Pull devicetree changes from Grant Likely:
 "Here are the devicetree changes queued up for v4.1.  Nothing really
  exciting here.  Rob has another few commits for big-endian attached
  UARTs, but those will be sent in a separate merge request since they
  haven't been as thoroughly tested as this batch.

  Here are the highlights:

   - lots of unittest cleanup from Frank Rowand

   - bugfixes and updates to the of_graph code

   - tighten up of_get_mac_address() code

   - documentation updates"

phy: miphy365x: Use the generic phy type constants in dt-bindings/phy/phy.h

2015-04-03T12:46:20+00:00

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.

phy: Add driver to support individual USB PHYs on sun9i

2015-04-03T12:46:19+00:00

Unlike previous Allwinner SoCs, there is no central PHY control block
on the A80. Also, OTG support is completely split off into a different
controller.

This adds a new driver to support the regular USB PHYs.

phy: Add a driver for dm816x USB PHY

2015-04-03T12:46:19+00:00

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.

dt-bindings: brcm: rationalize Broadcom documentation naming

2015-03-26T17:14:11+00:00

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
some of the other vendors.

phy: exynos5-usbdrd: Add to support for Exynos5433 SoC

2015-03-25T23:36:10+00:00

This patch adds driver data to support for Exynos5433 SoC.
The Exynos5433 has one USB3.0 Host and USB3.0 DRD(Dual Role Device).
Exynos5433 is simplar to Eyxnos7 but Exynos5433 have
one more USB3.0 Host controller.

phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.

2015-01-30T12:42:05+00:00

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.

phy: exynos-video-mipi: Fix regression by adding support for PMU regmap

2015-01-30T10:36:48+00:00

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.

phy: phy-stih407-usb: Pass sysconfig register offsets via syscfg property.

2015-01-21T09:53:06+00:00

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.
