SM5703 is another MFD from Silicon Mitus which has a very similar MUIC
unit to the one in SM5502. The only difference I've noticed is slightly different
configuration only enables the interrupts which are exactly the same as on SM5502.
If we make use of different interrupts in the future, this can be improved by having
a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter)
is working properly.

The extcon_get_extcon_dev() function returns error pointers on error,
NULL when it's a -EPROBE_DEFER defer situation, and ERR_PTR(-ENODEV)
when the CONFIG_EXTCON option is disabled. This is very complicated for
the callers to handle and a number of them had bugs that would lead to
an Oops.
In real life, there are two things which prevented crashes. First,
error pointers would only be returned if there was bug in the caller
where they passed a NULL "extcon_name" and none of them do that.
Second, only two out of the eight drivers will build when CONFIG_EXTCON
is disabled.
The normal way to write this would be to return -EPROBE_DEFER directly
when appropriate and return NULL when CONFIG_EXTCON is disabled. Then
the error handling is simple and just looks like:
dev->edev = extcon_get_extcon_dev(acpi_dev_name(adev));
if (IS_ERR(dev->edev))
return PTR_ERR(dev->edev);
For the two drivers which can build with CONFIG_EXTCON disabled, then
extcon_get_extcon_dev() will now return NULL which is not treated as an
error and the probe will continue successfully. Those two drivers are
"typec_fusb302" and "max8997-battery". In the original code, the
typec_fusb302 driver had an 800ms hang in tcpm_get_current_limit() but
now that function is a no-op. For the max8997-battery driver everything
should continue working as is.

Make cht_wc_extcon_get_id() report RID_A for ACA adapters, instead of
reporting ID_FLOAT.
According to the spec. we should read the USB-ID pin ADC value
to determine the resistance of the used pull-down resister and
then return RID_A / RID_B / RID_C based on this. But all "Accessory
Charger Adapter"s (ACAs) which users can actually buy always use
a combination of a charging port with one or more USB-A ports, so
they should always use a resistor indicating RID_A. But the spec
is hard to read / badly-worded so some of them actually indicate
they are a RID_B ACA even though they clearly are a RID_A ACA.
To workaround this simply always return INTEL_USB_RID_A, which
matches all the ACAs which users can actually buy.

So far the extcon-intel-cht-wc code has only been tested on devices with
a Type-C connector with USB-PD, USB3 (superspeed) and DP-altmode support
through a FUSB302 Type-C controller.
Some devices with the intel-cht-wc PMIC however come with an USB-micro-B
connector, or an USB-2 only Type-C connector without USB-PD.
Which device-model we are running on can be identified with the new
cht_wc_model intel_soc_pmic field. On models without a Type-C controller
the extcon code must control the Vbus 5V boost converter and the USB role
switch depending on the detected cable-type.

use low level P-Unit semaphore lock for axp288 register
accesses directly and for more than one access a time,
to reduce the number of times this semaphore is locked
and released which is an expensive operation.
i2c-bus to the XPower is shared between the kernel and the
SoCs P-Unit. The P-Unit has a semaphore wich the kernel must
lock for axp288 register accesses. When the P-Unit semaphore
is locked CPU and GPU power states cannot change or the system
will freeze.
The P-Unit semaphore lock is already managed inside the regmap
access logic, but for each access the semaphore is locked and
released. So use directly iosf_mbi_(un)block_punit_i2c_access(),
we are safe in doing so because nested calls to the same
semaphore are turned to nops.

SM5504 is another MUIC from Silicon Mitus that is fairly similar
to SM5502. They seem to use the same register set, but:
- SM5504 has some additional bits in SM5502_REG_CONTROL
- SM5504 has a quite different set of interrupts
- SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7)
Overall it's minor and we can support this by defining a separate

Here is the "big" set of driver core changes for 5.13-rc1.
Nothing major, just lots of little core changes and cleanups, notable
things are:
- finally set fw_devlink=on by default. All reported issues
with this have been shaken out over the past 9 months or so,
but we will be paying attention to any fallout here in case we
need to revert this as the default boot value (symptoms of
problems are a simple lack of booting)
- fixes found to be needed by fw_devlink=on value in some
subsystems (like clock).
- delayed work initialization cleanup
- driver core cleanups and minor updates
- software node cleanups and tweaks
- devtmpfs cleanups
- minor debugfs cleanups
All of these have been in linux-next for a while with no reported
issues.

Few drivers implement remove call-back only for ensuring a delayed
work gets cancelled prior driver removal. Clean-up these by switching
to use devm_delayed_work_autocancel() instead.
Additionally, this helps avoiding mixing devm and manual resource
management and cleans up a (theoretical?) bug from extconn-palmas.c
and extcon-qcom-spmi-misc.c where (devm managed)IRQ might schedule
new work item after wq was cleaned at remove().
This change is compile-tested only. All testing is appreciated.

The jack handling for arizona codecs is being refactored so that it is
done directly by the codec drivers, instead of having an extcon-driver
bind to a separate "arizona-extcon" child-device for this.
drivers/mfd/arizona-core.c has already been updated to no longer
instantiate an "arizona-extcon" child-device for the arizona codecs.
This means that the "arizona-extcon" driver is no longer useful
(there are no longer any devices for it to bind to).
This commit drops the extcon Kconfig / Makefile bits and moves
drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c .
This is a preparation patch for converting the arizona extcon-driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.

Before this commit the extcon-arizona code was mixing pm_runtime_get()
and pm_runtime_get_sync() in different places.
In all places where pm_runtime_get[_sync]() is called, the code
makes use of the device immediately after the call.
This means that we should always use pm_runtime_get_sync().

The initial value of the GPIO should match the info->micd_modes[0].gpio
value. arizona_extcon_probe() already stores the necessary flag in a
mode variable, but instead of passing mode as flags to the gpiod_get()
it was using a hardcoded GPIOD_OUT_LOW.
