Some usb controller drivers may not support extcon but use
usb role class as it's the preferred approach, so to support
usb dual role switch with usb role class, add usb role class
consumer support.

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.

If disable vbus/id irq, it will lead to wakeup system fail

wakeup are the same interrupt line. So remove disable vbus/id

On some boards the 5V vboost-regulator for powering devices connected to
the micro USB connector is not controlled through a GPIO. This happens
for example when the 5V vboost-regulator is integrated into the charger IC
and controlled over I2C.
Add support for controlling the 5V vboost-regulator through the regulator
framework for such boards.

On some X86 Android tablets the DSTD lack the INT3496 ACPI device,
while also not handling micro USB port ID pin events inside the DSDT
(instead the forked factory image kernel has things hardcoded).
The new drivers/platform/x86/x86-android-tablets.c module manually
instantiates an intel-int3496 device for these tablets.
Add support to the extcon-intel-int3496 driver to bind to devices
without an ACPI companion and export a normal platform_device
modalias for automatic module loading.

Some DSDTs are buggy and do a read from the ID pin during the ACPI
initialization, causing the pin to be marked as owned by:
"ACPI:OpRegion" and causing gpiod_get() to fail with -EBUSY.
Pass the GPIOD_FLAGS_BIT_NONEXCLUSIVE flag to the gpiod_get() call
to work around this.

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.
