is the introduction of snd_soc_component, which will help more generic
handling of SoC and off-SoC components.
Also, snd_BUG_ON() macro is enabled unconditionally now due to its
misuses, so people might hit kernel warnings (it's a good thing for

- spear
- tegra

One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was a
patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then.

This implements device tree support for the AB3100 regulators
driver. The initial settings are moved out of platform data
and into the driver for the device tree case, as it appears
that there is no way to supply this as AUXDATA for an I2C
device. The style and bindings are heavily inspired by
Lee Jones' style for AB8500.

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.

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

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

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.
