16fa3dc75c mfd: omap-usb-tll: HOST TLL platform driver
The platform driver for the TLL component of the OMAP USB host controller
is implemented. Depending on the TLL hardware revision , the TLL channels
are configured. The USB HS core driver uses this driver through exported
APIs from the TLL platform driver.
usb_tll_enable and usb_tll_disble are the exported APIs of the USB TLL
platform driver.

87d687301f mfd: Add syscon driver based on regmap
Add regmap based syscon driver.
This is usually used for access misc bits in registers which does not belong
to a specific module, for example, IMX IOMUXC GPR and ANATOP.
With this driver, client can use generic regmap API to access registers
which are registered into syscon.

a91d2f8d6e mfd: Add MAX8907 core driver
The MAX8907 is an I2C-based power-management IC containing voltage
regulators, a reset controller, a real-time clock, and a touch-screen
controller.

The original driver was written by:
* Gyungoh Yoo <jack.yoo@maxim-ic.com>

Various fixes and enhancements by:
* Jin Park <jinyoungp@nvidia.com>
* Tom Cherry <tcherry@nvidia.com>
* Prashant Gaikwad <pgaikwad@nvidia.com>
* Dan Willemsen <dwillemsen@nvidia.com>
* Laxman Dewangan <ldewangan@nvidia.com>

During upstreaming, I (swarren):
* Converted to regmap.
* Converted to regmap-irq.
* Allowed probing from device tree.
* Renamed from max8907c->max8907, since the driver covers at least the
  C and B revisions.
* General cleanup.

8f057d7bca gpu/mfd/usb: Fix USB randconfig problems
Fix config warning:

warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)

and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!

by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This exposes:

which is due to drivers/usb/Kconfig:
config USB_ARCH_HAS_OHCI
	...
	default y if ARCH_PNX4008 && I2C

Fix by dropping I2C from the above dependency; logic is that this is not a
platform dependency but a configuration dependency: the _architecture_ still
supports USB even is I2C is not selected.

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

  it is ready for inclusion in your tree."

 "Very much Ack on the new subsystem.  It uses the interface
  declarations as the previously separate pwm drivers, so nothing
  changes for now in the drivers using it, although it enables us to
  change those more easily in the future if we want to.

  This work is also one of the missing pieces that are required to

eac7a92fd0 pwm: Conflict with legacy PWM API
In order to avoid duplicate symbols with legacy PWM API implementations,
the new PWM framework needs to conflict with any of the existing legacy
implementations. This is done in two ways: for implementations provided
by drivers, a conflict is added to the driver to ensure it will have to
be ported to the PWM subsystem before it can coexist with other PWM
providers. For architecture-specific code, the conflict is added to the
PWM symbol to avoid confusion when a previously picked platform or
machine can no longer be selected because of the PWM subsystem being
included.

b41511f713 mfd: Add irq domain support for max8997 interrupts
Add irq domain support for max8997 interrupts. The reverse mapping method
used is linear mapping since the sub-drivers of max8997 such as regulator
and charger drivers can use the max8997 irq_domain to get the linux irq
number for max8997 interrupts. All uses of irq_base in platform data and
max8997 driver private data are removed.

c94bb233a9 mfd: Make MFD core code Device Tree and IRQ domain aware
During Device Tree enablement of the ab8500 and db8500-prcmu drivers,
a decision was made to omit registration through the MFD API and use
Device Tree directly. However, because MFD devices have a different
address space and the ab8500 and db8500 both use I2C to communicate,
this causes issues with address translation during execution of
of_platform_populate(). So the solution is to make the MFD core aware
of Device Tree and have it assign the correct node pointers instead.

To make this work the MFD core also needs to be awere of IRQ domains,
as Device Tree insists on IRQ domain compatibility. So, instead of
providing an irq-base via platform code, in the DT case we simply
look up the IRQ domain and map to the correct virtual IRQ.

As the AB8500 is an IRQ controller in its own right, here we provide
the AB8500 driver with IRQ domain support. This is required if we wish
to reference any of its IRQs from a platform's Device Tree.

Problem:
When CONFIG_AB8500_CORE is set, building ab8500-core.c and
!(CONFIG_UX500_SOC_DB8500 | CONFIG_MFD_DB8500_PRCMU), both db8500-prcmu.h

prcmu_abb_read()
prcmu_abb_write()
prcmu_config_clkout()
prcmu_ac_wake_req()
prcmu_ac_sleep_req()

Solution:
Depend on MFD_DB8500_PRCMU, which in turn depends on UX500_SOC_DB8500.

 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

ac1806572d regulator updates for 3.5
The major thing here is the addition of some helpers to factor code out
 of drivers, making a fair proportion of regulators much more just data
 rather than code which is nice.
 
 - Helpers in the core for regulators using regmap, providing generic
   implementations of the enable and voltage selection operations which
   just need data to describe them in the drivers.
 - Split out voltage mapping and voltage setting, allowing many more
   drivers to take advantage of the infrastructure for selectors.
 - Loads and loads of cleanups from Axel Lin once again, including many
   changes to take advantage of the above new framework features
 - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913,
   TI TWL6035 and TI TWL6037.
 
 Some of the registration changes to support the core refactoring caused
 so many conflicts that eventually topic branches were abandoned for this
 release.

Merge tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "The major thing here is the addition of some helpers to factor code
  out of drivers, making a fair proportion of regulators much more just
  data rather than code which is nice.

  - Helpers in the core for regulators using regmap, providing generic
    implementations of the enable and voltage selection operations which
    just need data to describe them in the drivers.
  - Split out voltage mapping and voltage setting, allowing many more
    drivers to take advantage of the infrastructure for selectors.
  - Loads and loads of cleanups from Axel Lin once again, including many
    changes to take advantage of the above new framework features
  - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI
    TPS65913, TI TWL6035 and TI TWL6037.

  Some of the registration changes to support the core refactoring
  caused so many conflicts that eventually topic branches were abandoned
  for this release."

cd99758ba3 mfd: Convert wm831x to irq_domain
The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.

4af8be67fd regmap: Convert regmap_irq to use irq_domain
This gets us up to date with the recommended current kernel infrastructure
and should transparently give us device tree interrupt bindings for any
devices using the framework. If an explicit IRQ mapping is passed in then
a legacy interrupt range is created, otherwise a simple linear mapping is
used. Previously a mapping was mandatory so existing drivers should not
be affected.

A function regmap_irq_get_virq() is provided to allow drivers to map
individual IRQs which should be used in preference to the existing
regmap_irq_chip_get_base() which is only valid if a legacy IRQ range is
provided.

   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again

280ad7fda5 mfd: twl-core: Add IRQ_DOMAIN dependency
TWL4030 depends on IRQ_DOMAIN support, so this patch selects it in Kconfig.
It used to be that CONFIG_IRQ_DOMAIN must only be selected by the architecture,
but recent cleanups have fixed it so that it is safe to select from anywhere.

a3364409c4 MFD: ucb1x00: convert to use genirq
Convert the ucb1x00 driver to use genirq's interrupt services, rather
than its own private implementation.  This allows a wider range of
drivers to use the GPIO interrupts (such as the gpio_keys driver)
without being aware of the UCB1x00's private IRQ system.

This prevents the UCB1x00 core driver from being built as a module,
so adjust the configuration to add that restriction.

6252547b8a ARM: omap: fix broken twl-core dependencies and ifdefs
In commit aeb5032b3f, a dependency on IRQ_DOMAIN was added, which causes
regressions on previously working setups: a previously working non-DT
kernel configuration now loses its PMIC support.  The lack of PMIC
support in turn causes the loss of other functionality the kernel had.

This dependency was added because the driver now registers its
interrupts with the IRQ domain code, presumably to prevent a build error.

The result is that OMAP3 oopses in the vp.c code (fixed by a previous
commit) due to the lack of PMIC support.

However, even with IRQ_DOMAIN enabled, the driver oopses:

Unable to handle kernel NULL pointer dereference at virtual address 00000000

This happens because we try to register an IRQ domain with a NULL ops
structure, and the first thing irq_domain_add() does is try to
dereference this ops structure.

So, fix the problem by getting rid of the incorrect OF_IRQ ifdef and
wrapping the IRQ domain bits of the driver with an IRQ_DOMAIN ifdef
instead.

want to expose a generically named function globally. Move all
required data structures to a shared ab5500-core.h file.

3d5e2cabf1 mfd: ab5500 chip register access
The analog baseband chip ab5500 is a multi functional chip
containing regulators, charging, gpio, USB and accessory detect.
It also contain various multimedia functionalities like digital
encoder and audio codec.
The core driver added with this patch provides register access via
i2c via PRCMU. Event handling implemented as irq_chip will come in
future patches since it depends on PRCMU functionality not yet
implemented.

1f5a371c07 mfd: Add Intel MSIC driver
Add support for Intel MSIC chip found on Intel Medfield platforms. This
chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The
driver creates platform device for each subdevice.

We also provide an MSIC register access API which should replace the more
generic SCU IPC interface currently used. Existing drivers can choose
whether they convert to this new API or stick with the SCU IPC interface.

8a0a8e8e42 mfd: remove CONFIG_MFD_SUPPORT
We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.

Factor out the register read/write code to use the register map API.  We

not affected by the key.

f19b2823f8 mfd: twl6040: Add initial support
TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.

TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.

This driver is based on TWL4030 and WM8350 MFD drivers.
