The driver's probe() first registers regulators in a loop and then in a
second loop passes them as irq data to the interrupt handlers. However
the function to get the regulator for given name
tps65219_get_rdev_by_name() was a no-op due to argument passed by value,
not pointer, thus the second loop assigned always same value - from
previous loop. The interrupts, when fired, where executed with wrong
data. Compiler also noticed it:
drivers/regulator/tps65219-regulator.c: In function ‘tps65219_get_rdev_by_name’:
drivers/regulator/tps65219-regulator.c:292:60: error: parameter ‘dev’ set but not used [-Werror=unused-but-set-parameter]

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 5.15 but did exist in Linux 6.1.

Due to wrong interpretation of the specification,
custom implementation was used instead of standard regmap helper.

Make the error message more useful by reporting the actual regulator
name if devm_regulator_register() fails.

Testing .enable cannot tell if a regulator is enabled or not, check return
value of .is_enabled() instead.
Also remove unneeded ret variable.

The .bypass_val_on setting does not match the .bypass_mask setting, so the
.bypass_mask bit will never get set. Fix it by removing .bypass_val_on
setting, the regulator_set_bypass_regmap and regulator_get_bypass_regmap
helpers will use rdev->desc->bypass_mask as val_on if the val_on is 0.

The print function dev_err() is redundant because
platform_get_irq_byname() already prints an error.

The regulators set consists of 3 bucks DCDCs and 4 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.
Validation:
Visual check: cat /sys/kernel/debug/regulator/regulator_summary
Validation: userspace-consumer and virtual-regulator required
to test further
Enable/Disable:
cat /sys/devices/platform/userspace-consumer-VDDSHV_SD_IO_PMIC/state
echo disabled > /sys/devices/platform/
userspace-consumer-VDDSHV_SD_IO_PMIC/state
echo enabled > /sys/devices/platform/
userspace-consumer-VDDSHV_SD_IO_PMIC/state
Change voltage:
cat /sys/devices/platform/regulator-virtual-ldo1/min_microvolts
echo 1000000 > /sys/devices/platform/regulator-virtual-ldo1/
min_microvolts
echo 3000000 > /sys/devices/platform/regulator-virtual-ldo1/
