The USB regulator was removed for AB8500 in
commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator").
It was then added for AB8505 in
commit 547f384f33db ("regulator: ab8500: add support for ab8505").
However, there was never an entry added for it in
ab8505_regulator_match. This causes all regulators after it
to be initialized with the wrong device tree data, eventually
leading to an out-of-bounds array read.
Given that it is not used anywhere in the kernel, it seems
likely that similar arguments against supporting it exist for
AB8505 (it is controlled by hardware).
Therefore, simply remove it like for AB8500 instead of adding
an entry in ab8505_regulator_match.

Depends on board design, the gpio controlling regulator may
connects with a big capacitance. When need off, it takes some time
to let the regulator to be truly off. If not add enough delay, the
regulator might have always been on, so introduce off-on-delay to
handle such case.

The generic voltage balancer doesn't work correctly if one of regulator
couples turns off. Currently there are no users in kernel for that case,
although let's explicitly show that this case is unsupported for those who
will try to use that feature.

Pull regulator fixes from Mark Brown:
"There are a few core fixes here around error handling and handling if
suspend mode configuration and some driver specific fixes here but the
most important change is the fix to the fixed-regulator DT schema
conversion introduced during the last merge window.
That fixes one of the last two errors preventing successful execution
of "make dt_binding_check" which will be enormously helpful for DT
schema development"

Note that now that we have a good non-devm API for getting GPIO from

regulator core takes care of managing lifetime of "enable" GPIO and we
were immediately detaching requested GPIO from devm anyway.

Currently the suspend reg_field maps to the pmic voltage selection bits
and is used during suspend_enabe/disable() and during get_mode(). This
seems to be wrong for both use cases.
Use case one (suspend_enabe/disable):
Those callbacks are used to mark a regulator device as enabled/disabled
during suspend. Marking the regulator enabled during suspend is done by
the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers.
Setting this bit tells the DA9062 PMIC state machine to keep the
regulator on in POWERDOWN mode and switch to suspend voltage.
Use case two (get_mode):
The get_mode callback is used to retrieve the active mode state. Since
the regulator-setting-A is used for the active state and
regulator-setting-B for the suspend state there is no need to check
which regulator setting is active.

Pull LED updates from Jacek Anaszewski:
"In this cycle we've finally managed to contribute the patch set
sorting out LED naming issues. Besides that there are many changes
scattered among various LED class drivers and triggers.
LED naming related improvements:
- add new 'function' and 'color' fwnode properties and deprecate
'label' property which has been frequently abused for conveying
vendor specific names that have been available in sysfs anyway
- introduce a set of standard LED_FUNCTION* definitions
- introduce a set of standard LED_COLOR_ID* definitions
- add a new {devm_}led_classdev_register_ext() API with the
capability of automatic LED name composition basing on the
properties available in the passed fwnode; the function is
backwards compatible in a sense that it uses 'label' data, if
present in the fwnode, for creating LED name
- add tools/leds/get_led_device_info.sh script for retrieving LED
vendor, product and bus names, if applicable; it also performs
basic validation of an LED name
- update following drivers and their DT bindings to use the new LED
registration API:
- leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
Other LED class improvements:
- replace {devm_}led_classdev_register() macros with inlines
- allow to call led_classdev_unregister() unconditionally
- switch to use fwnode instead of be stuck with OF one
LED triggers improvements:
- led-triggers:
- fix dereferencing of null pointer
- fix a memory leak bug
- ledtrig-gpio:
- GPIO 0 is valid
Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
more complete driver exists, based on a generic driver for the AMD
SOCs gpio-controller, supporting LEDs as well other devices:
- drop profile field from priv data
- drop iosize field from priv data
- drop enum_apu_led_platform_types
- drop superseeded apu2/3 led support
- add pr_fmt prefix for better log output
- fix error message on probing failure
Other misc fixes and improvements to existing LED class drivers:
- leds-ns2, leds-max77650:
- add of_node_put() before return
- leds-pwm, leds-is31fl32xx:
- use struct_size() helper
- leds-lm3697, leds-lm36274, leds-lm3532:
- switch to use fwnode_property_count_uXX()
- leds-lm3532:
- fix brightness control for i2c mode
- change the define for the fs current register
- fixes for the driver for stability
- add full scale current configuration
- dt: Add property for full scale current.
- avoid potentially unpaired regulator calls
- move static keyword to the front of declarations
- fix optional led-max-microamp prop error handling
- leds-max77650:
- add of_node_put() before return
- add MODULE_ALIAS()
- Switch to fwnode property API
- leds-as3645a:
- fix misuse of strlcpy
- leds-netxbig:
- add of_node_put() in netxbig_leds_get_of_pdata()
- remove legacy board-file support
- leds-is31fl319x:
- simplify getting the adapter of a client
- leds-ti-lmu-common:
- fix coccinelle issue
- move static keyword to the front of declaration
- leds-syscon:
- use resource managed variant of device register
- leds-ktd2692:
- fix a typo in the name of a constant
- leds-lp5562:
- allow firmware files up to the maximum length
- leds-an30259a:
- fix typo
- leds-pca953x:

root regulator node but the dt-bindings specifies it as subnode
properties for the regulator-state-[mem/disk/standby] node. The only DT
using this bindings currently is the at91-sama5d2_xplained.dts and this
DT uses it correctly. I don't know if it isn't tested but it can't work
without this fix.

regulator_uV_show() is missing error handling if regulator_get_voltage_rdev()
returns negative values. Instead it prints the errno as a string, e.g. -EINVAL
as "-22" which could be interpreted as -22 µV.
We also do not need to hold the lock while converting the integer to a string.

This fixes 11da04af0d3b, as devm_gpiod_get_from_of_node() does
not do translation "con-id" -> "con-id-gpios" that our bindings expects,
and therefore it was wrong to change connection ID to be simply "enable"
when moving to using devm_gpiod_get_from_of_node().

Pro5 SoC has same scheme of USB3 VBUS as Pro4, so the data for Pro5 is
equivalent to Pro4.

This commit adds the possibility to choose the compatible
"regulator-fixed-clock" in devicetree.
This is a special regulator-fixed that has to have a clock, from which
the regulator gets switched on and off.

The value under 's2mps11->ext_control_gpiod[i]' is assigned to local
variable and used in probe in one place before. Use it consistently
later so code will be easier to read.

Use rdev->regmap/&rdev->dev instead of lp87565->regmap/lp87565->dev.
In additional, the lp87565->dev actually is the parent mfd device,
so the dev_err message is misleading here with lp87565->dev.

The CS GPIO line is clearly optional GPIO (and marked as such in the
binding document) and we should handle it accordingly. The current code
treats all errors as meaning that there is no GPIO defined, which is
wrong, as it does not handle deferrals raised by the underlying code
properly, nor does it recognize non-existing GPIO from any other
initialization error.
As far as I can see the only reason the driver, unlike all others,
is using OF-specific devm_gpiod_get_from_of_node() so that it can
assign a custom label to the selected GPIO line. Given that noone else
needs that, it should not be doing that either.
Let's switch to using more appropriate devm_gpiod_get_optional().
