f3e893626a mfd: ocelot: Add support for the vsc7512 chip via spi
The VSC7512 is a networking chip that contains several peripherals. Many of
these peripherals are currently supported by the VSC7513 and VSC7514 chips,
but those run on an internal CPU. The VSC7512 lacks this CPU, and must be
controlled externally.

Utilize the existing drivers by referencing the chip as an MFD. Add support
for the two MDIO buses, the internal phys, pinctrl, and serial GPIO.

Pull gpio updates from Bartosz Golaszewski:
 "Here are the updates for this merge window from the GPIO subsystem.

  We have more lines removed than added thanks to dropping of a driver
  for a platform that's no longer supported. Otherwise the changes are
  pretty straightforward: support for some new models, various
  improvements to existing drivers, some tweaks to the core library code
  and DT bindings updates.

  Summary:

That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or
none should be used in a driver.

Add support for the MT6331 PMIC with MT6332 Companion PMIC, found
in MT6795 Helio X10 smartphone platforms.

This combo has support for multiple devices but, for a start,
only the following have been implemented:
- Regulators (two instances, one in MT6331, one in MT6332)
- RTC (MT6331)
- Keys (MT6331)
- Interrupts (MT6331 also dispatches MT6332's interrupts)

There's more to be implemented, especially for MT6332, which

2a3c8f8a44 IIO new device support, features and minor fixes for 5.20
Several on-running cleanup efforts dominate this time, plus the DMA
 safety alignment issue identified due to improved understanding of
 the restrictions as a result of Catalin Marinas' efforts in that area.
 
 One immutable branch in here due to MFD and SPMI elements needed for
 the qcom-rradc driver.
 
 Device support
 * bmi088
   - Add support for bmi085 (accelerometer part of IMU)
   - Add support for bmi090l (accelerometer part of IMU)
 * mcp4922
   - Add support for single channel device MCP4921
 * rzg2l-adc
   - Add compatible and minor tweaks to support RZ/G2UL ADC
 * sca3300
   - Add support for scl3300 including refactoring driver to support
     multiple device types and cleanup noticed whilst working on driver.
 * spmi-rradc
   - New driver for Qualcomm SPMI Round Robin ADC including necessary
     additional utility functions in SPMI core and related MFD driver.
 * ti-dac55781
   - Add compatible for DAC121C081 which is very similar to existing parts.
 
 Features
 * core
   - Warn on iio_trigger_get() on an unregistered IIO trigger.
 * bma400
   - Triggered buffer support
   - Activity and step counting
   - Misc driver improvements such as devm and header ordering
 * cm32181
   - Add PM support.
 * cros_ec
   - Sensor location support
 * sx9324
   - Add precharge resistor setting
   - Add internal compensation resistor setting
   - Add CS idle/sleep mode.
 * sx9360
   - Add precharge resistor setting
 * vl53l0x
   - Handle reset GPIO, regulator and relax handling of irq type.
 
 Cleanup and minor fixes:
 
 Treewide changes
 - Cleanup of error handling in remove functions in many drivers.
 - Update dt-binding maintainers for a number of ADI bindings.
 - Several sets of conversion of drivers from device tree specific to
   generic device properties. Includes fixing up various related
   header and Kconfig issues.
 - Drop include of of.h from iio.h and fix up drivers that need to include
   it directly.
 - More moves of clusters of drivers into appropriate IIO_XXX namespaces.
 - Tree wide fix of a long running bug around DMA safety requirements.
   IIO was using __cacheline_aligned to pad iio_priv() structures. This
   worked for a long time by coincidence, but correct alignment is
   ARCH_KMALLOC_MINALIGN.  As there is activity around this area, introduce
   an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather
   than every driver in future. Note, there have been no reports of this
   bug in the wild, and it may not happen on any platforms supported by
   upstream, so no rush to backport these fixes.
 
 Other cleanup
 * core
   - Switch to ida_alloc()/free()
   - Drop unused iio_get_time_res()
   - Octal permissions and DEVICE_ATTR_* macros.
   - Cleanup bared unsigned usage.
 * MAINTAINERS
   - Add include/dt-bindings/iio/ to the main IIO entry.
 * ad5380
   - Comment syntax fix.
 * ad74413r
   - Call to for_each_set_bit_from(), with from value as 0 replaced.
 * ad7768-1
   - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core.
 * adxl345
   - Fix wrong address in dt-binding example.
 * adxl367
   - Drop extra update of FIFO watermark.
 * at91-sama5d2
   - Limit requested watermark to the hwfifo size.
 * bmg160, bme680
   - Typos
 * cio-dac
   - Switch to iomap rather than direct use of ioports
 * kxsd9
   - Replace CONFIG_PM guards with new PM macros that let the compiler
     cleanly remove the unused code and structures when !CONFIG_PM
 * lsm6dsx
   - Use new pm_sleep_ptr() and EXPORT_SIMPLE_DEV_PM_OPS(). Then move
     to Namespace.
 * meson_saradc - general cleanup.
   - Avoid attaching resources to iio_dev->dev
   - Use same struct device for all error messages
   - Convert to dev_err_probe() and use local struct device *dev to
     reduce code complexity.
   - Use devm_clk_get_optional() instead of hand rolling.
   - Use regmap_read_poll_timeout() instead of hand rolling.
 * mma7660
   - Drop ACPI_PTR() use that is unhelpful.
 * mpu3050
   - Stop exporting symbols not used outside of module
   - Switch to new DEFINE_RUNTIME_DEV_PM_OPS() macro and move to Namespace.
 * ping
   - Typo fix
 * qcom-spmi-rradc
   - Typo fix
 * sc27xx
   - Convert to generic struct u32_fract
 * srf08
   - Drop a redundant check on !val
 * st_lsm6dsx
   - Limit the requested watermark to the hwfifo size.
 * stm32-adc
   - Use generic_handle_domain_irq() instead of opencoding.
   - Fix handling of ADC disable.
 * stm32-dac
   - Use str_enabled_disable() instead of open coding.
 * stx104
   - Switch to iomap rather than direct use of ioports
 * tsc2046
   - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core.
 * tsl2563
   - Replace flush_scheduled_work() with cancel_delayed_work_sync()
   - Replace cancel_delayed_work() with cancel_delayed_work_sync()
 * vl53l0x
   - Make the VDD regulator optional by allowing a dummy regulator.

Cleanup and minor fixes:

Treewide changes
- Cleanup of error handling in remove functions in many drivers.
- Update dt-binding maintainers for a number of ADI bindings.
- Several sets of conversion of drivers from device tree specific to
  generic device properties. Includes fixing up various related
  header and Kconfig issues.
- Drop include of of.h from iio.h and fix up drivers that need to include
  it directly.
- More moves of clusters of drivers into appropriate IIO_XXX namespaces.
- Tree wide fix of a long running bug around DMA safety requirements.
  IIO was using __cacheline_aligned to pad iio_priv() structures. This
  worked for a long time by coincidence, but correct alignment is
  ARCH_KMALLOC_MINALIGN.  As there is activity around this area, introduce
  an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather
  than every driver in future. Note, there have been no reports of this
  bug in the wild, and it may not happen on any platforms supported by
  upstream, so no rush to backport these fixes.

7064d7d88b mfd: lpc_ich: Add support for pinctrl in non-ACPI system
Add support for non-ACPI systems, such as system that uses
Advanced Boot Loader (ABL) whereby a platform device has to be created
in order to bind with pin control and GPIO.

At the moment, Intel Apollo Lake In-Vehicle Infotainment (IVI) system
requires a driver to hide and unhide P2SB to lookup P2SB BAR and pass
the PCI BAR address to GPIO.

559793198f mfd: lpc_ich: Switch to generic p2sb_bar()
Instead of open coding p2sb_bar() functionality we are going to
use generic library. There is one more user en route.

This is more than just a clean-up. It also fixes a potential issue
seen when SPI BAR is 64-bit. The current code works if and only if
the PCI BAR of the hidden device is inside 4G address space. In case
when firmware decides to go above 4G, we will get a wrong address.

df76234276 mfd: bcm2835-pm: Add support for BCM2711
In BCM2711 the new RPiVid ASB took over V3D. The old ASB is still present
with the ISP and H264 bits, and V3D is in the same place in the new ASB
as the old one.

As per the devicetree bindings, BCM2711 will provide both the old and
new ASB resources, so get both of them and pass them into
'bcm2835-power,' which will take care of selecting which one to use
accordingly.

Since the RPiVid ASB's resources were being provided prior to formalizing
the bindings[1], also support the old DT files that didn't use
'reg-names.'

0c9b9c2ac0 mfd: core: Use acpi_dev_for_each_child()
Instead of walking the list of children of an ACPI device directly,
use acpi_dev_for_each_child() to carry out an action for all of
the given ACPI device's children.

This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).
