3a5e6e4985 regulator: tps65086: Select dedicated regulator config for chip variant
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.

10d3340441 mfd: rz-mtu3: Link time dependencies
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'
x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable'

arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get':
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.

c01467355f mfd: tps65086: Read DEVICE ID register 1 from device
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.

Pull gpio updates from Bartosz Golaszewski:
 "We have two new drivers, some improvements to the core code, lots of
  different updates to existing GPIO drivers and some dt-bindings on
  top.

  There's nothing controversial in here and almost everything has been
  in next for more than a week (95% a lot longer than this). The only
  thing that has spent less time in next is a new driver so no risk of
  regressions.

  The single merge pulls in changes that remove all usage of global GPIO

   - don't spam the kernel log with messages about hogs
   - remove old sysfs API cruft
   - improve handling of GPIO masks

  New drivers:
   - add a driver for the BlueField-3 GPIO controller
   - add GPIO support for the TPS65219 PMIC

  Driver improvements:
   - extend the gpio-aggregator driver to support ramp-up/ramp-down
     delay
   - remove unnecessary CONFIG_OF guards from gpio-aggregator
   - readability improvements in gpio-tangier
   - switch i2c drivers back to using probe() now that it's been

   - remove unused inclusions of of_gpio.h in several drivers
   - make pm ops static in gpio-davinci and fix a comment
   - use more devres in drivers to shrink and simplify the code
   - add missing include in gpio-sa1100

   - add permissions checks before accessing pins in gpio-tegra186
   - convert the gpio-zynq driver to using immutable irqchips
   - preserve output settings set by the bootloader in gpio-mpc8xxx

  Selftests:

867cae44f8 mfd: intel-m10-bmc: Manage access to MAX 10 fw handshake registers
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.

3d89761210 mfd: rt5033: Apply preparatory changes before adding rt5033-charger driver
Order the register blocks to have the masks in descending manner.

Add new defines for constant voltage shift (RT5033_CHGCTRL2_CV_SHIFT),
MIVR mask (RT5033_CHGCTRL4_MIVR_MASK), pre-charge current shift
(RT5033_CHGCTRL4_IPREC_SHIFT), internal timer disable
(RT5033_INT_TIMER_DISABLE), termination disable (RT5033_TE_DISABLE),
CFO disable (RT5033_CFO_DISABLE), UUG disable (RT5033_CHARGER_UUG_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
blocks "RT5033 charger constant charge voltage" and "RT5033 charger pre-charge
current limits".

In include/linux/mfd/rt5033.h, turn power_supply "psy" into a pointer in order
to use it in devm_power_supply_register().

4f7a2a08c7 mfd: rt5033: Fix STAT_MASK, HZ_MASK and AICR defines
The charger state mask RT5033_CHG_STAT_MASK should be 0x30 [1][2].

The high impedance mask RT5033_RT_HZ_MASK is actually value 0x02 [3] and is
assosiated to the RT5033 CHGCTRL1 register [4]. Accordingly also change
RT5033_CHARGER_HZ_ENABLE to 0x02 to avoid the need of a bit shift upon
application.

For input current limiting AICR mode, the define for the 1000 mA step was
missing [5]. Additionally add the define for DISABLE option. Concerning the
mask, remove RT5033_AICR_MODE_MASK because there is already
RT5033_CHGCTRL1_IAICR_MASK further up. They are redundant and the upper one
makes more sense to have the masks of a register colleted there as an
overview.
