The recent change in commit 904ab34b54 ("usb: dwc3: ep0: Fail
enqueue() when racing with vbus_sess disconnect") added a check
to prevent queuing on ep0 if vbus_active is unset. However on
some configurations if dwc3 is configured as peripheral-only, this
flag is not set. In those cases, simply set vbus_active to true.

Being able to write to spmi registers via userspace is required
for quick debug and development. Enable it.
The regmap framework uses dev_name to create debugfs dir names.
So update the spmi devices to have proper names.

Reorder the pins and expose it as gpio 203, so that the UFS driver can

wakeup_source_register() expects a registered struct device *.
But in the subsys_register() path, device_register() is called
after wakeup_source_register(), which is incorrect. Hence,
flip the order of registrations. Also as an extension, reorder
the error-handling path of subsys_register() and the cleanup
sequence in subsys_unregister().

Currently, both the regular and debug spmi pmic arbiter devices
are probed in the same initcall order (arch_init). This is fine.
However, most of the sepolicy rules set in the userspace are
for the PMIC devices under spmi-0 bus. If the debug spmi pmic
arbiter device probes first and takes "spmi-0" name, then the
sepolicy rules set will be broken. Fix it by changing the
probe init order of debug spmi pmic arbiter device to module
init.

The I2C PMIC Controller is used by multi-function PMIC devices
which communicate over the I2C bus. The controller enumerates
all child nodes as platform devices, and instantiates a regmap
interface for them to communicate over the I2C bus.
The controller also controls interrupts for all of the children
platform devices. The controller handles the summary interrupt
by deciphering which peripheral triggered the interrupt, and
which of the peripheral interrupts were triggered. Finally, it
calls the interrupt handlers for each of the virtual interrupts
that were registered.

pmic_gpio_child_to_parent_hwirq() and
gpiochip_populate_parent_fwspec_fourcell() translate a pinctrl-
spmi-gpio irqspec to an SPMI controller irqspec. When they do
this, they use a fixed SPMI slave ID of 0 and a fixed GPIO
peripheral offset of 0xC0 (corresponding to SPMI address 0xC000).
This translation results in an incorrect irqspec for secondary
PMICs that don't have a slave ID of 0 as well as for PMIC chips
which have GPIO peripherals located at a base address other than
0xC000.
Correct this issue by passing the slave ID of the pinctrl-spmi-
gpio device's parent in the SPMI controller irqspec and by
calculating the peripheral ID base from the device tree 'reg'
property of the pinctrl-spmi-gpio device.

Currently, if the GPIO is configured as output in the bootloader
and user changes the mode to input in HLOS, it would end up
getting configured as input/output. Functionally, this is fine;
however, there may be some requirements where the output needs
to be disabled so that it can be used only for input.
Add support to enable/disable output mode through "output-enable"
or "output-disable" pinctrl properties.

Currently, when handling the SPMI summary interrupt, the hw_irq
number is calculated based on SID, Peripheral ID, IRQ index and
APID. This is then passed to irq_find_mapping() to see if a
mapping exists for this hw_irq and if available, invoke the
interrupt handler. Since the IRQ index uses an "int" type, hw_irq
which is of unsigned long data type can take a large value when
SID has its MSB set to 1 and the type conversion happens. Because
of this, irq_find_mapping() returns 0 as there is no mapping
for this hw_irq. This ends up invoking cleanup_irq() as if
the interrupt is spurious whereas it is actually a valid
interrupt. Fix this by using the proper data type (u32) for id.
