Manipulating a list in the kernel isn't safe without some sort of
mutual exclusion. Add a mutex any time we access / modify
'mfd_of_node_list' to prevent possible crashes.

As of commit c7fe3bbfd622b5ee ('mfd: core: Use of_property_read_reg() to
parse "reg"'), all code in mfd_match_of_node_to_dev() compiles fine when
CONFIG_OF is disabled. As the sole caller of this function is
protected by IS_ENABLED(CONFIG_OF), the #ifdef inside the function can
be removed to increase build coverage, without impacting code size.

This reverts commit 2e3378f6c79a1b3f7855ded1ef306ea4406352ed.
Almost every register in this chip can be customized via OTP
memory. Somehow the value for R19, which decide if the flag is set
on read or write operation, seems to have been overwritten for the chip
the original patch were written for.

By adding the RTC alarm IRQ to the MFD cell as a resource, the child
driver (rtc) can simply query that IRQ, instead of having a lookup
table itself.
This change therefore allows the child driver to be simplified with

The ROHM BD72720 is a power management IC with a charger and coulomb
counter block which is closely related to the charger / coulomb counter
found from the BD71815, BD71828, BD71879 which are all supported by the
bd71828-power driver. Due to the similarities it makes sense to support
also the BD72720 with the same driver.

The BD71828 power-supply driver assumes register addresses to be 8-bit.
The new BD72720 will use stacked register maps to hide paging which is
done using secondary I2C slave address. This requires use of 9-bit
register addresses in the power-supply driver (added offset 0x100 to
the 8-bit hardware register addresses).
The cost is slightly used memory consumption as the members in the
struct pwr_regs will be changed from u8 to unsigned int, which means 3
byte increase / member / instance.
This is currently 14 members (expected to possibly be increased when
adding new variants / new functionality which may introduce new
registers, but not expected to grow much) and 2 instances (will be 3
instances when BD72720 gets added).
So, even if the number of registers grew to 50 it'd be 150 bytes /
instance. Assuming we eventually supported 5 variants, it'd be
5 * 150 bytes, which stays very reasonable considering systems we are
dealing with.
As a side note, we can reduce the "wasted space / member / instance" from
3 bytes to 1 byte, by using u16 instead of the unsigned int if needed. I
rather use unsigned int to be initially prepared for devices with 32 bit
registers if there is no need to count bytes.

The ROHM BD72720 has 6 pins which may be configured as GPIOs. The
GPIO1 ... GPIO5 and EPDEN pins. The configuration is done to OTP at the
manufacturing, and it can't be read at runtime. The device-tree is
required to tell the software which of the pins are used as GPIOs.
Keep the pin mapping static regardless the OTP. This way the user-space
can always access the BASE+N for GPIO(N+1) (N = 0 to 4), and BASE + 5
for the EPDEN pin. Do this by setting always the number of GPIOs to 6,
and by using the valid-mask to invalidate the pins which aren't configured
as GPIOs.
First two pins can be set to be either input or output by OTP. Direction
can't be changed by software. Rest of the pins can be set as outputs
only. All of the pins support generating interrupts.
Support the Input/Output state getting/setting and the output mode
configuration (open-drain/push-pull).

ROHM BD72720 is a power management IC which integrates 10 buck and 11 LDO
regulators. This PMIC has plenty of commonalities with the BD71828 and
BD71879.
The BD72720 does also have similar 'run-level'-concept as the BD71828 had.
It allows controlling the regulator's 'en masse', although only BUCK1
and LDO1 can utilize this in BD72720. Similar to BD71828, this 'en
masse' -control is not supported by this driver.

The new ROHM BD72720 PMIC has similarities with the BD71828. It makes
sense to support the regulator control for both PMICs using the same
driver. It is often more clear to have the IC specific functions and
globals named starting with the chip-name. So, as a preparatory step,
prefix the BD71828 specific functions and globals with the bd71828.
It would be tempting to try also removing the chip ID from those
functions which will be common for both PMICs. I have bad experiences on
this as it tends to lead to problems when yet another IC is being
supported with the same driver, and we will have some functions used for
all, some for two of the three, and some for just one. At this point
I used to start inventing wildcards like BD718XX or BD7272X. This
approach is pretty much always failing as we tend to eventually have
something like BD73900 - where all the wildcard stuff will break down.
So, my approach these days is to:
- keep the original chip-id prefix for anything that had it already
(and avoid the churn).
- use same prefix for all things that are used by multiple ICs -
typically the chip-ID of the first chip. This typically matches also
the driver and file names.
- use specific chip-ID as a prefix for anything which is specific to
just one chip.
As a preparatory step to adding the BD72720, add bd71828 prefix to all
commonly usable functions and globals.

The ROHM BD72720 is a power management IC which continues the BD71828
family of PMICs. Similarly to the BD71815 and BD71828, the BD72720
integrates regulators, charger, RTC, clock gate and GPIOs.
The main difference to the earlier PMICs is that the BD72720 has two
different I2C slave addresses. In addition to the registers behind the
'main I2C address', most of the charger (and to some extent LED) control
is done via registers behind a 'secondary I2C slave address', 0x4c.

ROHM has developed a so called "zero-correction" -algorithm to improve
the fuel-gauging accuracy close to the point where battery is depleted.
This relies on battery specific "VDR" (voltage drop rate) tables, which
are measured from the battery, and which describe the voltage drop rate.
More thorough explanation about the "zero correction" and "VDR"
parameters is here:
https://lore.kernel.org/all/676253b9-ff69-7891-1f26-a8b5bb5a421b@fi.rohmeurope.com/
Document the VDR zero-correction specific battery properties used by the
BD71815, BD71828, BD72720 and some other ROHM chargers. (Note, charger

Some of the chargers for lithium-ion batteries use a trickle-charging as
a first charging phase for very empty batteries, to "wake-up" the battery.
Trickle-charging is a low current, constant current phase. After the
voltage of the very empty battery has reached an upper limit for
trickle charging, the pre-charge phase is started with a higher current.
Allow defining the upper limit for trickle charging voltage, after which
the charging should be changed to the pre-charging.

The term 'trickle-charging' is used to describe a very slow charging
phase, where electrons "trickle-in" the battery.
There are two different use-cases for this type of charging. At least
some Li-Ion batteries can benefit from very slow, constant current,
pre-pre phase 'trickle-charging', if a battery is very empty.
Some other batteries use top-off phase 'trickle-charging', which is
different from the above case.
The battery bindings use the term 'trickle-charge' without specifying
which of the use-cases properties are addressing. This has already
caused some confusion.
Clarify that the 'trickle-charge-current-microamp' refers to the first
one, the "pre-pre" -charging use-case.

The ROHM BD72720 is a new PMIC with 10 BUCk and 11 LDO regulators.
The BD72720 is designed to support using the BUCK10 as a supply for
the LDOs 1 to 4. When the BUCK10 is used for this, it can be set to a
LDON_HEAD mode. In this mode, the BUCK10 voltage can't be controlled by
software, but the voltage is adjusted by PMIC to match the LDO1 .. LDO4
voltages with a given offset. Offset can be 50mV .. 300mV and is
changeable at 50mV steps.
Add 'ldon-head-microvolt' property to denote a board which is designed
to utilize the LDON_HEAD mode.
All other properties are already existing.

Brown paper bag time. This is a silly oversight where I missed to drop
the error condition checking to ensure we clean up on early error
returns. I have an internal unit testset coming up for this which will
catch all such issues going forward.

Commit 7bfe3b8ea6e3 ("Drivers: hv: Introduce mshv_vtl driver") added a
new generated header file for the offsets into the mshv_vtl_cpu_context
structure to be used by the low-level assembly code. But it didn't add
the .gitignore file to go with it, so 'git status' and friends will
mention it.
Let's add the gitignore file before somebody thinks that generated
header should be committed.

can't lead to any regressions for the existing setups
