Amstrad Delta MODEM device used to be initialized at arch_initcall
before it was once moved to late_initcall by commit f7519d8c82 ("ARM:
OMAP1: ams-delta: register latch dependent devices later"). The purpose
of that change was to postpone initialization of devices which depended
on latch2 pins until latch2 converted to GPIO device was ready.
After recent fixes to GPIO handling, it was possible to moove
registration of most of those device back to where they were before.
The same can be safely done with the MODEM device as initialization
of GPIO pins it depends on was moved to machine_init by preceding
patch.
Move registration of the MODEM device to arch_initcall_sync, not to
arch_initcall, so it is never exposed to potential conflict in
registration order hazard against OMAP serial ports.

Latch2 pins control a number of on-board devices, namely LCD, NAND,
MODEM and CODEC. Those pins used to be initialized with safe values
from init_machine before that operation was:
1) moved to late_initcall in preparation for conversion of latch2 to
GPIO device - see commit f7519d8c82 ("ARM: OMAP1: ams-delta: register
latch dependent devices later"),
2) replaced with non-atomic initialization performed by means of
gpio_request_array() - see commit 937eb4bb00 ("ARM: OMAP1: ams-delta:
convert latches to basic_mmio_gpio"),
3) made completely asynchronous by delegation of GPIO request
operations performed on subsets of pins to respective device drivers in
subsequent commits.
One visible negative result of that disintegration was corrupt keyboard
data reported by serio driver, recently fixed by commit 41f8fee385
("ARM: OMAP1: ams-delta: Hog "keybrd_dataout" GPIO pin").
Moreover, initialization of LATCH2_PIN_MODEM_CODEC still performed with
ams_delta_latch2_write() wrapper from late_init() is now done on not
requested GPIO pin.
Reintroduce atomic initialization of latch2 pins at machine_init to
prevent from random values potentially corrupting NAND data or maybe
even destroing other hardware. Also take care of MODEM/CODEC related
pins so MODEM device probe succeeds even if latch2 GPIO device or
dependent regulator is not ready and CODEC can be reached over the
MODEM even if audio driver doesn't take control over
LATCH2_PIN_MODEM_CODEC.
Once done, remove the no longer needed GPIO based implementation of
ams_delta_latch_write() and its frontend macro.

As we augmented the regulator core to accept a GPIO descriptor instead
of a GPIO number, we can augment the fixed GPIO regulator to look up
and pass that descriptor directly from device tree or board GPIO
descriptor look up tables.
Some boards just auto-enumerate their fixed regulator platform devices
and I have assumed they get names like "fixed-regulator.0" but it's
pretty hard to guess this. I need some testing from board maintainers to
be sure. Other boards are straight forward, using just plain
"fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the
device ID.
It seems the da9055 and da9211 has never got around to actually passing
any enable gpio into its platform data (not the in-tree code anyway) so we
can just decide to simply pass a descriptor instead.
The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named
"*_dummy_supply_device" while it is a very real device backed by a GPIO
line. There is nothing dummy about it at all, so I renamed it with the
infix *_regulator_* as part of this patch set.

Initialization of several Amstrad Delta devices was once moved to
late_initcall by commit f7519d8c82 ("ARM: OMAP1: ams-delta: register
latch dependent devices later"). The purpose of that move was to allow
smooth conversion of Amstrad Delta latches to GPIO.
After successful conversion only ams_delta_serio driver was moved back
to device_initcall by commit 8d09a1bb31 ("input: serio: ams-delta:
toggle keyboard power over GPIO"). Registration of ams-delta-nand and
lcd_ams_delta devices was kept in late_initcall in order to avoid
corrupt data reported by the serio driver on boot. Registration of
cx20442-codec device was kept there for it to be probed after a
regulator on which it depended was ready.
The issue of "keybrd_dataout" GPIO pin not initilized to GPIO_OUT_LOW
before other latch2 pins causing the corruption have been apparently
fixed by commit 5322c19b117a ("ARM: OMAP1: ams-delta: Hog
"keybrd_dataout" GPIO pin"). In turn, the issue of missing regulator
has been fixed by commit 50c678772a ("ASoC: cx20442: Don't ignore

This patch modifies deferred FIQ interrupt handler so it no longer uses

For modem_codec pin, declare static variable for storing its GPIO

don't request the modem_codec pin from the board init code anymore.
If the modem_codec GPIO lookup fails, skip initialization of

Scope of the change is limited to GPIO pins used by board specific
device drivers which will be updated by follow-up patches of the
series. Those are some OMAP GPIO (gpio-0-15) and most of Amstrad Delta
latch2 GPIO bank pins. Remaining pins of those banks, as well as
Amstrad Delta latch1 pins, will be addressed later.
Assign a label ("latch2") to the bank, enumerate its pins and put that
information, together with OMAP GPIO bank pins, in GPIO lookup tables.
Assign lookup tables to devices as soon as those devices are registered
and their names can be obtained.
A step froward in:
- removal of hard-coded GPIO numbers from drivers,
- removal of board mach includes from drivers,
- switching to dynamically assigned GPIO numbers.

The modem pm handler in the ams-delta board uses regulator_enable()
but does not check for a successful return code:
board-ams-delta.c:521:3: error: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Werror=unused-result]
It is not easy to propagate that return code to the callers in
uart_configure_port/uart_suspend_port/uart_resume_port, unless
we change all UART drivers, and it is unclear what those would
do with the return code.
Instead, this patch uses a runtime warning to replace the
compiletime warning. I have checked that the regulator in question
is hardcoded to a fixed-voltage GPIO regulator, and that should
never fail to get enabled if I understand the code right.

This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform code updates from Arnd Bergmann:
"This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings
several of the more minor and older platforms we have closer to
multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0
and realview Much of this is moving around header files from old mach
directories, but there are also some cleanup patches of debug_ll
(lowlevel debug per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts"

The separate struct bgpio_chip has been a pain to handle, both
by being confusingly similar in name to struct gpio_chip and
for being contained inside a struct so that struct gpio_chip
is contained in a struct contained in a struct, making several
steps of dereferencing necessary.
Make things simpler: include the fields directly into
<linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and
get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix
some of the member variables with bgpio_* and add proper
kerneldoc while we're at it.
Modify all users to handle the change and use a struct
gpio_chip directly. And while we're at it: replace all
container_of() dereferencing by gpiochip_get_data() and
registering the gpio_chip with gpiochip_add_data().

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

ASoC: Fixes for v3.7
Nothing too exciting except for the ams-delta change which is relatively
lerge due to the fact that the driver loading had been totally broken as
the driver needed a newer API to function.
The old method of registering with the ASoC core by creating a
"soc-audio" platform device no longer works for Amstrad Delta sound card
after recent changes to drvdata handling (commit
0998d06310, 'device-core: Ensure drvdata =
NULL when no driver is bound'.
Use snd_soc_register_card() method instead, as suggested by the ASoC
core generated warning message, and move both the card and codec
platform device registration to the arch board file where those belong.

After the CX20442 codec driver already takes care of enabling the codec
power for itself (commit f75a8ff67d,
"ASoC: cx20442: add bias control over a platform provided regulator"),
but before dropping the old bias control method from the Amstrad Delta
ASoC sound card file, which in fact keeps the modem power always on,
even on the ASoC device close for now, extend the modem setup with a
power management callback which toggles the regulator up to the modem's
needs, reusing the previously set up regulator consumer for this. Also,
drop the MODEM_NRESET pin setup from the modem initialization procedure,
as this operation was already ineffective since patch 1/3, and not
needed because the regulator is set up as initially enabled.

The Amstrad Delta on-board latch2 bit named MODEM_NRESET, now available
as a GPIO pin AMS_DELTA_GPIO_PIN_NMODEM_RESET, is used to power up/down
(bring into/out of a reset state) two distinct on-board devices
simultaneously: the modem, and the voice codec. As a consequence, that
bit is, or can be, manipulated concurrently by two drivers, or their
platform provided hooks.
Instead of updating those drivers to use the gpiolib API as a new method
of controlling the MODEM_NRESET pin state, like it was done to other
drivers accessing latch2 pins, and still being vulnerable to potential
concurrency conflicts, or trying to solve that sharing issue with a
custom piece of code, set up a fixed regulator device on top of that
GPIO pin, with the intention of updating both drivers to manipulate that
regulator, not the GPIO pin directly.
Before the ASoC driver is updated and the modem platform data expanded
with a power management callback for switching its power, the
ams_delta_latch_write() function, which still provides the old API for
accessing latch2 functionality from not updated drivers, is modified to
toggle the regulator instead of the MODEM_NRESET GPIO pin. A helper
function provided for balancing the regulator enable/disable operations,
together with the consumer data needed for tracking the regulator state,
will be removed once the drivers are updated.
Depends on patch series "ARM: OMAP1: ams-delta: replace custom I/O with
GPIO".

The main purpose of this patch is to fix several section mismatch
warnings from the board file and a few board specific drivers,
introduced with recent Amstrad Delta patch series, some of them rising
up only when building with CONFIG_MODULES not set.
While being at it, section tagging of all init data found in the board
file have been revised and hopefully corrected and/or optimized.

While resolving section mismatches introduced with recent patches
to for-next, a few dangerous, driver bind/unbind unaware section
tagging already present in mainline have been identified. Fix them.

There's no need to have these in plat/io.h.
While at it, clean up the includes to group them
like they typically are grouped.

LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board
files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this
patch adds omapfb_set_lcd_config() function that the board files can
call to set the LCD config.
This has the drawback that configuration can no longer come from the
bootloader. Of the boards supported by the kernel, this should only
affect N770 which depends on the data from the bootloader. This patch
adds an LCD config for N770 to its board files, but that is most
probably broken. Fixing this would need information about the HW setup
in N770 boards.
