b0f3ab20e7 mfd: syscon: atmel-smc: Add helper to retrieve register layout
For HSMC controller, the register layout depends on the device i.e. the
offset of setup, pulse, cycle, mode and timings registers is not the
same. An helper is added to provide the correct register layout.

SMC regs manipulation")

Pull USB updates from Greg KH:
 "Here is the big USB patchset for 4.12-rc1.

  Lots of good stuff here, after many many many attempts, the kernel
  finally has a working typeC interface, many thanks to Heikki and
  Guenter and others who have taken the time to get this merged. It
  wasn't an easy path for them at all.

  There's also a staging driver that uses this new api, which is why
  it's coming in through this tree.

  Along with that, there's the usual huge number of changes for gadget
  drivers, xhci, and other stuff. Johan also finally refactored pretty
  much every driver that was looking at USB endpoints to do it in a
  common way, which will help prevent any "badly-formed" devices from
  causing problems in drivers. That too wasn't a simple task.

  All of these have been in linux-next for a while with no reported
  issues"

SoC Low Power Audio Subsystem.  This is a minimal driver which prepares
resources for IP blocks like I2S, audio DMA and UART and exposes
a regmap for the Top block registers.  Also system power ops are added
to ensure the Audio Subsystem is operational after system suspend/resume
cycle.

This patch adds support for MIPI DPHYs found in Exynos5420-compatible
(5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from
earlier by different offset of MIPI DPHY registers in PMU controllers
(Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to
separate system register controllers (Exynos 5433 case). In both case
also additional 5th PHY (MIPI CSIS 2) has been added.

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.
