When support for the MT6366 PMIC regulators was added, it was assumed
that it had the same functionality as MT6358. In reality there are
differences. A few regulators have different ranges, or were renamed
and repurposed, or removed altogether.
Add the 3 regulators that were missing from the original submission.
These are added for completeness. VSRAM_CORE is not used in existing
projects. VM18 and VMDDR feed DRAM related consumers, and are not used
in-kernel.

The "fixed" LDO regulators found on the MT6358 and MT6366 PMICs have
either no voltage selection register, or only one valid setting.
However these do have a fine voltage calibration setting that can
slightly boost the output voltage from 0 mV to 100 mV, in 10 mV
increments.
Add support for this by changing these into linear range regulators.
Some register definitions that are missing are also added.

Some configurations differ between chip variants, e,g. the register
to control the on of state of LDOA1 and SWB2. Thus, it is necessary
to choose the correct configuration for a dedicated device.
If the wrong configuration was used, the LDOA1 output that was
disabled by the bootloader was enabled in Kernel again.
Each chip variant gets its dedicated configuration selected by
the chip ID previously collected from MFD probe function.
The VTT enum value (tps65086_regulators) is shifted because not all
chip variants have a separate SWB2 switch. Sometimes they are merged.
So the configuration possibilities differ, thus the regulator
configuration arrays have a different length.

The new set of drivers for RZ/G2L MTU3a tries to enable compile-testing the
individual client drivers even when the MFD portion is disabled but gets it
wrong, causing a link failure when the core is in a loadable module but the
other drivers are built-in:
x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply':
pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write'

rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read'
It seems better not to add the extra complexity here but instead just use
a normal hard dependency, so remove the #else portion in the header along
with the "|| COMPILE_TEST". This could also be fixed by having slightly more
elaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper,
but in practice it's already possible to compile-test all these drivers
by enabling the mtd portion.

This commit prepares a following commit for the regulator part of the MFD.
The driver should support different device chips that differ in their
register definitions, for instance to control LDOA1 and SWB2.
So it is necessary to use a dedicated regulator description for a
specific device variant. Thus, the content from DEVICEID Register 1 is
used to choose a dedicated configuration between the different device
variants.

On some MAX 10 cards, the BMC firmware is not available to service
handshake registers during secure update erase and write phases at
normal speeds. This problem affects at least hwmon driver. When the MAX
10 hwmon driver tries to read the sensor values during a secure update,
the reads are slowed down (e.g., reading all D5005 sensors takes ~24s
which is magnitudes worse than the normal <0.02s).
Manage access to the handshake registers using a rw semaphore and a FW
state variable to prevent accesses during those secure update phases
and return -EBUSY instead.
If handshake_sys_reg_nranges == 0, don't update bwcfw_state as it is not
used. This avoids the locking cost.

Order the register blocks to have the masks in descending manner.

MIVR mask (RT5033_CHGCTRL4_MIVR_MASK), pre-charge current shift
(RT5033_CHGCTRL4_IPREC_SHIFT), internal timer disable

The fast charge timer type needs to be written on mask 0x38
(RT5033_CHGCTRL3_TIMER_MASK). To avoid a bit shift on application, change the
values of the timer types to fit the mask. Added the timout duration as a
comment. And the timer between TIMER8 and TIMER12 is most likely TIMER10, see
e.g. RT5036 [1] page 28 bottom.
Add value options for MIVR (Minimum Input Voltage Regulation).
Move RT5033_TE_ENABLE_MASK to the block "RT5033 CHGCTRL1 register", in order
to have the masks of the register collected there. To fit the naming scheme,
rename it to RT5033_CHGCTRL1_TE_EN_MASK.
Move RT5033_CHG_MAX_CURRENT to the block "RT5033 charger fast-charge current".
Add new defines RT5033_CV_MAX_VOLTAGE and RT5033_CHG_MAX_PRE_CURRENT to the

current limits".
In include/linux/mfd/rt5033.h, turn power_supply "psy" into a pointer in order

Merge series from Esteban Blanc <eblanc@baylibre.com>:
TPS6594 is a Power Management IC which provides regulators and others
features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and
PFSM (Pre-configurable Finite State Machine). The SoC and the PMIC can
communicate through the I2C or SPI interfaces.
TPS6594 is the super-set device while TPS6593 and LP8764 are derivatives.
This series adds support to TI TPS6594 PMIC and its derivatives.
Merge series from Andre Przywara <andre.przywara@arm.com>:
This patch series adds support for the X-Powers AXP15060 and AXP313a
PMIC, which are general purpose PMICs as seen on different boards with
different SOCs, mostly from Allwinner.
This is mostly a repost of the previous patches, combining both the
AXP313a and AXP15060 series, rebased on top of v6.4-rc3, and omitting
the patches that already got merged.
The first two patches are the successors of the AXP313a v10 post,
the third patch is based on Shengyu's AXP15060 v3 post.
There were no code changes, just some tiny context differences due to
the rebase, plus I added the newly gained tags.
As the DT bindings and the AXP15060 MFD part are already in the tree,
this is just completing support with the MFD part for the AXP313a, and
the regulator support for both PMICs.
The previous version of this driver included wildcards in file names
and descriptions. This patch renames the driver to only support MAX5970
and MAX5978, which are the only chips that the driver actually supports.

The AXP313a is a PMIC chip produced by X-Powers, it can be connected via
an I2C bus.
The name AXP1530 seems to appear as well, and this is what is used in
the BSP driver. From all we know it's the same chip, just a different
name. However we have only seen AXP313a chips in the wild, so go with
this name.
Compared to the other AXP PMICs it's a rather simple affair: just three
DCDC converters, three LDOs, and no battery charging support.
Describe the regmap and the MFD bits, along with the registers exposed
via I2C. Aside from the various regulators, also describe the power key
interrupts, and adjust the shutdown handler routine to use a different
register than the other PMICs.
Eventually advertise the device using the new compatible string.

The TWL4030 GPIO driver has a custom platform data .set_up()
callback to call back into the platform and do misc stuff such
as hog and export a GPIO for WLAN PWR on a specific OMAP3 board.
Avoid all the kludgery in the platform data and the boardfile
and just put the quirks right into the driver. Make it
conditional on OMAP3.
I think the exported GPIO is used by some kind of userspace
so ordinary DTS hogs will probably not work.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
Aaro reports problems on the OSK1 board after we altered
the dynamic base for GPIO allocations.
It appears this happens because the OMAP driver now
allocates GPIO numbers dynamically, so all that is
references by number is a bit up in the air.
Let's bite the bullet and try to just move the gpio_chip
in the tps65010 MFD driver over to using dynamic allocations.
Alter everything in the OSK1 board file to use a GPIO
descriptor table and lookups.
Utilize the NULL device to define some board-specific
GPIO lookups and use these to immediately look up the
same GPIOs, convert to IRQ numbers and pass as resources
to the devices. This is ugly but should work.
The .setup() callback for tps65010 was used for some GPIO
hogging, but since the OSK1 is the only user in the entire
kernel we can alter the signatures to something that
is helpful and make a clean transition.

Merge tag 'pwm/for-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding:
"The bulk of this is trivial conversions to the new .remove_new()
callback for drivers as part of Uwe's effort to clean that up.
Other than that a driver is added for Apple devices and various small
fixes are included for existing drivers.
Last but not least, this finally gets rid of the old pwm_request() and
pwm_free() APIs are removed since the last user was dropped in v6.3"

Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost breaks
even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions
All of these have been in linux-next for a while with no reported
issues.

The AXP15060 is a PMIC chip produced by X-Powers, and could be connected
via an I2C bus.
Describe the regmap and the MFD bits, along with the registers exposed
via I2C. Eventually advertise the device using a new compatible string
and add support for power off the system.
The driver would disable PEK function if IRQ is not configured in device
tree, since some boards (For example, Starfive Visionfive 2) didn't
connect IRQ line of PMIC to SOC.
GPIO function isn't enabled in this commit, since its configuration
operation is different from any existing AXP PMICs and needs
logic modification on existing driver. GPIO support might come in later
patches.

The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in
the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer
channels and one 32-bit timer channel. It supports the following
functions
- Counter
- Timer
- PWM
The 8/16/32 bit registers are mixed in each channel.
Add MTU3a core driver for RZ/G2L SoC. The core driver shares the
clk and channel register access for the other child devices like
Counter, PWM and Clock event.
