8eaeb93933 mfd: Convert twl6040 to i2c driver, and separate it from twl core
Complete the separation of the twl6040 from the twl core since
it is a separate chip, not part of the twl6030 PMIC.

Make the needed Kconfig changes for the depending drivers at the
same time to avoid breaking the kernel build (vibra, ASoC components).

46a0a5402f ARM: OMAP: boards: Fix OMAP_GPIO_IRQ usage with gpio_to_irq()
The following commits change gpio-omap to use dynamic
IRQ allocation:

25db711 gpio/omap: Fix IRQ handling for SPARSE_IRQ
384ebe1 gpio/omap: Add DT support to GPIO driver

With dynamic allocation of IRQ the usage of OMAP_GPIO_IRQ
is no longer valid. We must be using gpio_to_irq() instead.

Merge tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFD changes from Samuel Ortiz:
 - 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and
   TI's TPS65090 and TPS65217.
 - New variants support (8420, 8520 ab9540), cleanups and bug fixes for
   the abx500 and db8500 ST-E chipsets.
 - Some minor fixes and update for the wm8994 from Mark.

1bfecd9358 ARM: board specific updates
These changes are all specific to one board only. We're trying to keep
 the number of board files low, but generally board level updates are
 ok on platforms that are working on moving towards DT based probing,
 which will eventually lead to removing them.
 
 The board-ams-delta.c board file gets a conflict between the removal of
 ams_delta_config and the addition of a lot of other data. The Kconfig
 file has two changes in the same line, and in exynos, the power domain
 cleanup conflicts with the addition of the image sensor device.

650d6e25cd This has been a very active release for ASoC, as well as the usual raft
of bugfixes and driver updates there's quite a few framework enhancements.
 Most are either small or are laying the groundwork for user visible
 features (especially dynamic PCM), the most directly visible change is
 the dmaengine library.  There's also a bunch of regmap API enhancements
 pulled into the tree so that either the framework or drivers can take
 advantage of the new features.
 
 Changes include:
 
 - Support for widgets not associated with a CODEC, an important part of
   the dynamic PCM framework.
 
 - A library factoring out the common code shared by dmaengine based DMA
   drivers contributed by Lars-Peter Clausen.  This will save a lot of
   code and make it much easier to deploy enhancements to dmaengine.
 
 - Support for binary controls, used for providing runtime configuration
   of algorithm coefficients.
 
 - A new DAPM widget type for regulator supplies allowing drivers for
   devices that can power down unused supplies while active to do without
   any per-driver code.
 
 - DAPM widgets for DAIs, initially giving a speed boost for playback
   startup and shutdown and also the basis for CODEC<->CODEC DAI link
   support.
 
 - Support for specifying the number of significant bits on audio
   interfaces, useful for allowing applications to know how much effort to
   put into generating data for a larger sample format.
 
 - Conversion of the FSI driver used on some SH processors to DMAEngine.
 
 - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200.

d1589f0912 ARM: OMAP2+: Mark omap_hsmmc_init and omap_mux related functions as __init
Now that omap hsmmc init is split into two functions, it's safe
to mark omap_hsmmc_init and omap_mux related functions to __init.

This basically reverts the following fixes for the case where
TWL was compiled as a module:

a98f77b (ARM: omap: fix section mismatch warning for sdp3430_twl_gpio_setup())
8930b4e (ARM: omap: fix section mismatch warnings in mux.c caused by hsmmc.c)

Additionally it fixes up the remaining section warnings for
all callers of omap_mux functions.

3b972bf06c ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pins
Otherwise omap_device_build() and omap_mux related functions
can't be marked as __init when twl is build as a module.

If a board is using GPIO pins or regulators configured by an
external chip, such as TWL PMIC on I2C bus, the board must
mark those MMC controllers as deferred. Additionally both
omap_hsmmc_init() and omap_hsmmc_late_init() must be called
by the board.

For MMC controllers using internal GPIO pins for card
detect and regulators the slots don't need to be marked
deferred. In this case calling omap_hsmmc_init() is sufficient.

Only mark the MMC slots using gpio_cd or gpio_wd as deferred
as noted by Igor Grinberg <grinberg@compulab.co.il>.

Note that this patch does not change the behaviour for
board-4430sdp.c board-omap4panda.c. These boards wrongly
rely on the omap_hsmmc.c init function callback to configure
the PMIC GPIO interrupt lines on external chip. If the PMIC
interrupt lines are not configured during init, they will
fail.

70d669de73 ARM: omap: resolve nebulous 'Error setting wl12xx data'
It's useful to print the error code when a called function fails so a
diagnosis of why it failed is possible.  In this case, it fails because
we try to register some data for the wl12xx driver, but as the driver
is not configured, a stub function is used which simply returns -ENOSYS.

Let's do the simple thing for -rc and print the error code.

Also, the return code from platform_register_device() at each of these
sites was not being checked.  Add some checking, and again print the
error code.

This should be fixed properly for the next merge window so we don't
issue error messages merely because a driver is not configured.

c49d005b6c OMAPDSS: HDMI: PHY burnout fix
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.

This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.

The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.

The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

7496ba309f ARM: OMAP2+: UART: Add default mux for all uarts.
Padconf wakeup is used to wakeup uart after uart fclks/iclks are gated.
Rx-Pad wakeup was done by writing to rx-pad offset value populated in
serial.c idle_init. Remove the direct reading and writing into rx pad.
Remove the padconf field part of omap_uart_state struct and pad offsets
populated.

Now with mux framework support we can use mux_utilities
along with hmwod framework to handle io-pad configuration and enable rx-pad
wake-up mechanism.

To avoid breaking any board support add default mux data for all uart's
if mux info is not passed from board file.
With the default pads populated in serial.c wakeup capability for
rx pads is set, this can be used to enable uart_rx io-pad wakeup from
hwmod framework. The pad values in 3430sdp/4430sdp/omap4panda board file
are same as the default pad values populated in serial.c. Remove pad values
from 3430sdp/4430sdp/omap4panda board file and use the default pads
from serial.c file.

e74984e46e omap: Set separate timer init functions to avoid cpu_is_omap tests
This is needed for the following patches so we can initialize the
rest of the hardware timers later on.

As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
rest of the hardware timers to happen with an arch_initcall.
