The Texas Instruments DAC7512 has the exact same pinout, programming
interface and power-down modes as the Texas Instruments DAC121S101 and
Analog Devices AD5320, which are already supported by the IIO driver
ad5446.c. Remove the duplicate misc driver.
This requires user space to migrate to the standardized IIO sysfs ABI.
(In other words, it needs to change a filename.)
The IIO driver supports the chip's features more fully, e.g. the ability
to power down the output or choose one of the available powerdown modes.
There is an oddity with the misc driver in that it initializes the SPI
slave to SPI_MODE_0, in contradiction to the datasheet which specifies
that data is latched in on the falling edge, implying that SPI_MODE_1
or SPI_MODE_2 must be used. Another oddity is that Kconfig and the
MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it
actually has 12-bit.

Move all the EDAC core functionality behind CONFIG_EDAC and get rid of
that indirection. Update defconfigs which had it.
While at it, fix dependencies such that EDAC depends on RAS for the

Defconfig additions, removals, etc. Almost all of them just turn on
drivers that we want on some platform, usually after the driver
has been merged into mainline.
There is now a new defconfig file for tango4.

This doesn't have any benefit apart from saving a small amount of memory
when it is disabled. The ifdef hackery in the code makes it dirty
unnecessarily.
Clean it up by removing the Kconfig option completely. Few defconfigs
are also updated and CONFIG_CPU_FREQ_STAT_DETAILS is replaced with
CONFIG_CPU_FREQ_STAT now in them, as users wanted stats to be enabled.

The PXA defconfig compiles the legacy MPU3050 driver as a module,
but the device does not appear in device trees nor board files, so

The Kconfig and file naming for the PM8xxx driver is totally
confusing:
- Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel
users depending on or selecting either at random.
- A driver file named pm8921-core.c even if it is indeed
used by the whole PM8xxx family of chips.
- An irqchip named pm8xxx since it was (I guess) realized that
the driver was generic for all pm8xxx PMICs.
As I may want to add support for PM8901 this is starting to get
really messy. Fix this situation by:
- Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX
and convert all users, including LEDs Kconfig and ARM defconfigs
for qcom and multi_v7 to use that single symbol.
- Renaming the driver to qcom-pm8xxx.c to fit along the two
other qcom* prefixed drivers.
- Rename functions withing the driver from 8921 to 8xxx to
indicate it is generic.
- Just drop the =m config from the pxa_defconfig, I have no clue
why it is even there, it is not a Qualcomm platform. (Possibly
older Kconfig noise from saveconfig.)

If both legacy and device-tree machines are mixed in the same defconfig,
the legacy boards don't boot up anymore with gpio request deferral
errors.
This is seen when attempting to run akita, borzoi, spitz, terrier, or
tosa in qemu with pxa_defconfig.
The real reason behind is that gpio handling for pxa in its current
state cannot be built for _both_ a devicetree machine (ie. pxa-dt.c) and
a non devicetree machine (ie. corgi, tosa, ...).
This is turn is because for devicetree a pinctrl is enforced for the
machine, and a pinctrl driver is required. If it's not available,
pxa_gpio_request() fails on pinctrl_request_gpio() and returns
-EPROBE_DEFER. It was introduced by commit f806dac593
("ARM: pxa: activate pinctrl for device-tree machines").
Now the true chicken and egg problem is than machine files,
ie. arch/arm/mach-pxa/xxx.c are using gpio before the drivers are
probed, in the init_machine() function, and that's why pinctrl/gpio for
legacy machine files is a bit difficult.
As for now, to keep the compilation coverage and testing of legacy
machines, this patch removes the 2 devicetree machines from
pxa_defconfig.

GPIO_SYSFS is a common kernel functionality, not something
that a board specific Kconfig should have to worry about.
In MIOA701, we get a warning about the select when CONFIG_SYSFS
is disabled:
warning: (MACH_MIOA701) selects GPIO_SYSFS which has unmet direct dependencies (GPIOLIB && SYSFS)
This just removes the select and instead enables the symbol in
the defconfig file.

Add a defconfig covering all known pxa board, ie. all selectable machine
files in arch/arm/mach-pxa/*.c.
This defconfig was built by doing :
- aggregation of all known defconfigs by cat
am200epdkit_defconfig
cm_x2xx_defconfig
cm_x300_defconfig
colibri_pxa270_defconfig
colibri_pxa300_defconfig

- manual make menuconfig to ensure :
- all pxa implementation were selected
- all drivers were transformed into modules rather than builtin
=> as a consequence this single kernel will rely on an initramfs
=> as kernel size matters on pxa, each machine can take the subset
of modules required for it to work
- all missed configurations are selected verified by :
=> grep -i pxa .config | grep "is not set"
=> this should only show the left on purpose options (either not
selectable or sharpsl exception below)
- CONFIG_PXA_SHARPSL was disabled
This breaks the boot very early on any non Sharp platform, see
head-sharpsl.S
This defconfig was tested as booting up to the login phase on :
- lubbock (pxa25x)
- mainstone (pxa27x)
- zylonite (pxa3xx)
The completion of this work will require to :
- parse manually all the arch/arm/mach-pxa/*c files, look for all
platform devices added, and verify they are all in pxa_defconfig
- do the same to ensure all pxa specific drivers (leds, gpio, ...) are
included
