ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code
Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c. This
mostly consists of removing the first attempt at device PM latency
handling. This was never really used, has been replaced by the common
dev_pm_qos code, and needs to go away as part of the DT conversion.
Also, the early platform_device creation code has been removed, as it
appears to be unused.

We want to remove plat/cpu.h. To do this, let's first split
it to private soc.h to mach-omap1 and mach-omap2. We have to
keep plat/cpu.h around until the remaining drivers are fixed,
so let's include the local soc.h in plat/cpu.h and for drivers
still including plat/cpu.h.
Once the drivers are fixed not to include plat/cpu.h, we
can remove the file.
This is needed for the ARM common zImage support.

ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xx
Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.) To make it more clear what is
being detected, convert the names from 3517 to AM35xx.
This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517().
In order to avoid cross-tree dependencies with clock-tree changes,
cpu_is_omap3517() is left until the clock changes are merged,
at which point cpu_is_omap3517() will be completely removed.

ARM: OMAP: AM35xx: remove redunant cpu_is checks for AM3505
There are several checks for AM35x devices done using
if (cpu_is_omap3517() || cpu_is_omap3505())
However, since the 3505 is just a 3517 without an SGX, the 3505 check
is redundant because cpu_is_omap3517() will always be true whenever
cpu_is_omap3505() is true. From <plat/cpu.h>:
#define cpu_is_omap3505() (cpu_is_omap3517() && !omap3_has_sgx())
Therefore, remove the redunant 3505 checks. This helps move towards
removal of SoC detection that depends on specific IP detection.

If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems
2.1.1.128 erratum doesn't apply and there is no data corruption,
probably because of different signal timing. The workaround for this

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.

ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a module
On some omaps twl4030_gpio has a callback to try to initialize
the MMC controller. If twl4030_gpio is compiled as a module,
bad things can happen because the callback function starts
calling functions that are supposed to be marked __init:
Kernel panic - not syncing: Attempted to kill the idle task!
twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules
gpiochip_add: registered GPIOs 192 to 209 on device: twl4030
Unable to handle kernel paging request at virtual address b82a4c74
...
Additionally if this does not fail, warnings are produced
about trying to register the MMC multiple times.
Fix this by removing __init from omap_mux_get_by_name,
and add checks if omap2_hsmmc_init() is getting called more
than once.
Note that this will get fixed properly later on by splitting
omap2_hsmmc_init into two functions.

The function sdp3430_twl_gpio_setup() references

This is often because sdp3430_twl_gpio_setup lacks a __init

sdp3430_twl_gpio_setup() is called via platform data from the
gpio-twl4030 module, which can be inserted and removed at runtime.
This makes sdp3430_twl_gpio_setup() callable at runtime, and prevents
it being marked with an __init annotation.
As it calls omap2_hsmmc_init() unconditionally, the only resolution to
this warning is to remove the __init markings from omap2_hsmmc_init()
and its called functions. This addresses the functions in hsmmc.c.

hsmmc23_before_set_reg() can set MMCSDIO2ADPCLKISEL bit, which
enables internal clock for MMC2. Currently this function is also called
by code handling MMC3, and if .internal_clock is set in platform data
(by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2
instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to
be done). This breaks 2nd SD slot on pandora.
Fix this by changing hsmmc23_before_set_reg() to only handle MMC2.
Note that this removes .remux() call for MMC3, but no board currently
needs it and it's also not called for MMC4 and MMC5.

OMAP: omap_device: when building return platform_device instead of omap_device
All of the device init and device driver interaction with omap_device
is done using platform_device pointers. To make this more explicit,
have omap_device return a platform_device pointer instead of an
omap_device pointer.
All current users of the omap_device pointer were only using it to get
at the platform_device pointer or struct device pointer, so fixing all
of the users was trivial.
This also makes it more difficult for device init code to directly
access members of struct omap_device, and allows for easier changing
of omap_device internals.

OMAP: adapt hsmmc to hwmod framework
OMAP2420 platform consists of mmc block as in omap1 and not the
hsmmc block as present in omap2430, omap3, omap4 platforms.
Removing all base address macro defines except keeping one for OMAP2420 and
adapting only hsmmc device registration and driver to hwmod framework.
Changes involves:
1) Remove controller reset in devices.c which is taken care of
by hwmod framework.
2) Using omap-device layer to register device and utilizing data from
hwmod data file for base address, dma channel number, Irq_number,
device attribute.
3) Update the driver to use dev_attr to find whether controller
supports dual volt cards

OMAP: control: move plat-omap/control.h to mach-omap2/control.h
Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap. This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.
In response, move the SCM headers into mach-omap2/.
As part of this, remove the direct SCM access from the OMAP UDC
driver. It was clearly broken. The UDC code needs an indepth review for
use on OMAP2+ chips.

omap4 hsmmc: Register offset handling
In OMAP4, as per new PM programming model, the legacy registers
which were there in OMAP3 are all shifted by 0x100 while new one's
are added from offset 0 to 0x10.
For OMAP4, the register offset appending of 0x100 done in devices.c
currently, is moved to driver file.This change fits in for current
implementation as well as once the driver undergoes hwmod adaptation.

omap_hsmmc: Allow for a shared VccQ
EMMC can have two voltage supplies, Vcc and VccQ
which are implemented in the code as consumer
supplies vmmc and vmmc_aux.
If the regulator that supplies vmmc_aux is shared
with other consumers, then sending it to sleep
will disrupt those consumers. However, the
TWL4030-family regulators may have OFF remapped
to SLEEP, in which case 'regulator_disable()'
will put the regulator to sleep only when all
consumers are disabled - which is the desired
behaviour.
This patch adds a platform data field to allow
that option.

omap: RX51: Remux to pull eMMC lines down when powering off
It has been discovered that, when eMMC is powered off, current
will flow from OMAP eMMC data pull-ups to the eMMC voltage supply.
Configuring pads for OMAP off-mode does not help because eMMC is
powered off independently of OMAP off-mode. Hence the pads are
now re-configured when eMMC is powered on or off.
