The config transactions "scheduler" was hopelessly broken,
repeating completed transaction instead of picking up
next pending one.
Fixed now. Also improved debug messages.

Apparently the ab8500_gpadc_sw_hw_convert function got renamed
from ab8500_gpadc_convert to ab8500_gpadc_sw_hw_convert in
commit 734823462 "mfd: ab8500-gpadc: Add gpadc hw conversion",
but the export for this function did not get changed at the
same time, causing this allyesconfig error:
ERROR: "ab8500_gpadc_sw_hw_convert" [drivers/hwmon/ab8500.ko] undefined!
This patch fixes the export.

This patch adds all necessary header files and Kbuild plumbing for the
core driver for Silicon Laboratories Si476x series of AM/FM tuner
chips.
The driver as a whole is implemented as an MFD device and this patch
adds a core portion of it that provides all the necessary
functionality to the two other drivers that represent radio and audio
codec subsystems of the chip.

RTS5249 supports SD UHS-II interface.
In order to support SD UHS-II，the definitions of some internal
registers of RTS5249 have to be modified and are different from its
predecessors. So we need this patch to ensure RTS5249 can work, even
SD/MMC stack doesn't support UHS-II interface.

Add properties for some of the more important bits of platform data and

The main aim for this cycle is to have the u8540 booting to a
console. However, the u8540 doesn't support all of the u8500
platform devices yet. After this stage is complete we can then
fill in the inadequacies, such as specific clock support at a
later date. To achieve this we're placing devices supported by
all platforms into a common device structure and the remaining
ones into a platform specific one.

The abx500-clk driver is initiated at arch_initcall level. Moreover it
is relying on the ab8500-sysctrl API to be available. Therefore move
ab8500-sysctrl to arch_initcall level as well. The device is already
added before the abx500 clk device, thus it will be probed before as
well, which is exactly what we want.

Currently we check to see if we obtained the Tightly Coupled Program

have it. It's more traditional to return early if we don't have it.
This way we can flatten most of the function's code down to a single

For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

The Kconfig entry for DA9055 PMIC Support selects PMIC_DA9055. That was
probably inspired by the similar select statement in the entry for
DA9052/53 PMIC with I2C. But the DA9055 PMIC only comes in an I2C
variant and its driver doesn't need a separate Kconfig symbol for shared
code. In any case, this select can be dropped as PMIC_DA9055 doesn't
exist.

Palmas device have three different i2c addresses. The device creates
the two new dummy i2c clients for accessing the register by using
primary client adapter. This new dummy i2c client have their of_node
as NULL.
The dummy i2c client is used for registering interrupt and on this,
it creates irq domain handle. This created irq domain handle has
their of_node as NULL.
Now when any child of this device is registered through the DT as
follows:
palmas: tps65913@58 {
::::::::::::::::::
#interrupt-cells = <2>;
interrupt-controller;
palmas_rtc {
compatible = "ti,palmas-rtc";
interrupt-parent = <&palmas>;
interrupts = <8 0>;
};
::::::::::;;;
};
And child driver (palam-rtc in this case) get their irq number as
irq = platform_get_irq(pdev, 0);
The returned irq number is error in this case. The reason is that
the created irq_domain handle for the palmas interrupt does not have
valid node and so matching of node fails with palmas node.
Hence initialising the newly dummy created client->of_node with the
primary clients of_node so that irq_domain handle have proper of_node
for matching.
