be mixing address spaces
like it does currently for miphy365. This change then also aligns us
to how other platforms such as keystone and bcm7445 pass there syscon
offsets via DT.
This patch breaks DT compatibility, but this platform is considered WIP,
and is only used by a few developers who are upstreaming support for it.
This change has been done as a single atomic commit to ensure it is
bisectable.

After the Exynos Power Management Unit (PMU) driver was converted
to the platform device driver in commit 14fc8b93d47323561edf5d482
("ARM: EXYNOS: Add platform driver support for Exynos PMU") and
then PMU device nodes added to Exynos4 DTs in commit
7b9613aca42a5522d269 ("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.

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.

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.

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 ba0d7ed391b7b "ARM: dts: enable ahci sata and sata phy for
exynos5250" added a new binding document for the sata phy device,
and changed the sata controller binding. However, in both cases
significant aspects of the binding remained undocumented.
This attempts to reconstruct the actual binding from the usage.

Kishon writes:
Add new PHY drivers for SATA and USB in exynos, for USB in sunxi,
and a multi-purpose PHY in APM, all adapted to generic PHY framework.
Adapted USB3 PHY driver in OMAP to generic PHY driver and also used
the same driver for SATA in OMAP. It also includes miscellaneous cleanups
and fixes.
