This patch adds all the core support and defines for the Cirrus
Logic CS42L92, CS47L92 and CS47L93 smart audio CODECs.
Registers or fields are named MADERA_* if it is part of the
common hardware platform and does not conflict with any other
Madera codecs. It is named CS47L15_* if it is unique to CS47L15
and conflicts with definitions on other codecs.

Currently we are relying on the exact match of the regulator name to
find MICVDD, we should add an explicit supply mapping to allow this to
be found more reliably.

When the driver is used with a subdevice that is disabled in the
kernel configuration, clang gets a little confused about the
control flow and fails to notice that n_subdevs is only
uninitialized when subdevs is NULL, and we check for that,
leading to a false-positive warning:
drivers/mfd/arizona-core.c:1423:19: error: variable 'n_subdevs' is uninitialized when used here
[-Werror,-Wuninitialized]
subdevs, n_subdevs, NULL, 0, NULL);
^~~~~~~~~
drivers/mfd/arizona-core.c:999:15: note: initialize the variable 'n_subdevs' to silence this warning
int n_subdevs, ret, i;
^
= 0
Ideally, we would rearrange the code to avoid all those early
initializations and have an explicit exit in each disabled case,
but it's much easier to chicken out and add one more initialization
here to shut up the warning.

The logic for setting the of_node on devices created by mfd did not set

The reset button on imx8mm-evk is tied to PWRON_B pin of bd71847 and the
long press duration is set to zero from OTP. The linux driver overrides
those values and breaks reset from button.
Overwriting OTP or bootloader configuration with some hardcoded defaults
is not desirable, keep already programmed values instead.

Pull more clk framework updates from Stephen Boyd:
"One more patch to remove io.h from clk-provider.h.
We used to need this include when we had clk_readl() and clk_writel(),
but those are gone now so this patch pushes the dependency out to the
users of clk-provider.h"
* tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
clk: Remove io.h from clk-provider.h
|

Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

I also reordered a couple includes when they weren't alphabetical and

Since there are more IOT2040 variants with identical hardware but
different asset tags, the asset tag matching should be adjusted to
support them.
For the board name "SIMATIC IOT2000", currently there are 2 types of
hardware, IOT2020 and IOT2040. Both are identical regarding the
intel_quark_i2c_gpio. In the future there will be no other devices with

Add support in code for the new forms of the host sleep event.
Detects the presence of this version of the command at runtime,
and use whichever form the EC supports. At this time, always
request the default timeout, and only report the failing response
via a WARN_ONCE(). Future versions could accept the sleep parameter
from outside the driver, and return the response information to
usermode or elsewhere.

hence is instantiated as a different driver.

The AXP223 can be used both using the RSB proprietary bus, or a more
traditional I2C bus. The RSB is a faster bus and provides more features
(like some integrity checks on the messages), so it's usually preferrable
to use it, but since it's proprietary, when we want to use the PMIC in a
multi-master setup, the i2c might make sense as well.
Let's add that possibility.

I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:
twl6040 0-004b: Failed to write 2d = 19: -121
And then any following register access will produce errors.
There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.
To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.
Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.
